If you go to that image and click next, you will see the gasket set that you also need.

I'm not recommending these products or the vendor. Just trying to respond to the question in a kind and gentle manner.

 

I really wanted to run a mechanical pump on my son's 351, but when I put the excentric on, the timing cover would not fit. I guess ther is another style that will work with the larger aftermarket timing gears, but I did not have it, and could not find one. The timing cover was ready to go on right then, so the excentric came off. Of course now we will be using an elec fuel pump.

So, when anyone wants to buy larger aftermarket timing gears, there can be complications regarding the fuel pump...

Which brings to mind,,,, Anyone want to buy a brand new Carter mechanical fuel pump for half price + shipping?

 

my serpentine unit does not have the plumbing for a mechanical fuel pump so I had to get the electric fuel pump (at least the guy told me that before I bought the Vintage unit)
