i was wondering if there was any trick that anyone knows to get injectors to seal. i got my 80lb injectors in and just keyed the truck to try and prime the pump to see what kinda fuel pressure i was getting and it wasnt reading long story short i have 2 injectors on the drivers side leaking fuel off the fuel rail " top" side. i been trying to get them to seal but have been having trouble. didnt know if there were any tricks? i do know that the fuel rails dont sit at the same angle as the stockers but i would think that would cause the bottom end to leak if anything?

 

can you put some pictures up of the differance in angle.. and maybe you ripped a o ring putting them in

 

ya ill have to see if i can get some pictures later on. i have a few more o-rings so i can try swapping them out.

 

I had a leaking injector also when I switched to 80lbers due to a o ring ripping. I tried orielly's upper o ring kit they wouldn't work a tad bit too thick for the fuel rail( using stock fuel rails)

 

i cant remember what brand the o-rings are. what did you end up using? im using the 80lb injectors on a stock fuel rail and intake so since they are taller i got longer bolts but they dont seat on the way down on the intake manifold

 

Are you lubing them up before you put them in? Nobody likes a dry hole lmfao. I use some petroleum grease on the o rings before I put them in and don't have any issues.

 

Haha right.... but ya i used white lithium grease on the rings

 

You need the right size o-rings and a lot of lubrication. I just use regular motor oil, never have any issues.

 

I ended up calling FIC and ordering some extra

 

ill have to try both thanks guys.
