Fuel Tank neck. Hair line crack at base.
Hi Gents. Im going to drop my gas tank agian so that I can switch out the fuel pump. Last time I drop it I noticed a hairline crack at the base of the filler neck. What can I do to seal up this little crack other than getting a welding job?

Re: Fuel Tank neck. Hair line crack at base.
I bought a new tank to replace my 88s' corroded one caused by a hairline crack allowing moisture to enter and rust every thing up including the intake, FPR, fuel rail, and plugging up the FP, fuel filter, and fuel lines.
The filler neck for my tank has to be purchased separately and then soldered (not welded) on.
To make mine last longer I did the following:
First, I cut the filler neck after the bend, but clear of where it passes over the frame. There's a breather 1/2" line that attached to the inside of the 2" tube, this I also cut.
I used a couple of fuel resistant coupling hoses to connect the sections back together again.
Then, I use a 2-part 3M adhesive specifically for use with harsh chemicals including gasoline.
This allows the filler neck to flex while filling because to tell the truth I still catch myself leaning on the pump handle.

Sound like a plan. I live in the true Southern Cali. I mean deep. i live just 15 minutes north of Mexicali, Mexico. And yes, its still hot down here. There is no rust in the tank. I had just relaced the fuel tank and this will be the second time that I drop the tank in 3 months. Whats the name of the 2 part 3M?
