Fuel pump replacement is very important. If the engine does not have a functioning fuel pump, it will immediately "starve" and stop functioning. When fuel pumps are not replaced properly, the whole system is damaged. Although it might sound difficult, fuel pump replacement is easy. Depending on the kind of fuel pump
How to replace:
1. The fuel pump is tested to be sure it isn't functioning.
2. Should the fuel pump be faulty, it is removed from the tank through an access panel above the tank in the passenger compartment.
3. When no access panel exists, fuel is first drained from the tank and then the fuel tank must be lowered from the vehicle to gain access to the pump.
4. In all cases, fuel pump supply and return hoses, as well as EVAP system hoses, and electrical connections to the pump must be removed.
5. Once the pump is out, any reusable brackets and pick up screens are attached to the new pump, then the new pump is installed.
6. If the fuel system uses an in-line external filter, a filter is often replaced. All hoses and electrical connections are re-established.
7. Fuel is added to the tank and the engine is run to test for leaks.
Is it safe to drive with a fuel pump problem?
Usually, it's still safe to drive, but the pump may lead to an overheated engine and catalytic converter. Complete fuel pump failure can leave you stranded out on the road, but many times a car won't start before initially driving. However, if the fuel pump problem involves leaks of gasoline or vapors, it is unsafe to continue driving, and should immediately be checked by a qualified mechanic.
