lb7 injector and leak problem

[duravette]

so this week i just got done replacing all the injectors in a lb7 and i finished it and started it up and it ran like a charm. I let it idle for about 30 minutes and as soon at i put it in gear to test drive it, it started leaking fuel and died on me in about 100 feet. i searched up and down for where the leak is but i cant find it, its seems to be on the driver side somewhere in the back of the motor. the truck wont run it just cranks over.

could be the feed lines did you make sure they were clean and tighten them down even not one end at once then the other?

 

[zlonsway]

Could it be leaking from the injector return on the back of the driver side head?

 

[duravette]

yeah both ends are tight, but now that you say that it could be leaking from the return.

 

[Evan@InglewoodTrans]

If it's leaking from the return it should still run.

 

[duravette]

yeah then that must not be it, it just cranks over without firing.

 

[Evan@InglewoodTrans]

How bad is it leaking fuel?

 

[duravette]

when i crank over on it, there is maybe a drip every couple seconds. but when i drove it and it started leaking there was a small steady line.

Driver side return line is on the back of the head. Check that because if thats leaking then you are getting air.
