How do you replace the fuel pump in a bug?

Answer 1

Lift rear engine cover. Locate the carburetor (sits under black aircleaner) follow the fuel line from the top left side of the carb to the fuel pump. The fuel pump is bolted by 2 13mm bolts to the engine case. There are 2 flavors of mechanical pump, one style fits a beetle with a generator, the other style is for a beetle with an alternator. The pump body is angled differently to clear the alternator body. NOTE: While replacing the pump replace the grommet where the fuel line passes from the tank (in the front of the car) through the engine sheetmetal to the intake of the fuel pump. That grommet is known to fail, engine vibration cuts the fuel line and an engine fire results. Not good.

Easier answer

It's bolted to the engine right above the crank pulley. There are two hoses coming out of it--one to the carb, one to the front of the car.

Another answer

A lot of people have put electric fuel pumps on VWs--they're less expensive than mechanical ones and they work well. I don't think they're really all that safe unless you can figure out a way to wire a relay in that cuts off the pump when the engine quits. If your car has one of these, it's probably bolted to the side of the engine compartment. To find it, trace the fuel line coming out of the carb to it.

Ignore these answer, they dont give much help I think....

another solution is: to remove:

1. Pull hoses from pump and properly stop up ( insert a bolt or such to stop fuel flow and keep debris out of other) 2. Unscrew bolts at the flange ( what holds it on) 3. lift off pump 4. remove push rod, intermediate flange, and gaskets. fuel pump now out.

to adjust pump stroke: ( note ALWAYS install intermediate flange on crankcase BEFORE inserting rod, otherwise rof may slip through flange into crankcase.) 1. Place new gaskets on the crankcase studs for pump and install intermediate flange on top of them. 2. Insert push rod in the flange, tapered end down, to ride on eccentric cam of distrisbutor drive shaft.

( warning+ make sure ignition is OFF) 3. Turn the engine by hand until the push rod rises to its highest point of travel. 4. Measure projection of rod abovew the flange; that is, from tip of rod to upper flange surface measurement should be 0.51 inch 9 (13mm) 5. Turn engine again ( by hand) to bring rod to lowest point of travel. Measure tip of rod to surface of flange. total pump stroke should be about 0.16 inch ( between 4 and 5 mm) 6. Set stroke to correct measurement by removeing a flange gasket or by adding one (or more) To Install: 1. fill lower chamber with universal grease. 2. install pump with inspection cover at left. Attach nuts. (Engine should be warm and not stone cold. use heater if necessary to bring to working temperature) retighten nuts but do not over tighten. 3. reconnect hoses/fuel lines and check seating of rubber gaskets. 4. reconnect battery. (I have a 68 with an alternator mod instead of a generator. this works fine for both.)
