Re: [Chevelle-list] fuel problem
There is a bolt that can be removed to hold the pushrod up but it really isn't that hard to line the pump arm up with the pushrod and hold it in place. If you do use the bolt method to hold the rod use a soft bolt and just finger tighten it as you don't want to nick the rod and have it bind. When you test a fuel pump the pressure can be ok but you also need to check the volume, I am not sure what the exact volume should be but a good rule of thumb is a pint in 30 seconds.

Re: [Chevelle-list] fuel problem
Every hard starting SB Chevy I ever owned, had either a weak or bad fuel pump which made it hard to start. Yes pull the short bolt and stick longer bolt which will hold the fuel pump push rod up.

Re: [Chevelle-list] fuel problem
I just recently changed the fuel pump on my 67 327 and tried the bolt trick. Even using a longer bolt that I could physically feel in the push rod hole, the bolt never contacted the push rod; the rod ran underneath the bolt. Wound up having to remove the plate, grease up the rod with some bearing grease to help keep it against the camshaft. I remember it working in the past but didn’t on this engine. ???

Re: [Chevelle-list] fuel problem
I had that problem on my Impala a couple of years ago and discovered that the fuel line had developed a leak back by the tank and would completely dry out overnight. It took two mechanics a week to find it. They kept looking around the engine until we put it on the lift to do some exhaust work and saw the rotten section. Hope your problem is that simple.
