    • Works awesome for 2008 honda odyssey
Model: 13825
Factory fuel pump finally went kaput on our 2008 honda odyssey. This replacemt unit lot cheaper than the factory unit and has been working great for the last 8 months or so. Still going strong. A couple minor mods need to be done to replace the pump since the factory unit is built into the fuel sender. Nothing too difficult though. Took about 2 hrs to remove the fuel pump and replace it including removing the interior to get to the service panel. ... show more

    • pump working great so far
Model: 10912
put into a e85 modded grand prix as a replacement since my $140-dollar aem pump died in 3 years. this one not only fit much better but sounds better too and if it lasts 2 years then that's a much better deal and i can even warrenty it out. im not sure how well it fits an application it was meant for but i only needed to make a small adjustment on my canister to get it to fit but it was clear to me going in that the pump is not made for my car so no complaints from my end. ... show more

    • Quiet and powerful
Model: 13836
I did not use this to replace an already existing in-tank pump, but to retrofit one to replace an inline pump. It is quiet, and outputs stable, high pressure fuel flow. For a great price!

    • Not a easy fit!
Model: 10912
Convoluted tube was too small for fittings. Length of pump was too short for the can, so I had to add spacers for length. If you like trips to the auto store to buy additional parts then this is the part for you. Needs moderate modifications to work properly!

    • First pump died. Good thing I bought 2. Let's see if the 2nd one lasts.

Installed this on a 2010 Impreza. Snug fit. Comes with a lot of accessories. Brought my car back to life. Perfect bang for the buck pump. Edit: It died again after a week. Good thing I bought 2 since it's so cheap. I'll update if the other one lasts. Edit 2: It’s not the pump. It’s the stock hanger’s pins that died due to the higher pull the pump makes. Since the pump didn’t come with instructions, I thought it’s all plug and play. However, be sure to use thicker gauge wires for the pump, and it’s recommended to bypass the stock plug altogether and get a fuel pump wiring kit. ... show more

Pump was a perfect fit for my 93 Grand Marquis. The pump comes as a kit with strainers and hoses. Only issue I had was with the rubber hose, it was too short. Thankfully, I had extra in the shop. Installed pump 2 weeks ago, I'm getting a strong 42psi at the fuel rail. My previous pump was worn out letting me down with 29psi. ... show more

    • Works great, but had to slightly modify my RX300 bottom plate.
Model: 10910
First and foremost, assemble your whole unit gently if this is going into an in tank fuel level sender and pressure regulator all wrapped into one unit like I found myself doing in a 2000 Lexus rx300. There are some small tabs in the bottom of this pump that protruded farther than the thickness of the rubber cushion so I initially tried cramming it together and actually broke my new fuel filter. So to alleviate that I replaced the fuel filter and used a soldering iron to melt slots in my bottom cap to accommodate the pump and have it still held quite snugly, but not so tight as to break another new fuel filter. Works amazingly now. Being a 25% higher flow than my stock pump, I expected it to be slightly louder when running, and it is. Not excessively loud by any means. Similar to the sound of the stock fuel pump in my 2005 Jetta. Just a couple items I thought someone may appreciate knowing ahead of time, but it truly is exactly what I wanted despite my issues with my application and for functionality and performance I still gladly give it 5 stars. ... show more
