Default Re: 1966 And Later Fuel Pumps

That's a good question. The non-serviceable '66 and newer pumps all have the straight arm. I believe at some point the mounting bolt holes were changed to 5/16". I think the curved arm pumps were very early, maybe '60-'62. Couldn't say if the difference was the fuel pump eccentric on the camshaft or the timing cover.
