injector return line questions
So I just finished a month long project of replacing my entire fuel system with fresh hoses, and new brass fittings to make it all work. Now I have come across a problem with my return caps leaking. 4 out of 8 of my injector caps are leaking. I had replaced the caps and hose, but didn't have all the o-rings (the kit was missing one set), so some of the o-rings were not replaced. Would the routing of the return hose fittings, or the 6-psi carter fuel pump cause the issue? or is it more likely to be just the o-rings?
I do have a full set of o-rings on the way. In addition to my question above, can anyone give me a good, cheap method of removing and replacing the o-rings? they were giving me a hell of a time when I replaced the ones I had.
also, if pictures would help, let me know.

well, the original problem of not wanting to start is resolved. after much fighting and pain, and failed starts, the old truck finally roared to life and stayed running! i still have the injector cap leaks, so thats still an issue. But i'm looking into having some new caps made at a local CNC shop. any ideas on material? i was thinking aluminum, but may have to use brass...

Check out this thread where a guy made Brass caps.

R&D IDI Performance has Billet Aluminum Fuel rails.

Mc Master- Carr is a good source for the O-Rings

That o-ring link is super helpful! I did see the brass cups article yesterday while searching for metal caps, and the r&d billing unit is awesome. But they are both out of my price range right now.
do you know if aluminum would work as an injector cap material?

The guy above that made the Brass caps, originally made a set out of Aluminum.
The guy he used to Aluminum weld the barbs in screwed the whole set up.

Go down to pg 5 post# 73, he states the cost is $160 for a set. This is back in 2010.

This is all I could find Googling around.
For that price, you might as well go with R&D IDI Performance Fuel Rails.

That's all I was able to find too. I don' even know if the guy who made the brass units is even still doing it... I may have to go with the r&d kit. But I'm a little weird, and I'm trying to avoid chrome and polished aluminum. Maybe they'll sell me an unpolished version of the rails for a little less money. Maybe. Well, guess I can only try.
