ok the pump works, the fuel bowls are not stuck, no pressure in the fuel tank, clean fuel filter, lines are clear and not twisted. Oh and the fuel pump works ALL THE TIME??

So the tank is all what´s left.

Looked up around the sending unit and the gas line got pinched on the frame when I put the gas tank back up. Dropped the tank enough to get the line free. Just took her around the block and let it run for about 20 minutes. That had to be it. Keeping my fingers crossed she fires up tomorrow! Thanks so much for everyone's input... couldn't have done it without ya'll.

Fuel Problems

I had a similar problem with a Triumph TR-6. Car would run great then all of a sudden either shut down or sputter with no power. I tried everything and nothing worked until I discovered whoever worked on the fuel system before I had it used a gasket sealer that was not "gas compatible" on the sending unit. The gas breaks down the non gas compatible gasket sealer into small globs which then floats around in the tank. Eventually they find their way to the fuel line and or filter and plug it up. Sometimes they will break loose and the car would run great again, then stop or sputter due to clogging. I fixed it by removing the tank, removing the sending unit, cleaning everything including all the old gasket sealer. I reassembled using something like Permatex® Indian Head® Gasket Shellac Compound including the fuel line connections. Hadn't had a problem since.

There is a divot in the frame crossmember on the side where the gas line has to run or it will pinch off. it gets lots of us.
