What high flow fuel pump options are there for evo's wanting to run in-tank pumps, wired up to the oem connector?

I ask, because i will be running E-85 / FP Red soon & want to know what other people are doing to satisfy their hungry evo's?

Any issues with your current high flow set-up your running?

The only decent options i am aware of are:

buschur double pumper

full blown

are there other fuel pumps available that fit the evo directly that out flow the walbro 255lph?

bosch fuel pumps?

What are people running for fuel pressure regulators as well?

Thanks for your insight

I think BR can also modify one walbro and make it flow more.. but the best option is BR double pumpers for the price and quality..

Aby, I would strongly consider a twin, parallel Walbro setup. Either the BR or Full Blown setups will do the job. I opted for the Full Blown because I wanted the clean aluminum dual housing assy. I also have dual pumps running full time, delivering proper pressure without necessitating the wiring/installation of a Hobbs switch. This is very easy to do, and I've described how to make it work in another discussion. I recommend using an adjustable FPR if you go this route.

Thanks ted. who's fpr did you go with & why?

after getting the fueling situated, i will be also in-need of improving my ignition system.

I am considering making a 300m coil set-up with a 1g ignitor....however i have a surplus of carrera gt coils with virtually no miles on them calling my name.....

Aby, I prefer Aeromotive FPRs. I've never had an issue with one, and I cannot say the same about some other brands. Additionally, they are alcohol compatible.

Full-Blown Twin Pump Setup FTW!

I run a Fuel Lab FPR, never any issues.

I would personally love to see someone come up with a Bosch 044 drop in setup for the evo. I have used tons of different pumps and definately Bosch makes some of the most reliable pumps out there (next to SX Fuel Systems).

Looks like alot of us are starting this exact discussion . I believe there is 1 ecuflash thread regarding the same thing, and 1 other thread I have stumbled on in the last week after 3 private email conversations about the same topic .

I hope to be in your position next spring!

A lot of us are getting closer to running an Evo Red with E85

Sard makes an Evo specific drop in 265l/h. They also make a universal 280l/h.

Interested as well, I'll be in the same boat very soon.

I think Mellon used the Kenne Bell Boost-a-pump for a little while on his car.

Some links for reference in the thread:

SARD fuel pumps/part numbers (look to be ~$250 market value:

Full Boost Evo twin pumper kit $399(note needs fitting kit $35 , anodized $20, shipping $10 - does not include pumps!) - $464 total + pump cost

BR kit $500 uses stock lines which should be good up to 900hp by their claims. Looks like you have to send in a core for conversion or pay the $150 core charge but the unit comes with pumps)

Both twin pumpers recommend a hobbs switch to switch the second pump on. On AEM with a trigger that would be great but I hate tuning with a hobbs when you aren't doing PSI based tuning.

And buschur reported good things tuning e85 on 1000s and much lower IDCs going from a single to double pumper. If you didn't catch it, 4x1000cc injectors run 240lph which should not max the walboro, but after pressure increases due to the FPR and static pressure that 255lph number starts dropping fast.

The issue with the dual pump setup is that the sheer capacity of the twin pumps tends to overrrun the fuel return eductor orifice, which uses the Bernoulli effect to draw fuel from the secondary part of the tank into the main section (ie. the one with the fuel pickup).

With nothing to address this, FP is excessive at idle, which creates tuning issues. You do not want this.

The conventional solution is to wire and plumb a Hobbs switch. This works just fine, but is an added headache and is something else to potentially go wrong.

I elected to make a quick, simple modification to the eductor that so far, has worked perfectly. It is described here:

To tweak everything, I recommend the use of an adjustable FPR and FP gauge, which of course necessitates an aftermarket rail. If you've done everything correctly, you should be able to set the FP very close to the factory specs at idle.

Finally, I highly advise against using anything but a liquid-filled, shock proof FP gauge. I've had more than one Autometer type eventually vibrate to pieces. The Marshall Instruments gauges are all I use now, and I highly recommend the 0-100psi liquid-filled "Shock Proof" unit either in chrome or black:

Be sure to open the drop-down menu and get the "SHOCK PROOF" series.
