Aeromotive 11540 340 Series Stealth Intank Fuel Pump, High Horsepower, 12V Electric, EFI and Carbureted Engines, Gas or E85 Fuel Type, Center Inlet

Bought this because I wanted a reliable fuel pump. The flow is overkill for my application, but I trust it because it's made in USA. Would have bought a Walbro, but they are so counterfeited not it's hard to trust them! This pump is nice and quiet compared to the OEM pump that it replaced. Pay a little extra for this so you don't have to do the job twice. This model works on most 90's Fords among many other vehicles

Installed in my 1971 Impala with upgraded LS6 ~500hp. So far it's VERY quiet compared to the Holley Fuel Pump that was provided in their kit. I'll be installing 60lb injectors and will update my review if this pump can handle it or not. Only grievance is the hydromat thats provided. The pump is nearly hitting the bottom of the tank. Since the hydromat is very thin and short, if I'm about a quarter full and the gas swashes to the back or too far to the sides, the mat holds no reserve fuel and the pump will shut off due to lack of fuel pressure. Just have to make sure to keep fuel above 1/4. Other than that, pump works great and is very quiet.

I purchased January 15 2025, failed April 10 2025. However, Aeromotive was great and sent me another one out the same day. Thank you Mr. Andrew.

The pump is silent at first when you install it. Im used to hearing pump prime when you go to start car. Made me hesitant at first because I was able to hear it prime anymore. (Its been about a month of usage and I can finally hear it priming but I have to really really listen for it.) So far its holding up the psi. Once I go boosted shortly it will know for sure if it will supply the 70 psi I need.

Installed this pump on a ls swap project super easy install pump works very good and is super quiet. Definitely better than any of the cheap off brand pumps.

I chased lean conditions with multiple Chinese knockoff in tank and in line fuel pumps before I finally spent the money and bought this one. Works great for my ls swap.

Product came in a zip lock bag with only two of the parts. Missing hose, hose clamps, connector and sleeve. Box was covered in greasie finger prints. Not sure if I received someone’s return or is this how Aeromotive does business now.

Install was fairly simple. The wires are thick and connectors are solid. I installed this in my Isuzu Rodeo. I chose the center hole because my pump had two inlets. There wasn't a 340lph pump that was a direct fit. I had to cut out a hole for the pickup and Dremel out the top of where the pump sits. I notched the top as well to clear the top port. The fuel line that was included was too short so I picked up a new piece of fuel injection line. The pump itself is slightly larger than the stock pump. You won't be able to use the OEM pump sleeve. The Aeromotive sleeve isn't rubber, its a sort of foam. It does fit right in place in the pump housing though. You will want to install the sleeve into the housing first, then install the pump. Otherwise the sleeve will bind. The pump is quiet and there is no real indication that it is anything other than stock. Currently the Rodeo is only on a single nitrous wet kit. The stock pump was having a hard time keeping up with fuel for both the injectors and nitrous feed fuel. It will be used with boost and I will update this after I am able to make sure it can hold that load.
