Review: Durabale - Strong & sufficient!! Also not as expensive as I thought I'm definitely buying more!!!
Review: Does the job it's asked to - The pump pumps at a perfect 10 gallons a minute and a half, making sure the air pressure is around 95 psi, and it does transfer waste oil very well. I have had the pump for three years and it has gradually slowed down. It is easy to disassemble and clean but the parts wear out. I have been trying to find a rebuild kit to replace some of the worn parts but can't find anything.

### ⭐⭐⭐ Get what you pay for
*by A***L on July 10, 2024*

Good news is that it works,bad is that it functions like a cheap pump and doesn't stand up to steady use as you would expect from a aodd pump. Not horrible, but better to save up for a AOD from Ingersoll.
