Fuel sender- 65 van

[mowogg]

The sender from the old tank was siezed on removal. After coating it with wd40 I took off the side plate to the internals and sprayed more wd40. The unit now moves freely and seems to work now. (resistance changes when moved).

The unit did not appear to have any seal to the internals. This would be in the tank so I would assume would flood with fuel. Is this correct?

It does not feel as if it should be like this.

Hi mowogg,
On my 1968 traveller I have a gasket that fits between the sender housing and the fuel tank, this stops any fuel sloshing out from that gap. If your question is that the part of the sender that is inside the tank needs any seals then it doesn't, on mine all the sender mechanism is exposed inside the tank with no issue. It's not a pretty sight if you take the sender out for repair after a few years but if mines anything to go by that's the design they chose to go with. If you require the gasket then ESM do them for a reasonable price..

Thanks for the reply. This is not the gasket I was attempting to describe.

The issue I have is the unit itself. once removed from the tank I took the plate off the side of the sender which was only half with 2 screws. Undebeath is the electrical switch but no gasket. This would be below the fuel level when the tank is full.

It would seem off that fuel could leak into an electric switch?

If you look at any for sale from any of the major suppliers and / or flea bay they are all the same. The sender is sealed into the tank with a cork gasket ( rubber now available) - I cut mine years ago from gasket card. One pole is the car body, the other is on the sender unit with a wire to the gauge. It does not seem to cause problems. It is important however that the float is not holed. If you have increased resistance with movement it would appear to be working.

Hi mowogg,
Ahh yes I see what you mean, that electrical circuitry is indeed exposed to the inside of the tank and thus the fuel. Mine doesn't contain a gasket or any seals, I will have a look at a spare I have nocking around but I would put my 2 cents on that "compartment" not being sealed and yes you are correct thinking that fuel could leak into the electrical circuitry. In terms of safety... god knows however mine is of the same condition as you describe. I'm more than happy for someone with greater knowledge to tell me otherwise as I would fix my own switch. I hope this is helpful
