My '82 has a mechanical pump toward the front of the lower part of the engine on the driver's side. If yours isn't there it's an electric pump, probably inside the gas tank.
A fuel pump inertia switch is a safety feature that most of all street vehicles these days have, what it does is incase in a vehicle accident it shuts fuel pump down and will not allow it to pump fuel until it is reset, sudden fast or hard jolts may also trip switch. And since you are on a Ford question site, if your looking for this part it is located ussually on passenger side up under dash close to floorboard just pull back piece of carpet and ready inertia switch and if not there, lokk in trunk.
There are many ways to drive the fuel pump. Some are electrically driven, some are mechanically driven.
i think its underneath the engine
My guess would be the fuel pump. I dont know how to change it, because i havent had to replace the one on my truck yet, but i would guess the fuel pump.
The fuel feed system refer to those parts which work together to provide a constant supply of fuel to the engine. The basic parts are: Fuel tank, fuel filter, fuel lines and hoses, fuel pump and carburettor or fuel injector. I do not like how the question is phrased though.
bad fuel pump bad fuel pump
On mine, it is located behind the passenger side headlight. You need to pull the headlight out to get to it.
Electrical
in the tank.
You need to be more clear as to which "fuel pump" your wanting to know about. The Fuel Injection Pump, or the Fuel Lift Pump ??!!??!!
On my 1989 E350 motorhome, I had a weak fuel pump near the fuel filter. I replaced that and the problem went away. The pump in the tank was fine.
The 1986 ford f150 has two fuel pumps. There is one pump mounted inside of each fuel tank.
on the tank its a pop out button
passenger side below dash
Yes, the fuel pump is inside of the gas tank in a Ford F-150.
in the tank
Your fuel pump would be located in the gas tank. It is mounted on the pick-up tube/sending unit assembly.
