Re: [AMC-list] Fuel pump question

[Matt Haas <mhaas@xxxxxxx>]

This page on my site has info on how to test the pump: 
http://www.mattsoldcars.com/RestoreAmerican/vacuum_wiper_motor.shtml . I 
also have several pages showing a fuel pump rebuild starting at 
http://www.mattsoldcars.com/RestoreAmerican/fuel_pump_rebuild/index.shtml . 
My wiper motor and fuel pump are a little different looking from what 
you but they are basically the same on the inside.

As far as testing goes before you start replacing/rebuilding stuff, also 
make sure that there isn't a problem with the linkage itself. You'll 
need to disconnect the wiper linkage from the motor to do this. Once 
it's disconnected, move the wipers through a full sweep. They should 
move pretty evenly and smoothly.
