-8an feed and return?
-8an feed and return? Re-doing my fuel system after I noticed a leak from an aluminum line that was initially used when I got my fuel system(it was free). Running 1 of the 2 340lph pumps that are in the tank now and 1/2in alum hardline feed(to the y-block) and 3/8 hardline return. Down the road plan is to go turbo, I know this is overkill for my current setup. Is there any issue with -8an feed AND return?
My current plan/idea is to run Earls SS hardlines (1/2in) utilizing 37* single flares and tube nuts from the fuel filter to the y-block at the rails and from the regulator to the tank. I have a 1/2in rigid bender and really don't want to have to purchase a separate 3/8 bender to do the job unless necessary. I have a mastercool hydro flare kit to take care of the 37* flares on the stainless tube.
Id like to stick with the hardline, so really not considering AN hose for the main chassis lines at this time.
Thoughts/advice would be appreciated before I pull the trigger on the lines and fittings I will need.

I have no stock lines in the car, as I stated the car has a full fuel system but the lines I got are aluminum but the aluminum fuel line started to leak at the y-block fitting where it transitions from the hardline to AN. I would only be out the cost of the hardline, tube nuts, and a few misc fittings. I got the entire fuel system for free (twin pumps, 99+ tank, rails, lines, fuel filter, all associated fittings).

I don't know why you say it isn't common. An 8/8 setup is probably the most commonly used on this forum for boost.

I went 8/8 so i could buy one roll of line and one size of fittings. Since it was my first one i wasnt sure how much of all of it i needed so this kept me from being over on one size and not enough on another. Also if anything ever needs to be replaced, no question about which one I would need to buy or keep in stock. Made sense to me.

+1,, any pressure on the relief of a regulator can lead to intermittent fueling problems that will put you in a padded cell trying to tune them out.. Burnt out two really expensive pumps a few years back that way..

Just did a 8/6 setup with dual 450s, I could get pressure down to about 35 before the return could not flow anymore back to the tank. Just a tidbit of info.
What size is the OEM line? I was just guessing its enough to feed a motor its big enough to spit it back?

No, I used PTFE line for e85. Mine was done in stainless mesh, and the last one I did was the black nylon mesh.
