IDI return line caps - aluminum 6061!

[Nero]

I have liked them so far. A bit hard to get past a few o rings, did cut a few and have to redo later... Once the engine is running.

No cut o-rings here but I did have a helluva time getting the fuel hose over the barb portion. 1/4" is a PITA and ordering the proper metric hose made a big difference, but of course the upside of the 1/4" is that the fit is so tight I doubt you need clamps.
