Review on 👍 Mikuni 14-2220 Fuel Pump Review: Top Single Rectangular Model for Optimal Performance by Aaron Ethridge

Two reasons you might need this: - Your tank, or the one you have just installed, will deliver fuel less than 10cm above the carburettor float bowl. This ensures that all fuel can get inside. Do you have a motorcycle that was built after 1983? The EPA valve on the tank needs some vacuum to allow air to flow past the fuel when you use it. At a certain low fuel level it is not hard enough to open this valve and your engine will stall with gas left in the tank. This pump can open this valve all the way down. Almost all electric fuel pumps work with excessive pressure and overflow your float chambers. This one is spot on. The vacuum boost is negligible and requires no power.
