Fuel sender leaking - Anyone else suffered the problem

[The Moosehunter]

Presumeably it's just a seal / gasket perished or heaven forbid a crack in the welding

Just wondered if anyone else has been there done that or whether I'm gonna have to wing it on a prayer

Gotta get rid of an almose full load of fuel first. What a shame

It may have to wait until the outrigger works in January, when it may be prudent to remove the tank, as I'm sure I read somewhere that leaky fuel tanks and welding don't necessarily go together well

Any tips ? ( useful ones please )

Knew I could rely on you Tony

You sorting any runs at Xmas ? Fancy a track day in January ? See how well yours goes round corners. Just follow the smell of petrol and bits of flaky outrigger strewn across the track

Had to do mine on a 99 chimera, the sender is in the top of the tank. There is a rubber 'O' gasket between sender base and the tank mine had a few cracks and made it really stink of fuel. You sould beable to change it now as it right on the top flat of the tank. I think the gasket came from racing green as none of the motor factors were interested in just suppling it on it's own.

I had this problem on the Griff when I bought it. Simple job once you have the new gasket. Several of the online TVR sites have it but don't want to promote one over the others as they are all good! But email me if you have problems finding it.

No need to drain the tank as it's on the top O/S of the tank and easily accessible. The one thing to point out though is that the 5 holes are NOT equidistant although they may appear to be. So before you refit hold the fuel sender base and gasket to the light and twist the gasket until all holes exactly line up. If you don't, then it will seal for a while but then go again.

Thanks for your replies

Unless I am very much mistaken my sender is on the nearside of my tank halfway up ( where the leak is coming from )

If it's not the sender then theres something else there leaking. What ever it is its bolted onto the side of the tank

I will stick my head in there and find out more

If its an early car - I'm guessing here - but I understand they are closely related to the V8S with a number of components.
The V8S & S has a side mounted sender unit and one of the S guys has found that its a landrover rubber seal & retaining ring Part numbers ARA 1501 and ARA 1502, cost about £3 for both.

Finally got round to poking about at my moist carpet area

My sender is certainly mounted on the n/side. The car is a '92 so could well be the V8S hybrid you refer to





Close up as best I can of the unit itself





Need to sort this but have a track day at Bedford in 2 weeks so don't want to tempt fate and pull it apart before then and find I have a deeper routed problem. the leak is minor at the moment

Off the road soon after that for the dreaded DIY outrigger replacement saga. (Best sort before then as welding and fuel vapour do not mix very well)

Moosehunter, precats have the sender on the side as yours does. I could never believe that it was possible to remove the sender with the tank in situ; it has the float arm attached to it as well don't forget. Nontheless I'm sure someone claimed to have done it (it may even have been our very own AnthonyJ).

Cheers for the info

This was my thinking and the very reason I am putting this process off til after the track day, and then I'll remove the tank as the first job prior to starting the outrigger welding.

Anyone happen to know the pre-cat part numbers ?

Cheers
