That looks to be similar to the early style sender with 5 or 6 screws attaching it to the tank. Removing the screws and carefully prying up on the sender will remove it. Be ginger with it as if you deform the sender or the tank top you may create a leak that will be difficult to seal.

Is this a driver or a longer term project? If it is a driver I would have some gasket material handy and tools to make a new gasket. Either way it is likely you will need a new gasket for reassembly. If you have time you may find that the gasket is a common one.

Other than that I recommend blowing all dirt and debris away followed by scrubbing with soap and water to clean it as well as possible. Getting it nice and clean around the sender will prevent any debris from getting into the tank when you pull it.

Re: Gas tank help

Thanx I’ve never seen a sender with 3 tubes, I know one is main feed, and he is for the vent, I don’t know about the last one even though it’s capped

Re: Gas tank help

It being an aftermarket tank it may have enough ports to be legally installed in California back in the day. That would have meant it would have had to tie into the emissions system.

So one supply to fuel pump, one return from fuel pump and one vent line to the vent canister.

Re: Gas tank help

I have a dealer installed tank on mine with the universal five screw. I ended up keeping the pickup and flange. I bought 0-90 ohm universal sending unit on amazon for cheap. It took some garage engineering, but I got it hooked up. It may not be the most accurate, but it reads about 7/8 when full and 1/4 when empty.

Pics are the before, after, and gauge.
