How do you size a mechanical fuel pump?
Fuel Pump Specs Defined
- 500 X 0.5 = 250 lbs./hr. A gallon of fuel weighs 6 lbs. To get gph divide lbs./hr. by 6.
- 250 lbs./hr. ÷ 6 = 41.67 gph. A liter of fuel weighs about 1.6 lbs. To get lph divide lbs./hr.
- 250 lbs./hr. ÷ 1.6 = 156.25 lph. You need the minimum flow rate at your fuel system’s operating pressure.
What is a facet fuel pump?
Facet fuel pumps have low power requirements (about 1 amp at 12 volts) and operate without troublesome seals or diaphragms. The compact Cube Style pumps are designed for moderate fuel requirements, typically feeding engines up to about 150 horsepower.
Do mechanical fuel pumps have a weep hole?
Most mechanical fuel pumps have a weep hole on the bottom of the unit. When the internal diaphragm leaks, fuel escapes through the weep hole to notify the vehicle owner of a malfunction. This is one of the more common fuel pump problems found in classic cars that are between 30 and 60 years old.
How do I know what size fuel pump to get?
A good estimator of volume to power is approximately 10 hp per gallon or 2.64 hp per liter. For example if your pump flows at 50 gph it should be able to support a 500 hp engine (50 x 10 = 500). However, to actually know the gph you must also consider the fuel pressure required for your engine.
Are Facet fuel pumps self priming?
Facet/Purolator Cube Fuel Pumps are self-priming with a dry lift capacity of 120 inches. Two universal models provide complete coverage for all low and high-pressure carburetor applications for cars, vans, RV’s, and light trucks, in addition to many diesel applications.

Why is my car not starting after replacing fuel pump?
Such could be due to a big vacuum leak, an air induction fault like a stuck idle air control valve or, considering fuel, could be due to a failed temperature sensor that must be working properly to signal the PCM to enrich the mixture on cold start. Other common faults are defective spark plugs or a defective coil.
