The first time I did a fuel pump on a Corvette w/ A/C, looked the situation over & pulled the right front tire & used long extensions. Have posted that tip many times. Esp. for A/C.

The biggest problem is the pushrod slides down. Couple of ways to make it easier- one is to turn the engne so the pushrod is "up" all the way and install a long bolt in the upper hole in the front of the block, install the pump, and put the short bolt back in.
Other way is to take the pushrod out, slap a load of grease on it, then put it all together. Either way, make sure the pushrod is up, and don't pull the pump into place with the bolts.
I've also fished the pushrod up and held it with a long feeler gauge while I put the pump on- this one takes some practice.

1.) Rotate engine so pump pushrod is in the "UP" position.
2.) Remove right-front wheel.
3.) Use long fuel pump bolt [finger-tight torque only] to hold pump pushrod in "UP" position until you re-install the pump. Then remove and use to bolt pump back up.
These (all mentioned above) are the keys to making an 'easy' job of it.

Yes, the grease is a fast way to do it. Many of these are well known so I only posted my contribution.
I normally keep a short telescoping magnet in my shirt pocket.
It seems to me that Glass Act was first & only to post this tip.

On my 70 L46 there was a return line on the original fuel pump going to the tank. New pump had no such provision. I ran a small line off the supply to the carb connected to the return line which seems to work OK. Have only driven about a hundred miles on it.
