The ready made insulators may be available but I didn't check. IIRC there had been an earlier discussion where someone else was looking without success so I just went ahead and made my own using Garolite from McMaster. That is a phenolic rod or tube which I believe is similar to the original.
I chose the Hard and Strong (XX) because the diameter I needed was available in that variety and I thought there was a good compromise between price and the max temperature rating. That particular item is good to 265 degrees while others are 235 or as much as 335. It comes in both tubes and solid rods so you should be able to get close to the diameters you need. Unfortunately they only sell it in a length much longer than is needed. My pump has an inside lip surface near one end so I had to get the larger diameter and then turn the end down to match my smaller diameter lip.

Thanks, Howard. My pump also has a lip near the outside edge of the flange bolt hole. Max Merritt lists an insulator kit. It looks like a pair of nylon washers and two lengths of rubber tubing for the flange holes. I ordered a kit. We shall see. Did you make an insulator that goes between the pump and the engine? This would seem to me to be necessary too.

I didn't have to make the gasket type insulator because there was a thick pressed cardboard like piece in a full gasket set which I assumed was the same as Packard used. Don't remember the thickness but was at least 1/16 if not more. Those might be available separately thru Napa or Max.
I did order some phenolic washers to go next to the pump and sandwiched those plus a regular steel washer under the bolt head to farther separate the bolts and pump.

Thanks, I'll see what I can find at MSC.

I have ordered some material from MSC. A foot square sheet of 3/16" for the insulator between the pump and engine and a tube of 5/16" ID and 1/2" OD to make sleeves for the bolts. I think nylon 5/16" washers will complete the kit. I will also see what MM sends me. May have enough material to go around. Thanks to Howard and Dell for your help.

Was the old insulator between the block and pump that thick? The 47 and 56 are about half that so I would make sure there is enough length or contact area on the fuel pump arm to still make a complete motion if you space it out 3/16.

Howard, pump on the car does not have any insulators. You bring up a good point about thickness of insulator. I thought 3/16" thick insulator would provide needed separation without affecting motion of lever. I can check output and pressure after installing. Thanks.
