Aeromotive A1000 Stealth Fuel System Issues

[CamaroSS45]

Could you guys that battled thru this advise on the "correct wiring" per Aeromoitive that worked out for you. We are in an install now and would like to avoid the trouble if we can - and it's occuring during the Holidays. It would be "very much" appreciated on the wiring routes / connections that covered you.

Much thanks! Plz....

Aeromotive directions to wire the FPCM were wrong and when my mechanic contacted them to find the correct way, it took several days and being told several different wrong ways to wire it before the correct information was given. Then we were given the run around on which MSD tach adapter that was needed to find a signal for the FPCM. MSD would say to contact Aeromotive and vice versa.

Currently everything is working fine with the addition of the FPCM and MSD tach box. I was not advised on installing a cooler on the returne side but will do so. The fuel pump appears to be nicely made, but the trouble and all of the additional parts needed to install makes it a head ache. If this new unit doesn't hold up, I'll move onto the Squash setup.

It also sucks when you have to pay labor to remove and install a new pump because it was damaged from the manufacturer.

I'll see if my mechanic is available over the holiday and ask him how he wired the A1000, fuel pump controller and MSD tach box, then post what I find out. I'll also take photos if possible.

Surely the wiring cant be that difficult ? It's only a fuel pump

My knowledge of these systems is very limited so I dont know if this is releveant, but its interesting.

All of this is needless to say - inspiring, encouraging, and ..... freakin scary!!! I am curious for more good news if any exists - or insight from Aeromotive.

I know they are using different pumps and technology but are the pump for the COPO so it begs curiosity why the trouble here.? ... ?

[stevieturbo]

It is indeed ! more info needed on that one.

You have to wonder why so many people are having problems with Aeromotive. I was going to buy the complete fuel system from them but now I don't think I will. I called them to talk about creating a fuel system that would meet the requirements for an LS9. They suggested I transplant a complete ZR1 fuel system into my car. Are you kidding me!!! I won't be giving them any of my business now, or in the future...

Made a single dyno pass last night on my combo, at 6100RPM's it went to ~20psi and crapped the bed. Screwed the regulator all the way down just to see, now the pump even with regulator all the way in makes maybe 40psi tops at idle. I have mine completely isolated with a single relay, running 10ga wire. I've installed probably 200+ of their series pumps in numerous applications (All externals).

Maybe I have a problem with the internal line, right now do not know what went wrong, frankly don't care I'll never use another Aeromotive series internal pump again.

Made 737rwhp through the unlocked 4l60E at 16psi @ 6100rpms.. Would have cracked 800+ on the low boost if I could have made a pass to 72.

Matt -

Thanks for the post here .... and you know I am in the midst of a pretty large build as well. We are just working thru the tune and shortly to WOT Dyno runs. You, like many here, know their $hit so don't believe this to be a farce - and plan to ping Aeromotive tomorrow ..... But you know the players - industry - people..... What did they tell you and what route are you taking?

I am praying there was a bad batch of these but boy we have a small group with a common theme going here and if I had to time my purchase - it was likely at the same time yours was.

Appreciate the insight and some enlightenment would be nice from the manufacturer...... Again - they make a good product as we know and if this is a flop - shocked they are not addressing or jumping in here.

Like your install - we'd double covered all bases and don't even have an issue "yet" but much like a NW102 throttle body thread I am watching - I like to know where the storm may be before it hits.

Anyone with enlightenment - jump in - share and also add ...

Thx

Hey bud,

This is actually Matt, formerly of RX ... Mine worked fine for about 40 street miles and 10'ish or so track passes. Then the fuel pressure dropped on me at idle to nearly 20psi, I knew there was a problem at that point. I cranked up the regulator just to get it moved around the shop and then onto the dyno, at 737rwhp at 6100rpm's it came down to 20psi and we shut her down. I drove the car back from the shop to home, pump was terribly loud (Overheating is my bet) and killed on me at the CVS. It did restart a few hours later and is running now..

I got with Andy @ Squash and he sent over his double pumper return style system. We are going to swap the Aeromotive soon for the Squash and I'll be back out.

At this point I cannot tell you what failed, I do not care really what failed because I cannot take the chance of a failure on my combination (Or any motor), so I've decided to ditch it. I'll let you know if we see anything when we pull it apart, could be that short EFI fuel line ate through in the tank who knows. I just know with the Squash I'll be all se to go!

I owned a full fabrication shop up north for a bunch of years, all we used for external pumps were Aeromotive or Weldon. I can say I have had VERY minimal Aeromotive failures in the past, but that is on their external pumps. I guess the internal pumps just need to be addressed. So you know I purchased mine last year about this time, but the car never ran until this October with the new pump. So if there is a common bad batch maybe it is fixed?

After the money I lost, I'll never go back to Aeromotive... Fortunately my car was idling when the fuel pressure dropped to 2 lbs and the car died...

I now have the Lingenfelter duals in the tank feeding a sump tank or cell, with an external Weldon for the rails... No worries anymore...

[Matt @ FSP]

Mine is pulled out now.. The internal hose ruptured, fixed already but it's going up for sale...

Real happy with the Squash!

Guys -

I am still running the Stealth and perhaps its new / refreshed / or my luck has not run out yet - but working solid "so far for me" and we are doing 894 rwhp / 899 ft-lb and several passes.... However - when I see a thread like this - I never forget it and assume my time will come..... There is far too much braintrust here to think you will just get lucky

For now my question is this, and really hope someone can help me - Matt is working this as well. But the way Aeromotive has their system run - and also Squash and others "I believe" if hot for the most part and surrenders the safety controls existent in the FPCM in the event of failure, and fuel will continue to gush.

Could someone please point me to the proper pinout to use the hot or ground and leverage this in our setup to maintain safety? I have searched like crazy but the way the Aeromotive is connected so it behaves just like the factory pump from an on / off / safety standpoint.

Many thanks to all
