Pump Description:

The first obvious thing to note is that the fuel pump is very small. The overall length is 96mm and the diameter is 38mm. Other than the size, the pump is pretty normal. It features a single stage, single row turbine impeller, internal check valve to hold system pressure and a spring and disc style PRV (pressure release valve). The connector is not a standard style. When tested, the pump operated very quietly and smoothly drawing very little current, but also flowing quite modestly. The PRV begins to opens at 50psi which is interesting given that the internal regulator is set for 58psi. The PRV does not bleed off a lot of fuel so effects on flow are pretty minimal.
