injector line size

[Cummin_un_glued]

i'm sure this has been discussed but I cant seem to pull up what i'm looking for in search.

whats everyones experiences when going from 093 to 120 lines. looking for same setup only change being line size.

i'm sure that timing will be retarded some as I had to add 2* when I went from 084 to 093 lines.

Seems that a lot of guys say there is no need for 120 lines also.

What is everyones take on this subject.

fwiw its a 13mm pump and i'm not turning it past 4500 rpm

I currently have .120 lines on the puller only because the pump builder recommended them. IMO if the truck is not gonna be a puller and turn some rpm .093 lines would be my choice

I have .093 lines on my 4 cylinder VE pump. I didn't really see any major differences, I just had to custom bend a set, so I went ahead and went with a little bigger line. But I'm only turning 3300rpm

Running .120 lines on our 3.0 truck. Was told that 650cc s of fuel was about the limit on the .093.

IIRC, Ron Allen ran .084" lines on his truck, which was 1100-1200 rwhp.
