My son volunteered to get my mother's 37 ready for a wedding late last year-https://www.jalopyjournal.com/forum/threads/wedding-cars.1122452/page-2 post 46 Fuel pump was leaking on the 305, he put a new pump on Friday night and had fuel pressure issues right away. He didn't have a way to check the pressure (I was already on my way to wedding) and no amount of attempted carb repair (Q jet) would cure it. Interesting part to me was this spacer you were suppose to install if pressure was to high. Anybody else ever heard of this before? Saturday morning he got a different pump from another supplier and the car purred like a kitten for around 5-600 miles that weekend.
