Looks sweet.
Make sure you de-burr the caps of any sharp edges before installation. Mine have lasted 100k with one change of the o ringsi have been curious on these fuel return lines and seriously considering it. i have spent $240 in new caps and o rings in the last year. most i have gotten a refund or exchanged on some. i have tried stock and over sized o rings to seal. stock work best but give it 5 to 10k miles and its leaking and not a small amount either. loosing 3 to 4 gallons on a 20 gallon tank. fix it and back at it again. injectors are new. old injectors had the same problem. i have worked on idis if it has original caps and o rings just replace the o rings or else they will leak and be a constant problem. i oil the orings before installing which helps. bigest problems is the quality of plastic on new caps. they do not handle well with cold wetaher. srping and fall is the worse for leaks as temperatures are changing. i got 3 new leaks that will have to be addressed. i have put over 100k miles on this in the last year.
if these metal solid lines work i would be interested. anything is better then these caps and o rings.
I used the cheap caps once. casting flash all up in the ID, but after some file work, it sealedJust use high temp grease. I use the cheapest caps possible just to prove a point - it does not matter. Use viton O-rings, grease them up and call it good.
Did you end up plugging any of the ports on the rails? There’s a few places on mine there was no way a hose was attaching therelittle update.
the rails have been holding well after a few heat cycles,
but I did try to get to my valve covers and decided to modify the rails.
now I can get to the bolts again.
