Older model cars with carburetor engines use low stress mechanical fuel pumps to pump fuel from the fuel tank to engine. Electric fuel pumps: These are vvt control valve on newer fuel-injected engines. Installing a new fuel pump might enhance engine functionality just be confident to know what sort of fuel pump is best-suited for your particular automobile. Automotive fuel pumps will normally fall into two distinct categories: mechanical and electrical.


Mechanical fuel pumps are "puller" pumps. Some ECUs could also be programmed to shut off the fuel pump if they detect low or zero oil stress which would indicate an impending mechanical failure. Reduced the fuel tank and take away the fuel pump assembly. The pressure at which the fuel is expelled from the pump is therefore restricted (and consequently regulated) by the force applied by the diaphragm spring.


We generally recommend this fuel pump more than the F90000274 when the planned technique pressure is intended to stay below 80 psi (base + increase stress). Contaminants have an effect on the functionality of fuel pump and for that reason the engine. A possible hazard of a tank-mounted fuel pump is that all of the fuel lines are under (high) pressure, from the tank to the engine.
