  • Best bang for your buck.
These are probably the best fuel pumps in this price range. I've used them on 4 LS swaps in squarebody Chevrolet trucks. Yeah they're not a direct fit wahhhh, this is a universal fuel pump. It works makes great fuel pressure.

  • fits 00 Jeep XJ 4.0 (stage 3 build)
Installed on 00 Jeep XJ 4.0 4x4...modified the stock baffle & it works like a charm. Noise level is minimal. The fuel economy seems to be the same, truly hi-flow though. Noticable increase in motor power considering Ive built the L6. Overall, excellent product. Tinker till success.

  • 10 yrs in a K swap
After 10 years of constant use... Mine is finally checking out.. Worth it . Put in 2016 and now Feb.2026 I am finally experiencing fuel pressure loss. I had changed my Fuel Regulator diaphragm 3 days a go after fuel loss , but now I am experiencing pressure loss again. Like I said 2016 , I think it exceeded its life . Thank You AEM for a great product. ... show more

  • Best pump for the price
This is a great in tank pump. Not too noisy and provides consistent, strong fuel pressure. Worked great for my application, LS Swapped a 1981 GMC K10. Will report back when I turbo the truck, curious to see how the pump will perform. Would definitely buy again.

  • Been running strong for 3 years!! Fits SAAB 9-3 Aero
Bought this pump in 2017 and have been running it in my 2007 SAAB 9-3 Aero with the B284 engine for the past 3 years with no issues. Installed it myself in the driveway with hand tools. It was basically a drop in swap with the factory pump with 2 things to note: 1) You will need to get electrical tabs to connect to the the open wires on the AEM connector (or re-use the originals from the old pump if you are in a pinch which is not fun). 2) You must reuse the factory strainer filter as the supplied one doesn't fit properly. It's easy to clean out the old one so that's really a non-issue just something to note. ... show more

  • Durability & reliability? Nope.
This happen less than year. Tried reaching out but no response still. Car started losing rpm & pull over at gas station, heard a loud bang & car cut off. Check my aem regulator & now fuel pressure. Opened tank & saw this. Ran new wires & relays in my civic k20 build. Barely ran for 6 months. Have a Volt meter on car & was 13.7 to 14 so 1000% sure it was never a electrical issue. Got a dw pump & plugged straight in & started working. Pump quality & reliability is not the best. ... show more

  • Good performance and thus far very reliable
Was a direct replacement although skinnier in diameter. If you are going to solder onto existing posts ensure you have a good soldering iron to save you some frustration you plan to cut and splice its very easy to do. sits in stock cradle and was an easy swap. for a novice the difficulty level is 2.5 out of 5 wrenches. for someone familiar with electronics and taking things apart its a simple task to complete. Pump is extremely quiet and provides smooth fuel flow. ... show more
