Review on 🔋 Fuelworks Diesel Fuel Transfer Pump Kit - 10GPM/40LPM Portable Heavy Duty Electric DC 12V with Alligator Clamps - Includes Aluminum Manual Nozzle, Delivery Suction Hose, and Filter (Not For Gasoline) by Michael Gutierrez

I'm sorry for those who checked and received a bad block. Mine works great, installation was easy, nothing else needed. I've been pretty liberal with the teflon tape, although tolerance seemed a little loose on the NPT fittings, but no side effects. The only complaint is that the bypass pressure seems a bit high when the valve is closed. I don't know how, it's just a small 12V pump. but there is something to consider. I'm convinced the filter I installed on the line is junk too, but it leaked when the handle was closed. I put the filter back in place and while it's working I'm watching the leaks very closely. It should be noted that the mesh filter is useless. It's so high you never get the last 1.5 inches of fuel in the tank. In some tanks this is quite a lot of gas. I left out the strainer and cut a few slits in the suction line to flatten the suction tube and installed an inline filter upstream of the suction side pump and it works great. The system has enough main flow to vent and fill the filter even when it's not on the pressure side. (Yes, I have two filters. Overkill? Maybe, but a small pump can pump diesel through both).
