I can't say that i ever got into many of the two stage fuel/vac pumps for repair. Had several cars with them and they were used as late as the early 70's especialy on bottom of the line AMC products of which i had owned at least 6. Never had one make it over 25K miles.
I remeber one AMC/Jeep mechanic indicate that backfire thru the intake would shorten vac pump life but i really don't know. When they went bad i just lived with it at the time especialy since i lived in rather flat level michigan at the time. The AMC 2wo stage pump was about $80 back in the early to late 70's. A standard pump about $7 - $15.

The only nice Gremlin i had was a 74 Levi's Gremlin. Out of the 6ix AMC products i owned it was the only one with electric wipers. The rest were vacuum rangeing in years from 1965 - 1973. They were all very low mileage, one owner cars when i got them. Otherwise, i would not have bought them. COuldn't hardly give a nice used AMC product away back then. So they were CHEAP.
