Fuel Pump

I replaced mine a year or two ago with the smaller pump plus adaptor, both
purchased from Scott, @ SJM Autotechnik <www.sjmauto.com>.  No other new
parts needed.

I don't recall all the details, but I used the old nylon hose, cutting off
the attaching screw connector to the old pump, and a 6" piece of rubber fuel
line and two mini hose clamps to connect between the nylon hose and the new
pump's hose barb output.  Works great.  Just be sure to use down the tank to
E before starting.  No special tool needed to remove and replace the 1/8
turn spring ratainer.  I must have reused the old electrical connection
wiring also.

Don't try using a CIS pump on the 20V AFC system.
