I followed psfred's procedure and the leaks stopped. However, I had a problem afterwards with the fuel line tubing going to the injectors. It seems, that I could not get some of them to seal on the injectors. Less than 10 miles after the pressure valve seals were replaced, the #2 fuel line tubing started leaking (squirting) on the top of the injector. I tried to tighten the the 14 mm nut but no luck. So far, I had to replace the #1, #2 and #4 fuel line tubing at about $32 a piece. I imagine, I will have to replace the rest at some time soon. Any similar experience out there?

Thanks,
