Aeromotive fuel system issues
Still having issues with the Aeromotive eliminator system after it being installed over a year. I've been on the phone with Aeromotive for hours, and even paid them an unannounced visit all the way in Kansas. They do not have any idea what is going on, and the marketing director even said he would but a Squash system on my car over an Aeromotive system. They recommended that I just put in a fuel cell to fix the problem....These are the issues I'm seeing:
Running full system with speed controller hooked up to a vacuum switch rather than the tach adapter. The car will shut it self off at idle (because the controller goes into fault mode) We checked the voltage to the controller and it is constantly above 14V even at idle. If we turn the key to aux and let the pump run without the car on, it never shuts off, only happens when the car is turned on. We cut out the vacuum switch and hooked it up, and it runs fine, except the pump is running at a 100% duty cycle. We are thinking the vacuum switch might be bad, but i had replaced the vacuum switch, the pump itself, the controller, replaced ALL of the wiring and checked voltage on multiple places on the car. I asked Aeromotive about the vacuum switch and if it is big enough to be able to read the vacuum. This is the part number they gave me: Digikey Corp 480-2060-ND Operating Pressure 0.04 ~ 0.79 PSI, 1.1 ~ 22" H20 Port Size Male, 1/8" (3.175mm) 27 NPT Output SPST-NC Voltage - Supply 120VAC I think that the operating presure might not be enough for the amount of pressure that I have. I'm running a 418ci ls3 with twin turbo gt35Rs and am at 10lbs of boost Any ideas or suggestions would help. I really do not want to pull out my currect system.....

Sorry to hear your problems. I have a brand new eliminator pump and 2 brand new speed controllers in my attic. We had issues after my HKE 427 install and thought it was the Aeromotive stuff. So i ordered the Squash setup. Turns out the issue was not the fuel system but the parameters in the tune dealing with throttle pedal to throttle body/blade settings. So it wasnt the Aeromotive stuff.
Oh well, still glad as hell i have the Squash in my car. Been flawless and is WAY quieter

My recommendation would be to cut your losses. I did. Went with the squash system and haven't looked back. Nobody at Aeromotive could give me a solution to the issues I was having.

Squash ftw. Call Andy and tell him to hook you up with one of his twin pump units.
You can still use your existing lines regulator etc. Just replace their pumps with his.

I heart Squash. Well worth going to it. I have had it in my car since Aug 2012 with ZERO issues.

I've been thinking Squash, but am hesitant just because of all the money ive dumped into troubleshooting the system. For the Squash system, it looks like $800 and I would reuse my Aeromotive Eliminator pump? Does it not have a controller at all? It looks like it only uses a pressure switch?

The Squash setup is twin pumps 400lph or 450lph (e85 version) in stock fuel bucket. There is no controller. I am running a return style system that uses a regulator and Hobbs switches. Andy is getting ready to debut a returnless system called the Uber Fueler that does everything the current setup does minus the return lines and regulator and is good over 1000hp+.
You would take out the eliminator setup, get rid of the controller, put in the Squash, tune out the FPCM, wire it up and go. |

Wish I would have posted this a week earlier! I was just in KCMO last week! Also stopped by IPS since they've worked with Aeromotive quite a bit.

You would replace the Eliminator pump with the Squash twin in-tank pumps. You should already have the FPCM disabled with your current system. ou can keep the existing AN lines and regulator.
You can sell you pump to make some $$$ back. I Andy's stuff on a couple of trucks and they have been great. I just received another one from him yesterday that I am putting on the Silverado cause I was running out of fuel with the spray.

What, exactly, do you want pics of? Upper left corner is the regulator. The Hobbs switch is in the upper right corner. If you can follow the line going over the brake reservoir and see the blue fitting, the Hobbs switch is the silver piece next to it. It comes out the opposite side of my vacuum log. If this isn't what you wanted pics of, let me know.
