Stock fuel lines and E85
Ok, so I am running out of fuel at around 600 whp on race fuel due to the Walbro pump. I have decided to add a second fuel pump intank next to the original and have it come on at 10 psi with the AEM. What I'm trying to figure out is if the stock fuel lines will be large enough to handle running E85 since more fuel will be needed to stay at around 600 whp? Are the stock fuel lines ok to use with E85? How much whp can I possibly make on the stock fuel lines and E85? I'm trying my best to do the second Walbro pump upgrade and not have to mess with the fuel line at all if I can. If they will flow enough for around 650-700 whp on E85 I'll be set. Anyone have any knowledge on the stock fuel lines?
Thanks
Thanks

I don't think you'll be able to run that kind of power on stock fuel lines and E85. Plus the stock fuel lines are push lock back by the tank, so unless you somehow foresee using the stock fuel pump hanger, with 2 pumps, which isn't possible to do in a clean, safe manner, you are going to need to replace them anyways.
E85 is much more demanding on a fuel system than race gas. For obvious reasons.

I dont think its the size of the line, its the material of the line. (NOT 100%) but the lines need to be made of a different material, (due to the GRAIN ALCOHOL CONTENT). The material needs to be changed i believe as the stock rubber material lines will eventually deteriorate. (Not 100%)
Just mount an aftermarket puller pump inline with the stock Walbro outside the tank (mount it under the spare tire area and then run larger line to the front.
E85 in my opinion, is pointless unless you live somewhere (like Nebraska) where you can get it at every gas station. Here is AZ there are like 5-7 gas stations in the whole STATE. So if you tune on it and actually drive your car (your using twice amount of full with E85) you will eventually not be able to get gas at your convenience. I say stick with race fuel C16 or whatever you like and just upgrade the system, dont do E85. My .02

Im making 620whp on stock fuel lines and E85 no problem. Im using the Bosch 044 inline pump which is a great alternative to duel pumps fed by a intank walbro and have had no problems. Just make sure you have a fuel pressure reg.

instead of duals in the tank and relying on the stock lines to support all the fuel, do a single intank and a bosch inline then from the bosch inline use SS braided line to the fuel rail. tony1 has all the stuff you need to setup the bosch inline, including the pump and mounting kit with a relay included.

I've read mix reviews on this as I was interested in the same idea. How are you adding the second pump in? I'd love to do that!
