Re: Fuel line sizes and pumps required
I run 3/8" from the tank to a holley blue, with a similar engine to yours, also with a nitrous system running off the same supply line and have had no fuel supply problems with the reg set to just under 8psi.
I was considering running 1/2" and after asking some blokes more in the know, they asked me "WHY?"
i was running a aftermarket mechanical which was fine, and then a stock replacment goss fuel pump, and it just used to run out of puff after nailing it through all the gears.
at least go better mechanical pump, and probably 3/8", but you'll love having a holley blue (except for the noise)
