    • Good pump.

Works good. Easy wiring. Fit good as well as good value for the money. Pretty quiet overall.

This pump ran around 5000 miles before it quit, I emailed the company regarding their lifetime warranty and have heard nothing, the company claims to be American, but the pump comes from Ching Chang China!

    • Was a great solution for me.
Size: KEMSO
This was a super easy installation on my 1988 Ford Thunderbird Turbocoupe. It provided plenty of fuel flow to feed all of the modifications that had been done to the car. I only kept the car for about a year after install so I do not know how long it will hold up.

    • Seems to be good pump
Size: KEMSO
Haven't test done any test runs yet, but it made the vehicle run so far, all the hoses are wrong for an 88 mustang, little ones to short and won't bend well and long one is way to long. No lower rubber isolation pad for it either.

    • Poor quality
Size: KEMSO
Installed on a 1988 Dodge ram B250. This pump ran about 2.5 gallons of fuel before the pressure on it dropped so low it barely dribbles out of the fuel line right off the tank. Had to pick up a locally supplied external pump to get the fuel pressure back up. I will not be dropping the tank on this van again. Waste of 40 bucks and lost labor hours. Will contact Amazon about getting a refund. ... show more

Size: KEMSO
Failed in one week of use. You pay for what you get sometimes. I would recommend Aeromotive instead. Not cheap, but also not overly expensive, but gets the job done.
