-10 feed and -8 return is huge. I’ve done 1300whp+ on cars I’ve built on single -8 feed and -6 return. Just a heads up. It tucks under the car nicer and it’s cheaper.

And realistically you’ll need about 15 feet of each.

 

Hello, to confirm the 1300WHP cars you done on -8 Feed were on E85? I'm getting close to finalizing my fuel setup from my surge tank to the engine.

Thanks

 

Yes sir E85 cars. 3 Hellcat pumps on the 1300whp car and multiple 1100-1200whp setups on 2 pumps, all using single -8 feed and -6 return. I’m building a 1500+whp Supra right now and am using single -10 for that one.

 

Thanks for the input. I'm sure a single -8 feed will serve me well for a long time on my 62mm stock block GTE VVTI lol

 

Lol yeah you’ll be fine 👍

 

could having too big of a fuel line bad? just wondering. since im only aiming to max out my 6466 but planning to upgrade to something 1k++ Hp

 

Too big means more expense on fittings, usually by about 30% from my findings. I'm currently running -10AN feed and -8AN return for my 1000rwhp+ build. I can tell you now, trying to run a -10AN teflon line over the diff without it kinking is almost impossible.

I'm purchasing a PHR Y block with a -10 to 2x -8's. The -10AN runs to just in front of the diff where I split it into two -8's that bolt up to the -8's on the PHR pump hanger.

You could potentially use fittings to help turn the corners without bending...

Hey man, I've been running a single -10 feed and -8 return for years, (massive, massive overkill for my set up ) and I never managed to kink the line over the diff at all. It can be done. Sorry I don't have photos to share unfortunately but I am currently pissing the braided lines off and going -10 feed, -8 return anodised hard lines.

 

The bend in the shorter length of pipe here is -10AN, this section of tube has been kinked just getting around this radius. It's nice to have the -10AN for the filter and the Y block connection to the fuel rail... If you need the flow -10 provides, perhaps look at splitting it like I have at the rear to -8's to save yourself the hassle.

 

Sent you a pm about something since we have almost the same fuel line setup

 

I'd caution against using any more fittings than necessary in a fuel line, as each additional connection is a potential leak / failure point. Make sure you can see them, wherever you put fittings... fuel leaks are no small matter, after all. A wise old one once had in his forum signature, "Having a little fuel leak is like being a little pregnant. Sooner or later it will end in tears."

 

Fittings are a restriction too, especially the 45's and 90's. But if installed correctly, should be trouble free (knocks on wood).
