Good advice. I’ll put in the fuel filter later today, they didn’t have one on the shelf at the auto parts store last night.

I’m also thinking a fuel pump would be a good idea, given that it’s so damn hard to access, and I know I’ve never replaced it, it’s a bit shocking, but this might be the original fuel pump. You need to lower the fuel tank to do it.

The bizarre thing in all of this is that every change I’ve made has resulted in better performance but the hesitation thing is still there. Yesterday I put in a new stock GM coil. It’s an odd shaped thing, it’s not the big cylindrical item you commonly see. Would be a lot of work to attach anything other than the stock item. It ran noticeably better, but still not perfect. Wasn’t very many weeks ago that I was astounded at how well the engine was running. Apparently I had some deferred maintenance items coming due.
