I have installed a new mechanical pump on the Pinto and not getting any pumping action. The plunger is 2" long and there is a 1/4 spacer. I have been suspicious of a weak fuel delivery with the old pump, thus the new one. I understand there are two different length plungers as well as different thickness spacers. Anyone know the correct dimensions or should I just eliminate the 1/4" spacer and see what happens?
Thanks!
