Hello: I have two GTX DI's and they are doing the same thing. They idle for awhile then die as not getting enough fuel. I put a presure tester on both and found that, 1. When putting in the key the pressure goes to about 27 psi. 2.. Cranking presure is around 85 psi. 4. starting presure is 106 psi for about 30 seconds then the presure begins to drop until it get to about 80 psi then dies. I let it sit for minute or two then refire with the same results. Can anyone tell me the problem?. Also is there a fast and easy way of taking off the clamps on the fuel lines with out the tools mentioned in the book. Thank you
