Which timing chain for fuel pump eccentric?

Nick,

I used the ford motorsport double roller timing set in my 289. The one piece fuel pump eccentric that you have will work perfectly. Most of the issues that I have had with eccentrics have been with the two piece ones not spinning properly on a cam gear designed for a one piece. So, you could probably use whatever timing set you want with the one piece. Hope this helps.

you have to buy matching timing set to your eccentric
or new 2-piece eccentric to your 98 timing set.
