I installed new return lines a couple weeks ago on my '93 F250 N/A and it's developed a leak at the # 1 injector. It's not coming from under the cap like it would be if it were the O rings and I used new O rings and lubricated them good before I put the caps back on. It looks to be coming from where the two lines go on to the nipples of the #1 injector cap. Should I cut new sections of line and replace those two pieces or maybe try some different clamps that will hold tighter?

 

you got your kit from pensacola diesel.i recognize that leaky fuel line anywhere lol been there done that.

you can hit up Russ too.i think he sells the Diapco kits,and i know he has the vitons as well.

 

Actually I got it from Accurate Diesel in Michigan on Ebay. So you think I need to just replace the whole kit?

 

the kit i got from my local parts store worked great, IIRC made by standard ( i could be wrong, its been a couple months and a few whiskeys), but hose clamps were green and it worked great. store currently bears the name "auto value" and has previously had the carquest and parts-plus names.

 

I had to replace one of my lines last week. It was soaked with fuel as well. I may have cut that line a mm or two too short and it was not sealing well or I could have upset it when swapping my #4 injector. I cut the new line a little longer and it is working fine so far.

 

I have some line left over from a couple of kits so I'll try cutting a new line just a hair longer and see how that works.
