EFI – Fuel pump fuse

Posted by:

PURPOSE
The fuel pump fuse is designed to operate within a specification of between 10-15 amps and will break when it’s overloaded.  A fuel pump fuse continuing to break is not the fault of the fuse but is designed to protect the wiring looms in the fuel pump circuit.

THINGS TO LOOK FOR
A breaking fuel pump fuse could be an indication that it is being overload.  This may also happen when running out of fuel.  A fuse breaking more than once a year is a fuse letting you know that it is being overloaded and must be attended to.
IS IT EXPENSIVE TO REPAIR?
the fuel pump fuse costs only 50 cents but the cause may be a short circuit in the wiring of the fuel pump.  This may require the services of a good auto electrician.

TEMPORARY REPAIR AND LONG TERM REPLACEMENT
If  you’re on the road and the fuse has blown it is usually 15 amps.  At your risk you may try 20 amps but this is only a temporary repair as the wiring may overheat costing you more than just a pump.  If the 20 amp fuse blows, protect the wiring and call a tow truck.  It’s a bigger problem than just a temporary repair.
