Fuel Sender

[Guest danny_samb]

Jusg filled the tank up and it appears to be weeping around the sender, dry the petrol off and it appears on top of the sender again, can't see where it's coming from no drips etc, only thing I can think of its not sealing properly and it's somehow getting on top of the sender

Have you got any photos? It could be a hairline crack in the metal pipes that come out of the sender. It could be, if you have used rubber pipe comming off the sender, that this pipe is not sealing or is not fuel grade.

 

Photos would help

I am using rubber fuel lines, they are marked as fuel grade, not damp around the pipes. I think it's coming up through the bolts

I bought sheets off cork and nitrile rubber off eBay and cut out a new gasket set.

Cork first then nitrile.

I also made 2 small metal bars to spread the clamping force between pairs of studs

Cork washers,hermatite then steel/brass washers under the fixing nut should cure this.

[Guest danny_samb]

Can I use, rubber o rings and locktite on the bolts going into the tank, or fibre washers, think the fuel is coming up the bolt not the seal around the sender

[fry61]

That's what I meant , sorry it wasn't clear, I had same problem seaing tank as the fixing bolts weren't spot-welded in;fuel was leaking up the threads.

[Guest danny_samb]

So you think what I have done might cure the problem, I'll re fill it later and see, if not I'll try fibre washers and locktite

Is the sender on the top of the tank ? ,can't see how fuel is getting past the mtg screws ,unless the tank is not sitting correctly in the chassis unless you have managed to fill the tank and the filler pipe to the brim i.e. over full ! [this does not happen on RH tanks in my experience] mower man

[Guest danny_samb]

The pipe was full too

[fry61]

If this car is going to IVA it may be requested " fill to brim" besides if it leaks "brim full & stationary" it will for sure leak when cornering. On my 2B tank the studs were not fixed or supplied;just the 4 fixing holes around the sender hole.

[Guest danny_samb]

Gauge reading full, but now no fuel spilling

[fry61]

Check it with fuel visible in the filler neck, all dry? then go have a beer or two!!

[Guest danny_samb]

Fuel in filler pipe, all dry now, beer o'clock

You must have a lot of patience to get a RH type tank that full ,what is your secret mower man
