Question about BE Gas Tank

Has anyone seen what the inside of the BE fuel tank looks like? On mine, the fuel line connects partway up the side of the tank, where I assume the fitting attaches to an internal pipe that goes to the bottom of the tank. I think that internal pipe must be loose as my electric fuel punp starts to draw air like the tank is empty when it still has several gallons of gas in the tank. If I jack the back of the car up a bit, the fuel flows fine. I'd appreciate it if anyone could comment on how the plumbing is arranged inside the tank. Not looking forward to pulling the tank off again.

Thanks!

Mike,
I have a early ('63) Mark II gas tank..I would guess they are similar, sure sounds like it. Its off right now so I'll get you a picture tomorrow.
 
I have not been inside, but have the same on the outy.

Mike couldn't get a good picture..there is a plastic strainer I can see from the sending unit opening, but that is all I can see. I can't see the tube because its behind a baffle plate. Sorry, can't help with how the tube looks.
 
Update on BE gas tank

Ended up having to pull the tank and found the pipe to the in-tank strainer to be loose in it's fitting. When the gas level fell below the fitting, the electric fuel pump began to draw air, eventually just cavitating. Of course, to actually see this, I had to cut an access hole in the top of the tank. To seal up the air leak, I worked JB weld into the fitting and will weld a patch over the hole tomorrow.

What caused the problem? The fuel line going into the tank had been repaired in the past with JB Weld to deal with a leak due to stripped threads on the fuel line nut. The tank did not leak, but I'm betting that the fuel line nut just was not tight enough to seal the in-tank line.

Yes I did thoroughly air the tank out before making sparks! Nothing like working on a gas tank in the Texas sun.

You might have to do this.

Re: Update on BE gas tank

A plate tapped on the inside and a plate with 32 screws on the outside with a gasket. I went in and got rid of the strainer in the tank before I used red kote on the inside. I put in a cleanable inline filter before the fuel pump.
 
Re: Update on BE gas tank

The tapped plate is a good idea. I used sheet metal screws to hold the patch plate in plane on my fuel tank while I welded it. I did a pressure check using my handy pump up garden sprayer and found I still had pinhole leaks through my crappy weld, so sealed them up with a layer of JB Weld. I should be able to put the tank back on the BE tomorrow afternoon.
 
Re: Update on BE gas tank

If the JB doesn't do well then Loctite makes a special green type just for weld porosities and such that works well. I put on the plate with all those SS machine screws in case I ever needed to gt back in there again. The hole is not as big as the patch plate and I drilled holes through the tank as well. Holding that taped out piece on the inside was a bear but the gasket and all went easy. I just could not live with the fact that the redkote might have sealed part of that thing up. I had to get in there and see and remove it.
