My surge tank has a bosch 044 mounted in it. Pump in the tank is stock, no reason to upgrade the stock pump when it is just used to fill the surge tank. When I did the math I would have to do full throttle, in 6th gear, at 5,000+RPM's for over 6 minutes to empty my surge tank.

Changed mine up a bit, I have to finish the lines tonight then wire up the pumps. Once I have the engine on the stand I'll lay out the distribution block and regulator.

holy **** very nice man ^^! very clean work!

couple of questions for you guys. i have been hearing aeromotive fpr's arent good past 75 psi?? never had an issue yet just wondering what yalls experience is.

also my base fp is about 45 psi. boost is in the 25-35 region. 35 psi plus 45 of base idle is what 80 psi. is that an issue for fpr, as well as will that kill my in tank walbro 255's?

volume is not a problem as i have the 2 walbros feeding an elminator fuel pump and all feed lines are -12 so not issues there. just wondering if i need to get a different fpr and am i pushing the wally's to hard?

eliminator pump comes on whenever i tell it to ( 15 psi). other than that the 255's take care of everything. system works great

Depending on the Aeromotive regulator you're using, ( I use the A1000)

BASE pressure is adjustable from 40-75psi, pressure will raise on a 1:1 ratio with mani pressure.

You could adjust your BASE pressure all the way up to 75psi and the fuel pressure will still rise on a 1:1 ratio, I doubt you'll be running 110psi total fuel pressure.

You're fine with what you have most likely.

How much power are you putting down?

I think the A1000 is good up to 650 or so.

Thanks!

I would like to know the answer here as well. Aeromotive didnt see any problems with me using it for mine and I had not heard that but if thats the case it would be great to know now before I get to that part lol.

Good to hear.

Aeromotive claims 1000 but I doubt it and definitely not on E85, I would like to see 600 out of my setup and I will be happy.

I dont use the a1000. the eliminator is actually rated at much more horsepower. Power wise 500-750 ish depending on boost. been a long time project finally starting to come together.

i read someone saying the other day the walbros after like 80 psi open the relief valve thats why i asked. the system works i just wondered in case i set something up in a way i shouldnt have.

also im not using a surge tank, so when im hooked up the walbros and aero are all flowing at once . that way the eliminator doesnt run all the time only when i need it (at 15 psi or more) and the system as a total is adequate for huge huge power but it can still idle and return fuel fast enough!

This is why I use Fuelab AFPR's in my builds. Never had a problem running them all the way up to 90psi before. They are rated 0-100 and 0-150 depending on the regulator you buy.

why not just use two in tank pumps, one full time one on a hobbs switch. very easy to do and will support your goal of 600 on e85 no problem

i considered that for a while and did end up messing with that setup but then i decided i wanted to do it overkill and do it once. 2 in tanks 255's feeding the eliminator and -12 to engine bay, the y to -8 feed lines that come with the aeromotive fuel rails. maybe not the best setup for road course stuff i imagine but for street cruising and the occasional high boost pull i dont see it as being any kind of a problem. im just after big power for high way pulls and such lol.

Because the car is used for TT and an in tank pump will have starvation issues out the ass and with more than 10K in an engine its well worth the extra complexity and expense to do it right. Aditionallly there are no good double pump option available yet for the 08+ style hanger and I dont feel like fabricating one at the moment.

thank you. is it a nice piece? and my aero fpr has like 3 ports on it. would it be hard to use the fuel labs one(any fitting conversion needed) and are the inlets like -8 or -6 maybe? thx for info

wow that sucks ass man sorry didnt honestly know that. and dont gotta be snappy ^ ! well in that case, maybe single pump feeding surge and then in line pump?? could use any of the inline pumps i would imagine and be ok. just remember if you run the in line pump all the time you will need the fuel pump controller or youll kill the pump. thats why i used the switch idea.

No one is being snappy. That is exactly the setup. Single DW intank feeding the surge tank. A1000 is controlled that same way as the stock in tank pump is off the OEM controller so it mimics everyting happening in the tank.

Stock controler switches a relay, both the A1000 and In tank are wired to the battery via the relay.

Thanks, if it doesnt work Ill change it up but at least the components have room to grow on. In the end it will have a fuel cell hence the removable trunk floor and not a perminant one.

Its sealed, behind a bulkhead so not in the drivers compartment and has terminal covers thus complies with all NASA rules as far as I understand them right? I see no reason for a box if they dont I guess unless I am missing something in there in which case I would run one.

-6 or -10 side inlets, and always a -6 an return.

I just run -6an, you don't need anything bigger, unless your running 750+whp.
