I HAD a Carter fuel pump.
It worked great, was super heavy-duty, and easy to install. I got the one designed for the marine environment, which was a little more expensive. The only problem I had was finding a mounting location. The location I ended up using was not high enough, and while traveling down a Baja road, I broke the Carter pump. One of the control arms came up and whacked the thing really good. The directions require the pump to be mounted in a certain direction, up and down. Thus mounting locations were tricky. Slee said they mounted one back by the rear bumper. I just didn't want to have a long fuel line run.
SIDE NOTE: My 80 does NOT have bump stops inside my rear springs. I believe, if I had the bump stops, this may have prevented my pump from breaking.
Currently I am using a generic transfer pump that I got from Napa. It was a LOT cheaper ($30) than the Carter ($110). The pump rate is around 30 gph. Which is kinda slow. You can also hear more of a knock-knock-knock noise as it's pumping, compared to the whirr that the Carter made. But, it works for now. The Napa one is also smaller than the Carter.
Hope this helps.
