Stumbler-
Harbor freight internet store is a good source and northerntools.com has a good selection too. Don't do what I did. I bought a very good quality and very expensive ($250 on sale) metal fuel pump. I'm sure it will last a long time if I take good care of it BUT it is hella heavy to lift to and from drums. It pumps fast, 15 GPM so I'm in and out of there in 10 minutes (includes set up time) for 20 gallons.

It is 25 lbs and I don't have a lot of upper body strength unless I lean closer to the pump before lifting it up. Do I want oily, recycled WVO on my torso? UMMMMMM No! I'm not that kinky.
Buy a lighter pump that has good construction and auto shut off that protects the pump from overheating. That's a good investment.
Hope that helps.
Frankie
