I put new glow plugs in my truck and I hit one of the rubber return fuel diesel lines now the plastic caps are all leaking I put new orings on them and now they are leaking worse there are no breaks they just dont seem to be sealing tight enough is there a secret to these. I am losing fuel bad about 1 1/2 quarts on a 20 mile drive. thanks Aaron

the caps are probably warn and need to be replaced. are you sure the caps are all the way down?

 

[Reefdiver72]

Do they snap in? I pushed them down but they are still leaking out the bottom I see there is a place for the oring to fit I think they are I guess I will see about ordering a set of caps tommorow thanks.

First thing to check, is that they snap-down into place. If not, there's nothing for the O-rings to seal against. It would be like not having any O-rings in there at all.

 

[EMD_DRIVER]

This may be a stupid question, but did you put two O-rings on each injector?

 

[Reefdiver72]

yes I put 2 of them on I will see if they snap tomorow I dont remember them snapping It kinda sucks 2 of them didnt leak before I tried to fix the first one.

 

[tractorman86]

they should almost touch that flat surface below them. push them down with a clean 1/2" deepwell socket then tighten the inj line

Yep deep socket and a small hammer will seat them on place. Also, vaseline helps a lot.

i use oil to lube the o rings for the caps to go over them. i also used oversized o rings, and risked craking the caps, but they didnt. its never been dryer.

Long time no see reef. I just had the same problem a while ago, messed with one then the ones beside started to leak. Make sure yo use plenty of lube so the o-rings do not roll down when the cap is shoved on. I used my original caps. I see the kits on e-bay every now and then if you would want to buy a whole kit. Also where did you get the o-rings at? I've heard of some recalls on rubber products like valve stems and o-rings on certain dates lately. My wife had to get her valve stems replaced on her 1 year old car because of cracked valve stems. China made products

what are they called I broke one now I am down and back to the car it sucks in traffic in my truck everyone get the heck out of my way I had some ones off my other motor but there a little diffrent and it leaked worse then the broken set so I would say they are wore out also. But i need to no what they are actually called. Thanks nice to hear form you to forcefed.

Another name for the fuel return caps is return bonnets, that's what they're called here in OK.

Dumb question how hard would it be to use stainless braided hose for return lines and even perhaps fuel lines it would really dress up an engine compartment nicely just throwing it out there for when i do my rebuild
