Re: [AMC-list] Fuel pump question

[Joe Fulton <piper_pa20@xxxxxxxxxxx>]

If you look closely at the vacuum pump part of the fuel pump you'll see "inlet" 
or "in" and "outlet" or "out" of something similar on the two ports.   You want 
the inlet side of the vacuum pump connected to the wiper motor.  You can verify 
that it is creating suction by using a vacuum gauge or even just unplugging the 
line at the pump or the motor and verifying that there is good suction.  The 
wiper motors fail with age due to dried grease in the mechanism and flapper 
diaphragms which age and do not seal to the motor case.  They can be rebuilt.

Subject: [AMC-list] Fuel pump question


I am having a problem with the wipers on my '62 Classic; they don't work! They 
move slightly when turned on, but lack enough strength to move the blades more 
than a few inches. I am assuming I need to pull the heater box and rebuild the 
vacuum motor, but before I do that I thought I would check the obvious. The 
vacuum lines look good, but I have a question about the hook-up of the vacuum 
booster fuel pump. 


          Which fuel pump port should be connected to the manifold and which to 
the wiper motor? 


When I look down at the top of my fuel pump, the line from the manifold connects 
to the port on the passenger side of the pump while the wiper motor hose is 
connected to the port on the drivers side. They cross over each other, which 
doesn't really make sense to me. 


          Is mine hooked up like yours or is it backwards? 

FYI, I have the 196 cast iron engine. If some members with similiar cars could 
look at their set up and conform my set up I will be a happy guy. Thanks in 
advance.
