ive been having problems with my fuel injectors leaking. ive been changing the orings. its always one thing or another and i have to take it apart and put it back together... one always leaks. anyone had this prob, what am i doing wrong? i think the fuel rail is bent so i bought another one im going to put it on tomarrow.

 

are you sure he O-rings where installed properly?

I had that problem with my old runner, pinched the O-ring and it sprayed fuel everywhere

 

im pretty sure im putting them in right but it is leaking...

 

you positive it's the connection at the fuel rail that's leaking and not at the intake manifold?

4 or 6 cyl?

 

is it leaking from where the injectors attach to the rail? was it leaking before you took them out?

 

its the high pressure side (fuel rail) and its a 4cyl

 

i changed the head gasket after the truck sat for a little over a year. when i got it back together the coolant ports had rusted and i needed to replace the manifold so after nessing around with that for a while i finally got the truck running and this is happening iver taken ihe injecton apart atleast 6 or 7 times now but i have replaced the orings all i can theink is that the fuel rail is warped or something so i got a new fuel rail well see tomarrow i guess

 

ok, hang on a sec here... there's several spots the fuel rail could possibly develope a leak... injectors, inlet line, pressure regulator, and the line going up to the cold start valve...


my dirty motor, but it get's the point accross...




so you can pinpoint exactly where the leak is springing from?

has the leak sprung in the same spot every time, or is it jumping around?



unless of coarse somehow the rail has a crack???

 

the leak is where the injectors go into the fuel rail i have 2 different fuel rails and on one its on the no. 2 injector and on the other it seems to be on the no. 1 and 3. i got a new fuel rail today and im going to put it in tomarrow

 

oh, ok, well if it's constant as to where they keep leaking, then you probably just have some fauty rails...

good luck with the new rail install; let us know how it turns out!

 

turned out to be the fuel rails. got a new rail and changed the gromets and o rings and the leaks stopped
