I'm pretty aggravated with myself right now. I ordered the L78 pre-bent lines for the fuel feed from the pump to the carb. Z28 lines showed up... So I figured I'd just bend the long one because it's pretty straight. That's when I noticed the feeds to the float bowls from the Y block are 5/16". Bah... I wanted the basically stock look, but I want to run 3/8" the whole way. 5/16" would probably be fine for the two branches, but then I'd need different adapters also.
Does anyone know of a stock looking brass fuel line Y block that is 3/8" in and out? For now I'm having to run a Mallory aluminum Y block and I'm custom bending all three lines.
Thanks Kevin. That's the same spec as what I have though. 3/8" inlet with two 5/16" outlets. I want 3/8" for all three.
Rick, I hear what you're saying and you're probably right, but I'm running ~550 hp/550 ftlb right now which will increase over time. Our specs are pretty close by the looks of it, but I'd feel more comfortable with 3/8" all the way around. That's why basic fuel logs are generally all 3/8". I run my car pretty hard when I'm playing. I'll end up at the 1/4 mile with it.
I had a problem with the 5/16 fittings weaking. Both at the float and at the y-block. I was able to get 3/8's lines and y-block from Steve's Camaro's in San Bruno. Steve's is no longer in business but the 3/8 setup must be out there. It's a common problem with repo parts.
At onetime I found a guy on eBay that sold the 3/8x3/8x3/8 with the lines to the carb as well. I cannot find anyone that has these pre bent, anybody know where to find them?
Hey Jeff. I looked pretty extensively and couldn't find anything. It was relatively easy to bend up the 3/8" brake line and flare the steel fittings. I needed the fitting that we talked about here as well as a 3/8" npt inverted flare female to 3/8" npt male fitting which was as tough to track down as the T fitting in this thread. I needed that one to go from the fuel line I bent to my fuel pressure regulator which I have mounted in place of my mechanical fuel pump.
The only thing I would like to have done better was the bend from the fitting to the float bowls. A longer curve would have been better, but without filling the tube with sand and coming up with a form to bend it around it wasn't easily happening. I'm happy with how it came out. Now to strip all that foolish looking powder coat off the body and bowls...
