Hi,
I'm not a drag racer, but, what I've learned from guys it will "not pass" tech inspection. I'm don't know the reason though. Perhaps, a "voice of reason" will ring in.....

no you cannot have it mounted above the transmission. I didnt pass tech for that reason years ago.

i believe the NHRA prohibits fuel lines from crossing the bellhousing area to reduce the chance of blown flywheel/flexplate cutting fuel lines

The very fist step is to choose a proper hose size. 3/8 hose is what I was told to run and is currently what Im running now. So that would be the same as a 6/16th or -6AN fitting. Is this an acceptable size?

The aeroquip fuel line looks great but can I run any -6an fitting with it or are there some brands that must be avoided? are the summit brand an fittings okay to use?

Thanks

-Gun

Thanks! A very good reason.

Line size depends on the power of the engine and it's efficiency and delivery pressure.

-6 is fine for most street engine carb setups.

...and besides, it's all about delivery at WOT, wherein, line size and gph matter?
How many of us on the street live in the "WOT" zone, anymore.

Except if you go wot getting on a road and run out of fuel, then your engine could get destroyed. 1 lean out at full power on a high performance engine could be all it takes.

While I agree there can be a grenade effect, my preface is based on the GPH fuel consumption of a given engine and it's displacement. Given, a normal street prepared "hot" engine, they ain't run'n out of fuel at 6500Rs. Unless they are big cubes running 3/16" lines and very well prepared. Most fuel pumps would shut them down.

It depends on the setup. A 600hp turbo engine consumes substantially more fuel than a 600hp n/a engine. RPM doesn't matter, only power and bsfc.
