Thread: Boost gauge source line with no drilling

I'm thinking about running a thick fuel line hose, it was hard to break it, that should work right?

That sounds like overkill. Hmm, I wonder if I can get copper tubing smaller then what fridges use, then run that through the fender, with rubber hose to the manifold and gauge.

Basically use it as just a hardline for the fender, and stick to hose for the rest.

Ahh that could work, but probably is more expensive then then fuel line. I think I have plenty left over from my last projects

Thick hose is overkill.

Hardline would be AWESOME, if you could get the proper crush fittings for the gauge. I would just go with vacuum line, personally. Not as expensive as running copper hardline, and much more flexible so you don't have to go with more pipe, should you decide to move your gauge sometime.

Sure its overkill but if its cost effective... I think the rubber lines I used were deflecting and causing the reading to suffer. I'd like to get one of those silicone hose kits for when I re-boost.

fumes? c'mon now! how big a hole are we talking here guys!!!
drill a hole! besides the wire that occupys the hole, the carpet folds over it. and i dont know if your like me, but i run the windows down anyway.
dont have an exhaust leak and you'll be good. air comes through the vent too. fumes from a little tiny hole in the firwall arent going to add to much to the dirty air. you can get like a silly putty material to fill around the hole if the concern is that great....
just my $.02

agreed

Copper line I would advise against, ever tried bending it in tight places? And it easily kinks/rips. Run silicone hose.
