In Tank Fuel Valve Leak
 

First off, at the bottom of the tank, is that a valve or a low volume pump?

Second dose it leak from its housing?
(I resealed the gasket 2 weeks ago and it still leaks)

Is replacement the fix?

looks like #1 with wires

It does leak if the seal has never been replaced.

When you pull the intank pump, be careful not to strip it out, it will ruin the tank.

It is possible to salvage the tank should you find that the threaded insert spins in the tank opening before your intank pump spins loose. My intank pump was corroded to the threaded insert and I ended up pulling both out as the pump with insert would just spin in the tank.

I was able to remove the insert from the pump once out and salvaged th insert. I used JB Weld to reinstall the insert into the tank as have a few others and installed a new pump. Tank has been holding fuel leak free for two months.

Its a pump if it has wires. Were originally installed for hot climates, which I suspect is not your case. My car has only the external pump, and it survived 10 years in 120F in Saudi. I suggest you replace it with item 2 from the parts picture (inlet filter), and tape up the wire leads, as was done by the factory when the intank pump was not fitted - stiil there in mine. My wrench recommended anti-seize on the threads, AND only tighten JUST enough to not leak, not much more than hand tight. I am one who spun the insert in the tank trying to remove a failed filter, gave up, and successfully sealed it with PC11. I gave the tank to another guy who pulled the insert, removed the filter, and refitted the insert successfully.

I've stripped a couple of them out replacing the in-tank pump also. It sucks.

Most pumps do that - suck that is....Very good. I usually use 'There's no such thing as gravity - the earth sucks'.
