Fuel tank sender position problem

[jasongray5]

My tank arrirved today:D
Looking good and all that, however, slight mis-communication with the guy who made it and the sender hole is in the side, about 3/4 of the way up, instead of in the top, The sender I have came with a rubbery thingy, do we think it will be fuel tight, or shall I move it to the top, and weld a plate over where the existing hole is?

Cheers Guys Jas

Have you a picture of the tank & sender unit Jas :)

It will be a lot easier to give you some sound advice if you do ;)

I guess if the sender and rubber ring are made to be used together & it was designed to be side mounted in an alloy tank, I can see no reason as to why it might leak .

The sender probably has a bendy arm that you can re-profile to give you the full range of movement & accurate reading :)

There ya go! Was planning on using self tappers to hold it in!

Should be okay, you can bend the sender arm for full travel. Be better than blanking the hole and cutting another in the top.

If in doubt you can get a tube of specific sealant for sealing the gaskets:

I use Dirko Grau which is great stuff.

if you cant get hold of that sealant you can use nitrile rubber as a gasket. Get it from a local gasket supplier.. Dead cheap

Another question. If you guys wouldnt mind, do you think sikaflexing the tank down would be ok? It cant actualy go anywhere as it is, with no fixings, as the rear tub and frame work holds it in place very neatly?
Edit to say, do you think the IVA man would shout???

Cheers, Jas

Doesn't sound like a good idea to me Jas. I think IVA man would much prefer tank straps! Also think about how you would ever get the tank out if you bonded it in.

Stand to be corrected of course!

Cheers

Yes, for the sake of a couple of straps i would securely fix it down. Not sure myself but would any spilled petrol act as a solvent and dissolve the Sikaflex.

yea sikaflex is not a good companion of petrol! Straps or mechanical fixings are a must! It will fail if you bond it down.. Its not a guaranteed fixing..
