Hi Dwight,
I'm using Aeromotive 18688 Phantom 340 Fuel Pump System. Just got it few days ago. Didn't install it yet, still need to build my fuel tanks. The build quality looks great and it comes with it's own "sump".
My engine is a 5.0 Coyote. Called Aeromotive and they recommended this system for my engine. All it needs externally is a fuel filter, regulator and piping.
Regards,
Renato

Paul, are you running the Aeromotive pump in the long narrow tanks of a '40 or in a Cobra tank (another post of yours mentioned Cobra)? There could be a big distinction between the two.
I’m assuming you have efi eight stack, what horsepower are you rated? <?xml:namespace prefix = "o" ns = "urn:schemas-microsoft-com<img src=" /><o

<o></o>
You’ve never ever had gas starvation on a low (1/4) tank under hard braking? <o></o>
<o></o>
Also just to clarify, Aeromotive offers the Stealth pump by itself or you can buy the kit with the sump called “Phantom Stealth”. You simply said Stealth, did you mean the Phantom Stealth?
<o></o>
I called the tech support at Aeromotive today and frankly the tech didn’t even try to impress me with the Phatom Stealth’s capability. He had no specification as to how much the sump held and for how long it would hold fuel if the area around it went dry. He said some other things that weren’t too encouraging as well which left me with more questions than I started with. I figured he just had a long weekend and really wasn’t in the mood to answer questions he’s already been asked a million times.

I am running the Phantom Stealth system in a Cobra tank. Currently running a set of 48IDA's on an FE - 500+hp. I am in the process of converting to an EightStack system, planning the full conversion this winter.
My fuel tank is baffled and the Phantom System is installed inside those baffles so I've never experienced any starvation. But with carbs, it isn't a complete test since they have the benefit of the fuel bowl capacity.
I really don't think fuel starvation will be an issue. The system will hold about 1/2 gallon of fuel inside the bladder/foam cell. There are inlet holes in the bottom and I don't think they will allow the fuel to spill out fast enough, even with an empty tank, that the pump will run dry.
Don't know how well he explained the system to you. The fuel pump is located inside a rubber bladder that is lined with foam. I am guessing the capacity to be around 1/2 gallon. The overflow from the system empties out back into this same bladder so it is always "over-full" compared to the rest of the tank. There are a couple small holes in the bottom of the bladder that allows the fuel to be taken into the system.
I'd call back and talk to another tech. I've found Aeromotive to always be very helpful. You might have got one on a bad day. Explain your concerns to them and I feel confident they'll have the answers for you.

Thanks Paul, I appreciate the explanation, it helps a lot. The tech would not elaborate on the bypass fuel coming into the bladder and to what extent it helps maintain fuel capacity in the bladder vs the escaping fuel out the bottom holes along with the pump demand. That's my concern, you helped explain that.
What kind of regulator are you using to get the pressure down to the 3-4lbs Webers like? Also, where is your fuel bypass, off the regulator?
The'40 tanks, when low, are notorious for fuel surging forward and away from the fuel pickup at the rear (long narrow tanks). With efi demands, a sump of sorts is mandatory and not many options of where to place one. One of our esteemed members on this forum sent me a link to another product that would surely work, thanks Scott. It's also an internal sump and pump design but they do get pricey.

I am using an Aeromotive regulator (13301). My fuel line runs to a Y at the front of the block and each branch then goes to the fuel lines/log on each bank. At the end, I run flex lines from carb back to the regulator. That regulator then dumps back to the tank to complete the return system.
The regulator comes with two springs, one for EFI and one for Carbs, and it would go down to about 3psi. I MacGiver'd another spring to make the system work as low as 2-1/2 psi. I then set it for 3-1/2 and all has been well. I know many suggest the Holley regulator but my experience with them is they are pretty cheap and very un-reliable.
The only drawback to the Aeromotive stuff is it can get pretty pricey. But you get what you pay for. The Holley regulator was only $20 but the Aeromotive unit is $140 :stunned: The Aeromotive sump systems are going to set you back $500 or more :shocked:
Aeromotive originally came out with a sump system to combat the surge problems associated with high-G launches for drag racing. They quickly learned it also solved a bunch of problems for the Road Race community. But the original design was labor intensive - you had to cut and weld the tank. The Phantom Stealth product solved this problem and also opened up the market to the Resto-Mod guys where they are trying to put EFI systems into cars with no-sump tanks.
I don't know how much clearance you have above the long tanks. My tank is within 7/8" of the trunk floor and that is enough room for the outlets on the Phantom unit.
