Review on Airtex 4886 Fuel Pump by Noe Spooner

The notch for the bolt that holds it is too small for the bolt, so it's almost impossible to tell if it's in the right place. The shaft that drives the pump is longer than a standard pump and will rupture the pump diaphragm with prolonged use. The pump leaked almost immediately after installation. It's best to just use a low-flow electric pump. You can no longer buy a good mechanical replacement. I heard these pumps were good until they were outsourced.
