Hi guys

Have any of you used the huge 1000hp aeromotive pump setup before? If so how did you run the 10an line to the tank? Did you just put it in through the top?

I am thinking about the following:

Aeromotive 1000hp pump, regulator, and filter
10an line up to Y-block then into billet rails
Yblock off other end of rails into stock line for return

Questions:

Did you just remove the stock intank pump leaving everything else inside and run the 10an line from the top of the tank to the bottom?

Did your fuel gauge still work? If not how did you get it to work

How did you wire up the aeromotive? Tie into the stock relay? Used your own relay? Just hotwired to the battery and started off of a switch in the cockpit?

How noisy is the pump and did you use rubber mounts, or isolators for it?

Thanks again!
Chris

i know those y blocks are expensive, that was a deciding factor against them for me... -10 is expesive too, whats your hp goals now?? one -10 will support well over 1000hp

CHRISPY

Goals are to do it once and forget it

Realistically 600RWHP is the target for now potential for 800RWHP down the road.

Thanks,
Chris

thats actualy the smaller one i have the pro-series its silver on my turbo trans am i have the red 1000hp pump sitting on the shelf here the pro is 12an in and out

I would do a racetronix dual intank setup (or just make your own if they don't have one) - it will be much more reliable and quieter than the aeromotive option.

agree with above but some people just like those externals

CHRISPY

Externals are a snap to replace if there are problems.

I elected to get a Speed Inc. drag tank and run an external Weldon 2025 pump, with -10 to the front and a -6 return.

I would sump a tank and run an external fuel pump

ChrisB

Cut an access panel and internal pumps take virtually the same amount of time.

But if you want external run 2 walbro inline 255lph pumps.

I wouldn't bother with the aeromotive stuff honestly - it seems *very* hit and miss, and everyone I know who has one has had a problem at some point or another.

What do you do when the lines can't support the amount of fuel being pumped? The external pumps make it easy to use larger lines. Just a thought.

ChrisB

Run bigger lines

Not much more difficult at all with the in tank, but if you want external I would still run two inline walbro's with a pickup/sump.

I have been running a 10an pickup right through the top of the tank assembly.
Just removed the intank pump and made a custom pickup out of some 1/2" copper fittings and tubing with 10An line going into the pump.

Mounted the aeromotive pump with rubber blocks, and Injector o-rings on the nuts and bolts for no metal to metal contact of car to pump.
You CAN NOT HEAR THE PUMP while driving.
I then used a few various fittings to tie into the stock feed line.
Works fine.
fuel level sender is not affected.


I am now installing a separate 4 gallon cell in the hatch well area.
Using twin 3 way valves to switch back and forth between stock tank for street and fuel cell filled with serious race fuel for strip.
And of course a firewall will be added for the cell.
Fwiw, I had previously been using twin intank pumps but one of them failed after a while. It was not the racetronix system though. But it was a very good pump that failed. Problem with that is it's hard to tell if one pump dies.
I only found out because I had each pump wired so I could test them individually.

Thanks Steve, that sounds like exactly what I want to do. 10an line with the Aeromotive big enough? Are you just plumbing into the stock line or going 10an all the way up?

Are you running custom rails and return?

How about regulator?

How exactly did you run the line in through the top?

Is the pump operated off a switch?

thanks and sorry for all the questions hehe,
Chris

I was running modded stock rails. Will be switching to high volume rails. Pass side was running leaner than drivers.

I am going to run 8an from pump to rails. That's plenty big enough.
I have been using a aeromotive regulator and will stick with it.

I cut off the stock feed line from the tank assembly. Drilled it out and installed a 90 degree 1/2" barb fitting. Soldered that to seal it to the tank assembly.Then just installed 10an line onto that fitting to the pump which is mounted about 12" away.
This is on a 98 tank assembly.
I have the pump wired into the stock fuel pump wiring.
It will give me 60+psi with 100% duty cycle through 42.5lb injectors.
That's about 70GPH of fuel and enough for around 700-750 crank hp.

Only problem I have had is the pump heats up on hot days in stop and go driving after about 45mins to an hour.
But my return had been to small. I was only using 1/4 ID return line.

Sorry to interject....you cut the stock feed line right at the tank or a few inches after? are you using the stock line as the return? where is that going in?

CHRISPY

The return line T's off at the junction by the fuel filter and goes back to the tank. It is pretty clear when you are under the car.

RyanJ

yeah...I know, but when most guys use a secondary feed and use the stock for return they delete the Y, so I was just wondering.

my ultimate fuel system would have to be a stock tank -> -10 pickup -> filter -> big 'ol pump -> filter -> -10 feed -> Y -> 2x -6 to billet rails -> 2x -6 out intersecting into the regulator -> stock feed as a return...or -6 return to tank. -Or even sump the stock tank or get a cell with vent lintes, etc.- Now, I used -10 because of the context of the thread, but I'd choose -8 lines since they would handle the HP you need. But...bigger IS better With a big-enough pump (silver aero) it should handle your volume and then you could set your base FP a little lower and use an injector driver with 65's or 72's up front. That should be plenty of room to grow.

Here are some pics of My pickup.-> http://community.webshots.com/album/100014932PHedew

Not seen in pic3 is the 10an hose that connects the pickup to the tank sock.

Thanks Steve. Thats what I was wondering.
