Rusted Fuel Sender

[AxtellZ]

where's the post??

You mean you can't remove the sending unit from the tank 'cause it's rusted in place?

I've removed my fuel tank and would like to disassemble the fuel level sender and assembly so I can better inspect the interior. Once apart, I'll set all aside for future work.

Problem is the send is well rusted to the tank. It has set in a pool of Kroils penetrant for hours with little success.

It appears a special tool may be needed to remove the sender. It is basically a circle with three notches or tabs at 12, 4 and 8 o'clock.

Any thoughts on the best way to remove?

Take a hammer and a scew driver. Tap the notches with the scew driver and hammer. If you are doing it right it will turn and come out.

Bill's got the idea. You may try a hardwood dowel, or soft metal like brass, etc, instead of a screwdriver.

1) less likely to destroy the retaining nut

2) less chance of sparks

Otherwise, in the odd chance you have a jewelers tool, as is used to remove watch casings etc- may help.

Good luck

What I found was that there seemed to be a lot of outward pressure against the lock ring by the big rubber o ring that is under the sender that seals it to the tank, as well as the rust. I had the tank shotblasted first and a friend push against the lock ring to release the o-ring pressure whilst I tapped the against one of the lock ring prongs with a flat blade screwdriver and hammer. It worked for me, but the lock ring is pretty flimsy and bent easily.

If you can get a replacement lock ring perhaps from Chloe it might be worth sacrificing it to remove the sender without damaging the tank/sender unit.

Hope it helps

The lock ring IS available and is priced quite cheaply, IMO.

After 30 years of exposure to fuel, and moisture, I would recommend replacing the sender unit as well. It's not real cheap, but not real expensive either. It's never going to be easier to put everything right than when you have the tank out of the car.

FWIW,
