I'm looking for some advice on the way I currently have my injector return lines set up.
I purchased some Peterson CNC aluminum return caps that I purchased from Classic Diesel Designs. First impression is that the quality is very good. My question comes from the size of the fuel barbs, which use 1/4" return hose connections. My truck originally had the factory-style setup with 3/8" return hose, so I had to use reducers to connect everything to the factory brass return manifold (see attached picture).
My first attempt used aluminum 3/8" to 1/4" reducers from Summit Racing, but I could never get them to seal completely and they would seep fuel. I replaced them with plastic reducers from O'Reilly's, and so far they have not leaked.
My concern is long-term reliability. I'm wondering what the best solution is:
1. Leave the plastic reducers in place and run them until they become a problem
2. Replace the brass return manifold/barb fittings with 1/4" barbs so the entire return system is 1/4" and remove the reducers altogether
3. Stretch 3/8" fuel hose over the Peterson CNC return cap barbs
Has anyone else run Peterson CNC caps with the factory return manifold? If so, how did you handle the hose size difference, and what has held up the best over time?
