Re: [AMC-list] EFI 196 conversion issues (fuel pump)

Cavitation only wears them bad when it's present a lot, a little of course won't hurt, or takes so long that it's a moot point. But it's always best to avoid any situation that *could* be damaging! A little head pressure for a vane or turbine style pump goes a long way, and below the tank IS the best place to put it, level with the bottom of the tank at least. Mine was level with the top of the tank.

I was gonna say I didn't think they were much cheaper, I paid $165 for my first one and recently priced some Holley pumps at near the same. I checked RockAuto for some mid 90s pumps though, and they are more like $100 on average, with a good many under $50. Hurray for the Chinese and Mexican manufacturers? 

I "found" those East European pumps AFTER you mentioned the source on the strokers list, I think -- definitely after you put me onto it though! I bought the guys remaining stock of 5-6 pumps then sold a couple to others on the strokers list. I had one go out, probably because of placement putting a strain on it, but the other one lasted a couple years -- until the car was totaled. It didn't like getting banged around, made some noise after, so I replaced it with the last spare I had. It ran from 2003 until I built a gas tank in 2006 and used an in-tank pump. I did some research on those pumps -- I believe they were Czechoslovakian, but could be wrong.

yar, this is probably true, but I have seen pics of the extreme wear cavitation causes on vane type pumps and do not want to take the chance.  

Back in the day, the external pumps capable of driving the MPI Jeep systems were pricey, much better priced now.

 The pump I finally found is a eastern Europe pump made to replace Mercedes pumps, maybe even Russian? Very heavy, the only name on the pump is Tat3, Always assumed it actually meant TATE, and the 3 was a flipped E? Who knows, I bought one and it was working well, told Frank and he had found them to, or found them shortly after?
