Fuel System for Eaton Swap

[8UWITH6]

Im a little confused on which route to take on this. Some say get a 40 amp boost a pump and others say replace the pump in the tank.

My swap will be an "under 400hp" swap so I am not looking to really crank it up a bunch and push the limits of the stock block/internals. However, I dont want to put a band-aid on the fuel system to make it work.

With that said I have no problem replacing the in tank pump. But is that ALL I would need to do? Would the tune take care of the rest? Which pump? I have heard Focus SVT, etc. What about Walboro? I have used them for years with good luck in my Buick's. Basically I am needing part numbers or suggestions. I have access to several aftermarket parts suppliers through work and get decent pricing. Any information you fellas can provide would be helpful. Thanks!

Put this in the tank and you are good for 450RWHP without a BAP.

I have a Aeromotive Stealth 340..it was recommended to me by MO's when they did my centri install..mine came with a 255 Walbro. I also have a BAP, just 20 amp as I intend to go no further, other than an intercooler some day. A 40 amp really isn't required unles you plan on higher Hp later..although they are only like $30.00 more..but I found a 20 amp for a very good price.

[SC Cheesehead]

I'm running a GT fuel pump with a BAP.

BAP's are a joke! Exactly what you said a band aid. Get a Walboro 410lph pump & be done. They are fairly cheap & will supply more fuel then a Eaton swap needs. Make sure you do the fuel filter mod also.

[jwibbity]

have to ask marty but im making 428 with no boost a pump, think its a gt40 pump

Yup, the Walbro 400's are awesome. They put the Stealths to shame in flow, voltage draw, price, and reliability. Which is good for the FPDM to prevent over heating and your wiring from cooking.

[8UWITH6]

Bodyman. I saw the fuel filter mod and was going to ask if that's necessary.

[MOTOWN]

Im running dual Walbro 400lph pumps in a return style setup, the walbro 400 will not work properly in a retunless setup, went over this several times with Walbro techs the pressure will be too high, and it will constantly throw codes.

Your best bet is the Aeromotive pump, and i totally agree boost a pumps are a joke! just upgrade your pump, heavier gauge wire, and a modified FPDM, the fuel filter mod is a must!

[8UWITH6]

Okay so isnt that Aeromotive 340 the same as a Walboro 340? I have been running Walboro's in my Buicks for 13 years with little to no problems.............. can I just get one of those?

What is a FPDM? The driver module?

And upgrading wiring. What is sufficient? We always run 10 gauge from the alternator back to the tank on the Buicks. Is that good enough for this setup? I dont see why not.

Sorry for all the Buick references, its what I know ;) :beer: But Im learning.

The 340 may work, the 400 was not designed for a returnless system, The Aeromotive 340 is a plug and play, i know the Walbro 400 uses a different style plug end.

Yes the FPDM is the fuel pump drive module which regulates pressure/volume for the pump, 10 gauge wire is what i have as well.

On my Buick i ran dual external paxton pumps, which are now aeromotive a1000, and -10 lines!

[8UWITH6]

Okay, I am not worried about changing plugs. I can get Walboro 340's for around 100 dollars. But if its going to take a lot to make it work 179 for the Aero aint bad.

Do I have to replace the FPDM and if so how much and where do I get it?

I figured the tune would take care of that part of it.

Again still learning.

While Im asking questions is a MAFIA necessary and what does it do? Does it just translate/change the reading to the PCM like a translator or translator plus does on the Buicks?

Thanks again.

You can get an Aeromotive pump new off ebay for 150ish shipped, or go with the Walbro 340, i would get a modified FPDM to avoid thermo shut downs.

I wouldnt bother with a mafia (another band aid device) just get a Lightning maf, or a SCT BA3000.

the mafia extends the range of the maf, i think Lethal performance sells modified FPDMs

[8UWITH6]

I have a 90mm Cobra or Lightning MAF that came with my parts purchase............ thats all I need it sounds like......

And where do I get the modified FPDM.

Thanks for all your help.

Do a search on how to. It is a restrictive area in fuel lines.

You summed it up rt there.

[BODYMAN]

For a single pump a modded FPDM is not nesc.

[8UWITH6]

Thanks guys

I followed the advice on the Eaton swap threads and bought the 90mm Lightning MAF, Diablo MAFia and the 20 amp BAP. I have a Walbro 255lph pump and a stock lower end. So your guys opinion is that I don't need the MAFia and BAP? Only a fuel filter mod by musclemerc.....??

I could definitely use the money for other stuff.

You dont need the boost a pump, you can use the mafia since you have it, just upgrade your fuel pump wiring, the fuel pump mod addresses the 90* bends in the factory fuel lines where they are almost completely kinked!:eek:

[tbone]

Why would I need to upgrade the fuel pump wiring if I've been using the Walbro 255 with no issues? I can easily return the Diablo MAFia if I don't need it.....
I thought about ordering musclemercs fuel filter mod, but wondered whether it was really necessary.

Aftermarket pumps can pull more amps than the factory wiring can handle in some applications, not sure what the amperage draw on your particular pump is right off hand, but its cheap insurance!

[1stMerc]

This site never fails to provide great info. Keep up the good work.

Todd good to see you posting again.

[8UWITH6]

On the wiring all I need to upgrade is the signal wire to the pump correct? Is there a how to on that I don't want to screw with the PCM by doing it wrong. Do I just use a relay and use the factory wire for the trigger?

If i were keeping a return style fuel setup i would run a dedicated 4 or 6 gauge wire form the FPDM directly to the battery with an inline fuse.

The wires from the FPDM to the fuel pump hat i would upgrade to 8 or 10 gauge and be good to go.

[8UWITH6]

How much current can a fuel pump need? I have built sound systems that dont need that gauge of wire! ;)

LOL. All jokes aside it sounds like I need a good fuel pump and probably make an 8 gauge wiring harness for the module and the pump and then do the fuel filter mod............ 11psi max boost, stock block, not trying to be a dyno queen. I am just trying to make some safe reliable power.


Yes? No? Thanks fellas you are all very helpful!

I don't remember anyone expressing a thermal shut down with a combo of a GT in tank & 40 amp boost a pump. I am aware of wire upgrade. How strongly is a FPDM recomended ? Have there been that many cases reported ?

Not sure, just stating how i would upgrade it.

I have access to a oem Cobra fuel pump. I also can get an OE fuel hat modded for larger gauge wire. Will this work or not? I guess I should mention I have access to a FPDM and FRPS sounds like that's not a bad idea to have laying around. Oh and as n 04 Cobra fuel rail. These are all off of my buddies car. Of these items what can I use? I am leaning towards a new pump but am curious.

Don't need the Cobra fuel rail.

An extra FRPS is always good to have.

DTR + 4.10's + Eaton swap = Wreeeeeeeeeeeeeeedom

[8UWITH6]

Rail would be nice to have if I can get it cheap so I could assemble the fuel system on the intake prior to install. What about the other parts? Is the fuel hat compatible?

Hell, you can have my Cobra fuel rail for free.

I'm pretty sure the hat is not compatible. But I'm not 100% sure on this.

The fuel hat isnt close to being compatible, i modded a DivisionX hat, totally different orientation of the pump location.

Thanks guys. Thoughts on the pump?

Aeromotive is your best option!

Loud and clear. So to finish this thread off. Aeromotive pump, 179.00, 39# Injectors (have), fuel filter mod (few bux at the parts store), upgrade wiring (few bux at the parts store), factory FPDM and FPRS (will have a spare of each just in case) and let'r'rip taterchip?!?!?! :beer:

I am the same way thats why I wanted to know about the factory Cobra pump. Makes sense either way new vs used in this case. Thanks again everyone.

I just may buy one of these and just unplug my BAP. Or just leave the BAP alone and if it fails. No foks given.

All this talk about upgrading the wiring.. I ran a 255 for over three YEARS and a 340 since April with at least 45,000 total mileage between the two in hot as **** weather and never once had an issue!

Straight from Walbro at SEMA "The 400's work fine with a pulse width Ford returnless system" Save yourself $50-$60 and a tow bill. I've personally seen 5 Stealths fail now.

I have two Walbro 400s now in a return setup, i tried one in the returnless setup, and so have other members, they do not work without throwing codes like crazy and giving the fprs fits!

Been there done that! the pump pushes way too much fuel for a returnless system.:shake:

Then the tuner did not adjust the Pump Voltage tables correctly. They work great if you (PRP) or your tuner know what you're doing with the calibration.
