Gas Tank Fills EXTREAMLY slow

I purchased an aftermarket poly gas tank for my 86 CJ-7 after the OEM metal one started to get several pin holes rusting through. Ever since I put it in I can hardly fill the tank with gas. Everytime I try and fill it I have to barely squeeze the pump handle so gas just trickles out. I have pulled it out 2 times and nothing is blocking the lines to the tank and they are not pinched off. The only thing I can think is the neck of the inlet is thicker on the poly tank than on the metal tank, and its creating back flow that stops the pump. Anyone else have this problem and found a way to solve it? [img]images/graemlins/cussing.gif[/img]

You checked the vent hose back to the filler, too. Right?

It makes sense that the hole in the fittings is smaller, because plastic has to be thicker than steel, but it has to fit the same hose, unless you use a metal adapter.

drop the tank, attempt to fill it on the ground, with no hoses or anything attached, see what happens. hate to say it, i know how much of a pain it is to drop the tank. might just be a different shape of the fillerneck, causing the gas to splash some funny angle. good luck.

Have you tried pulling the gas dispenser about 1/3 to 1/2 way out? My TJ will shut off the pump everytime if I put the dispenser all the way in. Back it out a little and it fills just fine. HTH
