Review on 🔥 MegaFlint HEP-02A: Universal 12V Low Pressure Gas Diesel Electric Fuel Pump (2.5-4 PSI) - Efficient Performance for Various Applications by Brion Pine

vibration type fuel pump is universal. It has two wires for positive and negative power, which is very convenient when installing old devices with positive grounding. Many fuel pumps use a metal case for the negative terminal and only have one wire (the positive terminal) that just won't work if you install it on the positive ground system. Imported (of course) but works well on a 1963 Allis Chalmers HD3 bulldozer for loading diesel into filters and pump injectors.
