Dual Fuel Pumps

[Brian Verson]

I'm needing some information on a Dual Pump intank setup. I'm looking at the ss340m Walboro pump from racetronix. They r as of no help when it comes to answering an e-mail. So I'm turning to you guy's for the answers i seek. I have the hotwire setup from caspers w/the relay. Will it supply enough puwer for both pumps or is there a different wiring setup i may need. I'm upgrading the supply and the return lines. Is a 8an feed with a 6an return line big enough or do I need to go with a 10 an / 6 what I need. What do I need to do with the fuel pump hanger to be able to get the proper amount of fuel into the line so I dont run lean . Help. Thanks

I had a dual pump setup similar to the one you're describing, including the Casper's kit with the relay. Included in the kit, was a switch mounted under the hood which triggered the second pump when you reached a certain amount of boost. When driving normally, only one pump was running, but as soon as the boost level exceeded 10lbs, then the second pump kicked in. You could adjust the switch for the second pump to come on at any boost level desired (mine was set at 10lbs...). As for upgrading the fuel lines, I now have some 10an supply and 8an return lines.
Hope this helps,

good luck!

If you want a Racetronics setup you better contact one of his vendors like Julio at Alkycontrol. Racetronics is horrible with email or even answering a question. I went with a Reds double pumper- one phone call. If you need their number send me a PM

I answered your e-mail and indicated that we did not have anything using a Walbro pump to support E85 reliably especially at the volume required to support 6 x 120lb injectors. Walbro HP pumps are not certified for use with E85. Most of a TR's fuel system is not E85-friendly. If you are determined on trying a DP system then all the parts you need to build one are available in our kit DPK-003.
A single 12 gauge CP HW harness is not enough to support two in-tank pumps nor is it configured to provide proper circuit protection. Each pump requires its own dedicated / separate fused circuit. This is the way the Racetronix DP system is designed. A -8 feed and -6 Teflon return line are more than enough to support your HP level. Synthetic rubber lines are no good for E85. You should consider a new Delphi SS fuel pump hanger for use with E85.

I do apologize for the late reply but your E85/DP question falls in my domain and due to personal reasons I have had limited time to spend answering these types of questions lately. I do not feel your statement above is justified or required on this forum.

If you require phone sales / support I recommend you contact Turbotweak, Eric's Performance Parts or Lonnie's Performance (DP specialist)

I tried that route , they were unable to get me the answers I needed because they wern't able to reach anyone at racetronix. If I have to wait a week for your company to return an e-mail on product that im looking too purchase. Then maybe you don't need my business . The post that I put up on this board wasn't meant to be mean I just wanted answers to my questions that you wern't answering .

Why stay in tank if your changing out the lines any way just get an external pump that is good for E-85 cost is going to be the same and you can get a rebuildable 2 speed pump.

"Most of a TR's fuel system is not E85-friendly"
hmm I would not agree with this statement at all.

Ethanol attacks rubber and metal parts and that is one of the reasons there is none in new car fuel systems. Vapor seepage is another.

Perhaps you can explain your reasoning which contradicts that of GM and TI engineers?

The best way to explain it is to say people have been running it for years with no issues. So will we have issues 10 15 20 years down the road not sure, but by then we will be running rocket fuel or something else :biggrin: now relax and smile
