I am currently away from my vehicle and was wondering if a 2005 2500 Suburban with the 6.0l non flex fuel has two fuel lines that come up to the fuel rails (input and return), or just one with fuel pressure regulator in tank?

It should just be returnless

Nice build! Built suburbans are so badass...

I have seen that sump thing before, but havent seen anyone use it. I just dont like the idea of cutting up the stock tank with a nice catch sitting under there waiting to get knocked off.

If you plan to run e85 you want at least 20psi with that low of a compression engine...whats your power goal?

Those 80s wont go as far as you think on e85.

If I can hit that 800hp mark I would be happy. I plan on doing two different tunes one for the e85 and another for 93. I want the ability to run e85 but may find out 93 with meth may be used more.

80s are way, way too small for e85.

Even with huge fuel pumps you could maybe get 650rwhp out of 80s on e85.

With dual walbro 450s, you would need 96lb@4bar injectors to just barely get you there, assuming you only run 20psi of boost.

Ok, well they just arrived in the mail so time to swap them out for bigger. Thanks for the input!

I did order a Magnafuel 4303 and Aeromotive 13129 - EFI Bypass Regulator along with the pre and post filters today!

This shall do a nice job at moving some fuel around!
