I really like the self learning efi systems. I will do one again when money allows. The last one I did, I had it plumbed like a carb. The return line was off the universal regulator down on the frame rail, and I dead headed it up to the Throttle body....Aeromotive A1000 pump and their universal regulator.
This allowed my to swap the spring in the regulator and go right back to a carb in less than an hour. All my brackets and such fit the throttle body and the carb.....It came in real handy one time the efi quit and I had to send it back to have it fixed.
So I would go efi, and carry the spring for the regulator and the carb with me as back up.
Dragula do you see a need or benefit to running the aeromotive pump speed controller with this setup?
I have the A1000 pump and the Holley Super Sniper EFI stealth 4150 system in hand and the aeromotive A1000 regulator will be here on Friday.
I presume I just plumb this setup like its a carb?
I would call Aeromotive. The A1000 only draws 8 amps. If you fuel system does not have a lot of 90's or crazy stuff in it, you probably wouldn't really benefit from it, but I would call them and get their take on it. Anything that induces turbulence like steps in the hose sizes or hard 90, increases the fuel temp over time. Fuel gets like bath water warm in a short period of time....So just keep it simple is my motto...
Now I just did this on my 605 Hemi as well....It had a 1250 Dominator on it, swapped springs in the regulator and slapped a Holley Sniper Stealth 4500 on it. Works great....That is twice now I have done it this way. I also added a Holley Pro Dash and can bused it into the efi so I get all the readings on it plus GPS speedometer.
So to be clear, my regulator returns excess fuel, but from the regulator, I only feed the carb or TBI with one AN08 dead head line. I do not return the fuel in that short run up to the TBI
