Pickup started to miss. Found Injector leaking fuel out of the top of the nut. Why do they do this? This is the second one. Installed new Injectors a cpl weeks ago. It is tight. I unscrewed it and it looks perfect. ERRRRR. Getting frusterated one thing after another.

 

are you sure that the fuel is coming from the top of the nut ?

if so, the flared end of the line (under the top of the nut) may be split.

did you put new return line caps, o-rings, hoses, clamps ?

 

yes did the whole works. I drove it for a cpl weeks now. Started leaking on # 3 cylinder. I took it off today trying to get it to stop. Still leaks. I will try and get another one next week. Fuel is comeing out around the line around the nut.

 

At 1500 +/- psi a crack in the line would not be visible to the naked eye if it was just a weep. Did you reinstall all of the clamps back on the injector lines? Time for a new line!

 

Everything looked good for three weeks, and now it's leaking again. Different line this time.

 

Check the injector for a crack or flaw in the sealing area..........

 

I will pull the injector and check it out.
thanks
