injector leaks 1, 3, 4
Hi, just noticed some leaks in the visible threads on injectors 1, 3, and 4.
Don't think they were there until a couple of days ago, but is this something that can likely be solved by loosening the injector line and gently tightening the top portion of the injector? Reverendxlt

I will say that I replaced my fuel return hose that runs from the spin on filter back to the tank return line, and this reduced the leak at the injector by 90%. The hose that was on there was not the original and I think was to small. I took the OEM one off my parts car (it should bubble out in the middle). Point is I think to much pressure on the return line and those things will leak. I havn't tried to tighted the injector. Let me know if that works. It's still weeping a little but much better than before!

definitely check and or replace the rubber fuel return hoses, they are 99% of the time the cause of fuel leaks on the motor.
if they are new, or you are sure the leaks are not coming from there, pull the hard lines and the soft lines, and try to "slightly" tighten the injector body. you could have bad heat shields, or bad PC seals... good luck. John
