Works perfectly for pressurizing and feeding fuel to my demo derby car from an auxiliary fuel cell. It's very small and you can tuck it away in some nook or cranny easily.

I bought this pump specifically as a fuel transfer pump, to transfer fuel from an auxiliary tank to a main tank. The pump has a decent amount of lift suction to work well for this application. It's heavy, solid and well-built. However there are definitely some issues with this, which buyers should be aware of.The first point is that the terminals and inlet/outlet are not labeled. So just taking this out of the box, there is no indication as to how to properly install it. The manufacturer doesn't include any instructions with the pump either. You literally have to go back to Amazon and look at pictures of the item in the listing to figure this out. That's a pretty big fail.Second is while this external pump is sturdy and reasonably compact, it doesn't come with any mounting provisions. No clamps or brackets and no mounting hardware. So you will have to find or fabricate that stuff on your own.Finally, the inlet to the pump is considerably larger than the outlet. While I'm sure this has some functional purpose, such as to maintain good head pressure, this means to hook it up, you will need two different diameters of fuel line, or an adapter. Simply placing this in-line into your existing fuel line will probably present a problem.

I need 125 psi,this pump only gave me 65 psi.Car won't start.

I purchased hydraulic oil in a 5-gal bucket for my tractor, but the bucket is difficult to pour into a 2" oil fill spout. The hydraulic oil is pretty thick so this pump only transferred about 1gal/minute, but it did the job without spillage (many pumps won't even pump the thick hydraulic oil). The suction side of the pump would only lift the hydraulic fluid about 12" so I had to tip the bucket as the oil level dropped below 1/4.I've also used this pump for diesel fuel and it pumps diesel very quickly.

I used this pump for fuel transfer between two different fuel tanks.... It may be a bit over kill for just transfering fuel but it works great and the different flow rates seem to be spot on for what is in the description of the product 👍. Thank you!

Worked great easy to install.
