Thanks for the advice to all about the fuel pump. I even got a call from George Riehl offering assistance! It was a combination of the pushrod having fallen downwards, and the tight clearance of the rearward bolt that caused a minor headache in replacing the fuel pump. Also, George strongly recommended that I replace the pushrod, as he explained that it wears down, and does not allow the fuel pump to stroke fully. He said it is a normal NAPA item. The car is now running fine! Again, thanks. John Spiers. "John J.

One trick that has worked for me in the past is removing the pushrod completely (there is a fitting that threads into the block that must be removed first, then the pushrod drops down out of the block. Then put grease on the pushrod, and stick it back up there, the grease will hold it in place.

I'm having a heck of a time putting on the new one - I compared it to the old one, and everything is the same - bolt pattern, lever length and angle, yet I cannot thread both bolts in, especially the one more rearward. Am I missing something obvious? If I tighten the 'more forward' bolt, the rear one will not align, and the whole pump appears to cock somewhat.
