. . You guys diagnosed my pressure in the fuel tank problem as leaking injector copper washers. . Which after a little more research I believe to be correct. .
. . Looked for new seals and found them rather pricey. . Found I could get new Bosch injectors (not rebuilt) with seals for $180. . So I bought them. .
. . Question is, , The seals I looked at have two O-rings and the copper washer. . The injectors however came with only one O-ring and the washer. . The one O-ring is the larger one at the top. . There is a center grove on the injector that looks like it should have a smaller O-ring. . Are there supposed to be one or two O-rings? ?

I have a set of new Edge injectors. They have a large O ring near the top and a groove below the large part of the injector body. No O ring in that groove.

pressure in the tank caused by injectors??

How so?
My injectors have only one line in and if there was anything pushing back through them itwould prevent fuel from squirting , make the whole thing not run.

There is more fuel going to the injectors that what the injector squirts into the engine. That overflow of fuel runs back to the tank via a line out the back of the head. If the injector isnt seating correctly then it can allow some of the cylinder pressure to also make it back to the tank and pressurize the fuel tank.
