in tank fuel lines for e85 Looking to build a intank twin pump system. Since I will be using e85 I cant use rubber fuel lines. I am running teflon braided hoses to motor. My question is what lines do in use directly from the pumps to the hat and what Y fitting? Thanks...
The go to is the OEM style corrugated flex hose that you get with most pumps. I run one from each pump into a Y that goes up to the fuel hat on my aluminum hanger. Twin 450's with a -8 feed an -6 return. All PTFE hoses and fittings.

What Y did you use? Where did you get the corrugated flex hose from. Thanks for your help.
As for the pumps, they came with the internal lines and I purchased a CNC aluminum hanger from a guy on FB who makes them. It came with the Y and fittings all ready to drop in. Very nice setup.
Chris Ebeling is his name and you should be able to find him by name or by searching keywords. Great guy and if you send him your stock bucket he will cut off the level sensor and install it on the hanger.

I have a 98 Camaro with the steel tank with the baffle. As a result of the baffle the filters on my Racetronic dual fuel pump kit on the swing arm draw fuel from the rear of the tank on the backward side of the baffle.
I had to seriously modify the swing arm when mounting the dual pumps on the swing arm. I describe it as a swing arm because it is spring loaded and hangs at an angle pointing toward the rear of the tank. It's a bxxxxh to install into the tank with dual pumps because the filters want to hang up on the metal baffle inside the tank.
Anybody know if you can simply hang the pumps directly straight down into the tank and avoid fuel starvation/cavitation when low on fuel in a 98 steel tank?.
It appears this kit eliminates the 99-2000 fuel capsule/bucket to hold fuel to avoid fuel starvation when low on fuel. Return fuel runs into the capsule and a venturi tube pulls fuel into the capsule to feed the pumps avoiding fuel starvation/cavitation.
So with this kit, since there is no fuel capsule, what is the minimum fuel level you run and not have fuel starvation/cavitation?
Another downside with the 98 fuel tank assembly is the small bulkhead connector that only supports 14 amps. It looks as if this CNC hat/hanger kit uses the newer upgraded 150/280 28 amp bulkhead connector.
TO OP
Racetronix sells convoluted in tank fuel hose in various lengths for gas,race gas, e85. Think largest ID is -6an.
