AEM50-1200 E85 In-Tank Fuel Pump, Black, 4.055 x 1.535 x 1.535 inches

Been using these AEM pumps for years. Never had an issue. Good quality pumps from what I've experienced. I've got 2 peeing a 700hp Subaru flawlessly with radium engineering brackets and regulators. Good to see AEM still going after all these years.

It's a must for high horsepower vehicles. They are super reliable and they're E85 compatible.

Used these in a few E85 conversions over the years and they work fantastic. Quiet, impressive flow. Great pump for most any boosted 4 or 6 cylinder application. I'm sure some boosted V8 and big block guys will probably outflow this pump, but I can't imagine anything with less than 8 cylinders pushing this thing to it's limit. I still have one from 2017 that's going strong. Generally needs only minor modifications to fit into a GM canister.

My Supra makes 700whp with a 55psi base pressure and 20# of boost, meaning that I need to feed E85 at 70PSI. I run two of these pumps in parallel and they do a fine job of supplying large amounts of fuel at relatively high pressure. The first pump does 80% of the work.After an hour of cruising, my fuel temperature rose from 71F to 86F. These pumps can be PWM-controlled, which would reduce this minor temperature rise.

Sightly taller than OEM, so very tight to fit with rubber boot and OEM filter pipe without trimming (can see flex in metal frame). Fuel sock is tiny next to OEM so re-used that instead. OEM harness is plug and play with no need to solder/crimp, although a spare connector is included. Car running much happier - 2007 WRX (Prodrive 270 BHP).

Easy installation. Looks awesome. Can feel the difference. Can hear it work. Gave us little extra rubber hose just in case.

At first this was an excellent pump! I have a 1992 Volvo 940GL with the Bendix Regina engine management. My car only has 1 pump and that's the in-tank pump. I need high flow to ensure proper pressure at the fuel rail so after trying 2 other pumps without success, I tried this one. It worked excellent (at first). A couple months into using I had an issue where it popped my 10A fuse. I read elsewhere that it may need as much as 15A so I upgraded the fuse. This was only a temporary fix as about 6 months after that, it popped the 15A fuse too. Just for s's and giggles I tried a 20A fuse and that popped immediately. I only have 14GA wire running to it and I didn't want to stress the electrical by increasing fuse size again. I went to the tank and used my ohm meter to check the pump. Almost a dead short (0.7 Ohms). Long story short, the pump seized up on me in less than a year. Not wanting to go through this yet again, I ponied up the extra ca$h for an OEM Volvo pump and have been running solid since.To each their own, personally I would have loved this pump to be the end-all solution but I was unfortunate. You may have better luck so take my tale of caution at face value.

my prelude is working again!!!!tried using the non-e85 one and it stopped working after 2 months. not sure what's up with that....unless itsthat damn corn.I understand that the original version should of been ok with 10%, but...went ahead and got the e-85 flex fuel version and it's been working so far, but time will tell.
