return ful setup.

hear is a basic list of parts from summit.. this is pretty much everything you will need to make a return fuel settup.. i believe the price all together is right at 225.

1XSummit SUM-220647 - Summit® AN to NPT Adapter Fittings(goes to fuel rail)

1XSummit SUM-220687 - Summit Racing® Hose Ends(goes to fitting on the fuel rail)

1XSummit SUM-230615 - Summit® Stainless Steel Hose(you'll need to cut and assemble the line and fittings)

1XAeromotive 13101 - Aeromotive A1000 Injected Bypass Fuel Pressure RegulatorsRegulator

1XAeromotive 15609 - Aeromotive AN O-Ring Boss Adapter Fittings(input to FPR)

1XAeromotive 15617 - Aeromotive Plugs(cap off other input end of FPR)

1XAeromotive 15606 - Aeromotive AN O-Ring Boss Adapter Fittings(output of FPR)

1XEarl's Performance 983306ERL - Earl's Performance Bulkhead Adapter Fittings(goes to fuel pump assembly)

1XSummit SUM-220639 - Summit® Bulkhead Nuts

1XSummit SUM-220701 - Summit® Twist-Tite Hose Ends(goes to end of bulk end fitting that will be in the fuel tank)

1XGoodyear Replacement Belts and Hoses 65124 - Goodyear Hysunite Fuel Line/Emission Control Hose

Summit SUM-220690 - Summit Racing® Hose Ends

you could also go with a fpr that is an6 to reduce a few parts.. BUT REAMEMBER IT HAS TO BE A 1:1 REGULATOR THAT CAN HANDLE 70PSI OF FUEL PRESSURE.

hear is a 1:1 rising regulator that is capable of the 70lbs...
Aeromotive 13109 - Aeromotive A1000-6 Injected Bypass Regulators

hope this helps people with their return fuel setup.

Why is this better than the stock setup?

It allows you to run higher pressure on the fuel injectors so they flow more. A couple of companies have made 300whp on the stock injectors using a return line setup and higher pressure.

Return fuel setup & larger injectors FTW.

The only issue with running a typical setup like this is the saddle tank design that the OEM fuel tank uses. The stock fuel pump basket uses a siphon line that draws the fuel out of the other side of the tank and without it you'd run out of fuel around a 1/4 tank. I'm working on a solution for this issue with some help as we speak.

This is not the 1st time this design has been used, so do you think maybe someone else has modded a tank like this on another platform for a return fuel setup that my not have come with it originally?

Tuning can't increase pressure on the returnless?

Safety is the key on a return-less you can only go so high with fuel pressure before something gives out and I think 60 psi is the safe limit on most injectors.

I'm sure this has been run into before and an upgraded fuel pump that incorporates the saddle tank can probably be found. Or you can run separate tanks and have one with race fuel and one with normal fuel. Or you can just put another pump in the other tank and run a separate line but extra measures would have to be taken to make sure the tanks drain evenly.
