Subject: [D90] Gas Cap Replacement

Since I lost my gascap at a gas station a couple of days ago, I went in search of a new one at the local auto parts store. Their computer didn't even list Land Rovers so on a whim we tried the cap for a '97 Land Cruiser - - and walla, it worked

Part # - Stant 10825 Fuel Cap

Subject: [D90] Part numbers

As promised,here are the part numbers for the fuel filler's :

NTC2655 the extension tube for jerrycans

the fuel filler fitted to European defenders,capable of accepting the extended filler are :
NTC 2676 filler fuel (leaded and diesel)
NTC 2690 " " (unleaded,don't know the difference....colour?? maybe size?,best to go for the diesel one,I DEFINITELY know that works)
ESR1650 Seal
NTC 2757 filler cap (non locked,vented)
RTC 4740 filler cap (Locking,vented)
RTC 4741 filler cap (locking,non vented.....probably this one you want to use for efi engines with pressure sense)

The pipe that goes from the filler tube to the tank is NTC 2338,but I don't know if it will fit the rear tanks.you may be able to use the existing pipe??

have fun!!

Subject: [D90] Non-NAS Fuel Filler Tube

Just installed the non-NAS diesel fuel filler tube (without the restrictor) to permit faster re-fueling, esp. with NATO cans. Got it from Rovers North - 802-879-0032, but probably any dealer could order it - P/N is WLH100570, for 90/110, $30.00. The unleaded-type NATO flex spout was more than the filler tube - $35.75, also from RN, P/N RTC7085.

The filler tube install is very easy - the only thing holding it in place are the two hose clamps for the rubber hose to the tank and the breather hose. Your existing gas cap works fine.

Technically - probably illegal - install at your own risk. But here in California, anyway, you can't find leaded gas, and if you leave the little warning sticker next to the gas cap, I'd think the average smog shop wouldn't notice, and if they do, slap the old filler back in.

Besides which, my lovely wife is not gonna be all that happy sitting on a gas tank..... It's a perception thing.... ;~)

I dunno if it was mentioned already on this list (old-timer's setting in!) but there is an outfit called Transfer Flow, Inc. which specializes in add-on tanks for a variety of vehicles:
http://www.transferflow.com/

The neat thing about their stuff is the flow control system, which automatically balances flow from the aux tank to the main one, with a neat little dash-mounted readout of volume in each. Their stuff is available for a lot of US pickups/RVs/trucks, but they may have something that would work for us, but pro'ly sitting in the bed of the D-90. Howevver, if anyone has a real interest in this, maybe TF could be approached to see what they suggest. They may be able to fabricate something for us.

I've had BP 9gal. tank installed for a couple of years and its great. Installed it before going out to Colorado. If you hard core wheel then get the 9 gal. tank it tucks up out of the way very neatly and doesn't hang below the frame. I also had a custom skid plate made up for it. The only pain is filling it from the wheel well with 36" tires. I'm looking into getting a filler assembly for it.

Fuel Pumps (includes fuel pump relays)

Subject: [D90] stalling problem

Hey All
With regard to the suggestion of replacing the fuel pump relay--It is not a standard 4 pin relay on the NAS D-90. It is a special 5 pin relay with two outputs and (I think) a diode incorporated into it. It runs both the fuel pump and the O2 sensor heater circuits. If you fit a standard 5 pin relay you will end up with a dead battery as the O2 heaters will stay energized with the ignition off. There is no cheap substitute for this part.

Any late modle chev. p/u pump is identical. I changed mine out with a 97 p/u pump, only difference is where the hose attatches to the top. One is ribbed (I believe it was the LR). I used a small piece of fuel line and hose clamp and it worked great. You can pick one up new for about 80 bucks.

Chris Velardi tchris@freewwweb.com adds:
The one I used to replace the stock one was an 89 Cadilac Seville made by AC and puts out 30lbs of pressure (this is important not every model puts out 30 lbs.) You must cut off the old connector and put on two female spades. The tank and skid plate must be dropped all the lines must be removed to replace it. (it's a bitch)

Subject: Re: [D90] Fuel pump

A few years back I went to replace my RR in tank fuel pump because it failed* One of the suppliers I spoke to was nice enough to be honest with me and told me the fuel pump itself rarely fails but the wires to the pump lose their connection because of bad epoxy that seals the wire connections to the head of the pump . Sure enough I took the assembly out and the epoxies had given up it hold on the connection and the wires were barley making contact. I re-soldered , re-epoxies, and re-installed ..never had problems again. And saved some big bucks to . Thanks to honesty of some of the parts suppliers

One Idea is to remove the dash where all the gauges are ( about 6 phillip screws) and double check the connections on the ignition switch. There are multiple connections, and if one is loose it may cause the fuel pump not to turn on. Myself and also Chris "V" had loose push on connectors and it caused the fuel pump not to turn on.

Thanks for that blast from the past ! (see she loves her man, or did she just want to get the D90 back to CT;-) Just to sum up what it was : "wrong gas cap , water got sucked in to the tank , being heavier than fuel it went to the bottom and directly into the fuel pump / injectors and the engine wouldn't fire with the 74 % water 23% fuel and 3 % peanut butter cup pond slime mixture. Thanks to Allen Dobbs and the rest of the guys who dedicated themselves to finding and fixing the problem. (You guys are the best)

Subject: [D90] sealants

Chris V. sez:
"....After pulling the tank and pump I found the filter clogged with black Permatex sealant....."

Chris and others:
There's no need to use RTV rubber as a gasket dressing, and as Chris (and many others) has demonstrated, it can be dangerous to do so. If that had been the oil pump that ingested a wad that came free from an oil pan or valve cover gasket, Chris could have been replacing something a lot more expensive than a fuel pump. Use RTV rubber only where you need to CREATE a gasket to fill a large gap. For gasket dressing and sealing metal to metal contact use Hylomar HPF. It's advantages are mani-fold.

- you use only enough to give a tacky surface. Almost no discernable thickness.
- truly oil and fuel PROOF All "colors" of RTV are loosened from metal surfaces by oil and fuel. It's just a matter of time.
- non hardening formula means gaskets release in one piece and can be re-used in an emergency. The Hylomar will still be there too, just re-distribute it evenly over the surface.
- In a thread-sealing application the high-tack, non hardening nature of the hylomar simultaneously promotes shake resistance and provides some anti-seize properties by sealing out air and moisture from threads.
- Hylomar has no ammonia fumes to damage sensitive parts.
- and my favorite, no drying time (how much is enough, I always wondered with RTV rubber). The tube states "Assemble parts and return to service immediately"
- Oh yeah, and since it's non-hardening, a tube lasts forever, no more frustration of finding half a tube that's "RTV'ed" in the tube due to a cracked or poorly sealed cap.

One more point. Bill Burke pointed out during Jay G.'s axle bustin' adventure in Moab, that RTV should never be used on axle flanges or stub axle mounting. The RTV will create some amount of a flexible gap between these high-bending-moment parts. Allowing flex where there should be none. Use only the (THIN!) paper gaskets with, at most a flange sealant. Hylomar is a good flange sealant, but Loctite-Permatex makes other products dedicated to that task. Most importantly - NO RTV!

Tdi Injector Pump Timing

Sent: Wednesday, November 29, 2000 8:50 AM
Subject: RE: [D90] 300 tdi timing (long)

the way to tell is:

Lean into the engine bay and remove the small triangle shaped cover plate that goes over the end of the FIP
you need a thick piece of bar, or a drill bit (can't remember the exact size, about 10~11mm) rotate the crank pulley until you can slide the drill bit into the groove on the FIP pulley (it should go in about 3/4 inch, when the FIP pulley is at the 12:00oclock position IN RELATION TO THE FIP (which is mounted at an angle to the engine remember!))

Crawl under your engine, remove the wading plug (if fitted) and look up into the hole (with a torch).
You should see the groove in the flywheel lined up with the hole on the bellhousing. if not, then get back up, remove the big drill bit from the FIP and rotate the crank another 180degrees. refit the big drill bit and go back under the vehicle.
Take a peek into the hole again, the groove should be lined up now. If it doesn't on either, then the cambelt timing is out.

SO......remove the cambelt cover plate,get someone to turn the crank (with a suitable sized socket on the end of the crankshaft, not by the starter motor!)
turn the crank until you see a groove in the flywheel line up with the center of the drain bung hole. (there is a proper LR tool to lock this into place,i made mine by getting another wading plug and drilling a 1/4inch hole through the center of it on a lathe, then get the same 1/4 inch drill, turn it around so the blunt end points in towards the flywheel and use this to lock the wheel. if you'r handy with a welder, a small dab of weld,a washer and a spring can be added to make it 'spring' into place and lock solid)

when this is lined up, the engine is at TDC. loosen the belt tensioner, remove the belt (make sure you refit it the same way round it came off) and turn the FIP until you can fit the 11mm drill bit into the slot. when both the FIP and the crank are locked into position like this, the belt is ready to refit.
First though, loosen, but don't remove, the three 10mm bolts that hold the FIP pulley in place. (the pulley has elongated holes so when the bolts are loose, you can turn the pulley a short way.
refit the belt onto all the pulleys and idlers, and 'wiggle' the FIP pulley until all the teeth on the pulley line up OK. tension the belt (15lb/ft off the top of my head! a 1/2 inch drive rachet will fit into the tensioner arm) nip up the FIP pulley bolts, remove BOTH locking pins (or drill bits) and then rotate the engine 2 turns on the crank pulley (with the rachet) and then re-fit the locking pins and double check that the belt has in fact lined up properly. as long as both of the pins can be fitted at the same time then all is OK (as the FIP turns at 1/2 crank speed,same as the camshaft on any engine, you may find that you have to move slightly the crank to get the bellhousing pin to pop in place)

And that is that! my old 200tdi ran with the FIP 180 degrees out once (my fault!!) and i ran it like this for about 6 months before the crankshaft broke in two!!! it did knock a little though!
