Fuel Sending unit replacement Question

Just picked up a new Fuel sending unit for my rebuild and have a question, when using the rubber gasket on the top should i seal it with something (RTV-?) or is just the rubber seal good enough?
Also is there any calibration that I should do before I assemble it?
Thanks for any info.

I don't think its absolutely necessary, but it couldn't hurt either. I used a very thin coating of Permatex #2 (the black tar stuff). There isn't any calibration that I'm aware of, although I would check to be ery sure that the grounds are good.

If you want to be able to go back in without buying a new gasket. Do not use RTV. It is a thick gasket.

Gasket should be fine on it's own and there is no calibration needed.

NO rtv. Rubber gasket is A OK by itself.

No silicone here. Make sure you add a sending unit access hole to the bed of your project.

Thanks for all of the replies. Will install just the gasket, as I am replacing all of the hardware and sandblasting and painting everything, if I have to drop the tank down the road it should not be an issue. Thanks again, Jim

Jim, glad to hear you're going with the gasket only. I'll give you an example of what that silicone or rtv will do. I had my fuel pump replaced at a shop by a licensed mechanic. Later on, I was having trouble with the jeep shutting off while driving for a good hour or more. After sitting for a few hours, it would crank and run again. Decided to drop the tank and check out the pump. The mechanic put a tremendous amount of silicone around the hole for the sending unit. Silicone + Gasoline = Jelly. The jelly would get sucked up around the screen and stop fuel flow. After sitting, it would fall off and drop back to the bottom of the tank. Had a good handful in there. I wound up replacing it with a Bosch and did the work myself.

Wow That sounds like a mess, I will avoid the use of any additional sealant. Thanks again for all the replies
