1966 122 B18D with glass bowl (Canadian) fuel pump.

Were there different thickness phenolic spacers used with different fuel pumps?

My '66 came to me from the original owner with the glass bowl type fuel pump. The pump seemed to be working okay but there was a bit of oil seepage coming from the underside of the pump area. Last week I put new gaskets on both sides of the spacer but the oil leakage continued.

The car had also developed a habit of needing a lot of cranking to get started in the morning. Once started she runs fine all day and will start right up on the way home from work after sitting for eight hours. I figured that the fuel pump might have a very small hole in the diaphragm that might allow fuel pressure to drop at the carbs overnight.

Sunday a spare Pierburg pump was installed. In mating the new(er) pump to the phenolic spacer, it became apparent that the spacer was cupped. So _that's_ why there was oil leaking down there! I used some high temp RTV sealant and carefully snugged the two mounting bolts but a dreaded cracking sound came to my ears just before the bolts were good and tight.

My 544 is no longer available for reference but I could have sworn that the spacer on the 544 was a bit thicker than the warped one on the 122. The 544 had a Pierburg pump the entire time it was in my possession.

For now, the RTV is sealing the crack just fine and the spacer should be okay until there is any reason to remove it. My plan is to rebuild the glass bowl fuel pump. Are there different thickness spacers between the two types of fuel pumps?

Thanks much,
