Just fitted a new fuel sender to my LR90.
Decided it time to fill the tank, went to Tesco as I had 10p/ltr discount so brimmed it....Smelt diesel all the way home so assumed i'd overfilled. Parked on the drive, which is sloping and heard what i thought was water. Investigation shows it Diesel coming out the fuel sender!!!!!
Anyone any idea how i can make a better seal? I bought a new rubber seal and fixing ring, cleaned the rim of the tank all before fitting.

Does Diesel eat in to tarmac like oil will?
 
Warm the rubber ring in hot water and put a smear of Vaseline on the tank and on the sender faces before assembly.

I used a pinch bar with a block of wood as a pivot to turn and tighten the cam lock, and have not lost a drop since.

Yes, doozil does eat tarmac!
 
Is it a TD5? The Defender TD5 has the pump mounting hole recesses well below the top of the tank so it's quite a bit below the fuel level when the tank is full. Mine used to do this, so whenever I filled the tank I used to drive it a lot straight away so I'd get the benefit of at least some of the fuel before it leaked out. The solution was a new rubber ring correctly seated (as the old one was all rucked up and creased) and gasket sealant on both sides of the rubbery ring. The pump is held on by a pressed metal ring rather like a jam jar lid with threads pressed into it and notches pressed in the top that are supposed to engage with an expensive Land Rover tool. You can manage by tapping it around with a drift and hammer though.
 
Just looked at Buz's profile. Doesn't say anything about a TD5 so that's not relevant. Gasket sealant isn't model specific though. Land Rovers love gasket sealant, just as much now as they did in 1948.
 
Thanks for the info, it was originally a petrol 90 but has since had a 200 Disco unit installed. I'm assuming the fuel tank would be the same for both?

Now debating wether to try the vaseline option or go for the gasket sealer.....decisions decisions
 
I think the 200 is a bit different so I don't know what yours would look like. However, you can't go wrong with gasket sealant, especially if it says 'fuel proof' on it.
 
It sounds like it seals the same way, with the small metal 'Jam Jar' like ring, except i don't think mine has threads on the side, it just turns through about 45 degrees and holds it with some lugs.

Yep, think i'll go get some gasket sealant :)
 
Well oil beef hooked........

Local garage didn't have any gasket sealer for fuel line use so decided to try the old vaseline...luckily I had one without sand in it :eek:

In the sunlight, looking at the fastening ring i noticed one of the lips on the tank wasn't bent over enough and the fastening ring wasn't tight to the sender, hence the leak :doh:
Took it all apart, cleaned, vaselined and lugs all checked/fixed, put it back together and all now looks ok :)
 
The lugs can be tightened by judicial use of a hammer and drift, and if the rubber ring is warmed you will get a good seal. The vaseline is so that the cam lock is lubricated as it turns.

Thats just what I did :5bcheers2:

Been out to have a look this morning, parked it on my drive that has a good slope on it, no not the Clarkson type! and everything seems to be diesel tight.....jobs a good un......time to move on to the next one now :D
 
I've got a split in the copper feed pipe where it joins the sender. I've just covered it in tigerseal and then im going to smear Vaseline over that. Probably not a long term fix, hoping to get it re soldered at some point but should do for now...
 
Does it come out straight or does it have a bend about 1 1/2 inches from the plate?

If it is straight, have you thought about using some 3/8 hose heated up in boiling water and then slid over the end and then secured in place with a couple of Jubilee clips?
 
I'll have a check in a minute but that's a good idea! The leak is causing my engine to splutter and die randomly due to drawing in masses of air!

Thats how mine is connected, it gives it a bit of flexibility as well :)
 
Isn't it nice to know that there are still some of us Old Gimmers who can still modify whatever is at hand to keep their Landies going, and possibly more importantly, to be able to pass those tips on to the next generations! ;) ;)

My throttle return spring was a posties lacky band for many a year! ;)
 
Excuse me, us Old Gimmers!! i didn't realise 49 was that old, well, not now i've reached it!

Yep, thats another good thing about forums, someone usually knows more than one way of fixing things!
