Fuel tank leak at sender, valiant pt 520

[Al.]

I have found a leak at the joint between the fuel tank and send unit, but it seems that someone has played with this in the past, the sender has been changed, and the hole pattern was wrong, so they have drilled the senders plastic surround, and made a gasket,

So I have to two fold problem.

First are there different 5 hole pattern as the holes in the tank are closer than the wema that's been fitted.

Does anyone know what the part numbers are for a new sender for the valiant pt 520.

Thanks

Unfortunately i don't know the pattern in a valiant, but yes, there are different patterns.
On my project flipper had the SAE5 Ø54mm pattern(VDO) and found out that there was different patterns around, not fitting the SAE5 holes.
