bmking16 Posted August 7, 2021 Share Posted August 7, 2021 Hey guys the rack on my 87 with the AMBAC 300 injector Pump PLM4503C3BR is stuck. Any ideas how to free it or is there a replacement pump for it? I can't seem to find any documentation anywhere on this pump.

JoeH Posted May 16 Share Posted May 16 Shame he never got a response. Does @fjh or @Joey Mack know how? I thought a cover had to get pulled on gov housing or something to get it moving.
