I have a 1/2 inch spacer on my engine (M4MC qjet, little dongle for the TH350, longer arm necessitates spacer) and the metal fuel line won't reach nor will it snake behind my HEI. Anyone have a source for the same type raw steel looking line? I hate the look of that green stuff at the parts store, and the rubber hose looks cheap, not to mention dangerous. Any help is appreciated.
I've also heard the Pontiac 301 used a very similar fuel line setup... anyone have experience with that?
Inline tube should have something close. I believe Mark at Quadrajet Power has a braided line setup for Quadrajet available
I have always gone to my local auto parts store and purchased the tubing the same as I would purchase brake line tubing with the fittings on each end. Then I use my tubing benders to shape the routing of the tube. If the length turns out a little long, just cut and re-flare. Marv.
Sorry, I grabbed the wrong size line. You will need a 3/8” and it will have the correct fitting on each end.
If you are not stuck on the originality of a steel line, an AN fitting braided line works better, and seals easier, a lot easier. All you need is a conversion fitting on each side, pump and carburetor. What you need is a 5/8-18 inverted flare to -6AN adapter, like this, https://www.summitracing.com/parts/sum-220667b/overview/ One screws into the fuel pump, one goes into the filter housing of the Q-jet, then just make a braided line.
Summit Racing sells replacement steel fuel lines...though sometimes they can be found on ebay/craigslist. If you get a steel replacement line, get an insulation sleeve/non-adhesive vinyl wrap to isolate it from heat and vapor lock.
That green crap just comes off with a bench grinder with a wire wheel on it...if that's why your parts store sells. Zip it off and then bend the line accordingly. Clear coat afterwards.
