Replacing the fuel sender unit

I am planning on changing out the fuel sender unit this weekend. I have read over jclay's write up (thank you for posting these great articles).

My only question so far is: Should I use any sealer on the rubber gasket? If yes, what kind?

I did not use any sealer on mine, and haven't had any problems.

No sealer is necessary. I don't think the seals are even rubber but some composite that is gasoline resistant although we often generically call them "rubber". When you tap in the ring by the tangs tap with a flat punch close to the ring so you bend them as little as possible. If the seals are deteriorated or too compressed, new ones might be a good idea.

The new unit came with a seal, so I was not planning on using the old one.

Just use the supplied seal.
And make sure your tank is empty ...

Hi,

Supplied seal only and check the rubber pipe as they tend to perish in modern fuels

I replaced the hose several years ago after it failed completely. Went from a small drip to gushing gas in only a few minutes. Luckily there was not a fire when it gave up.

Living in Arizona is great when you talk about rust free cars, but our hot dry climate is not good for anything rubber.

Use the NEWER fuel injection hoses.

It is always a nice feeling when it goes as expected.

Thanks for all the help.
