1988 K1500 Fuel pump

[cpjonesman]

I've been reading some recent post about fuel pumps. I installed a new pump exactly one year ago but it has stopped pumping enough pressure to crank my 350. I bought it at Autozone so I assume it was a Master brand, which most everyone in this forum really discredited the Master brand. Family members had borrowed the truck for most of the last year as their car had died and they rarely put in more than a quarter tank of gas. This could have burnt the pump in this hot Georgia summer. Some in this forum suggested Delco or Delphi. Has anyone had any luck with Bosch? I used Bosch electical parts for years with very good success when I rebuilt air cooled VW's but that was back in the day... Does Bosch carry a good reputation with fuel pumps?

I would stick with Delco or Delphi--seems that most have better luck with them.

Delco is the best. I heard lotsa horror stores about O2 sensors by bosh, some other parts as ignition modules make your car loose perfomance and MPG, plus they fail real fast.
The only reason that the pumps fail is not really from frying them (that would be in extreme cases), but mostly because the bruches in the motor are too short and wear fast especially if you run low on gas. Its really hard to fry a pump and if delco made them with extra long bruches they would not have a chanse selling those spare parts. The same thing relates to trans am headlight motor gears made of plastic and poor relay designes, etc.. Or they could have at least made the pump and the brushes more accesible. Why replace the whole fuel pump when a pair of $2 brushes will do the same? Most of the parts that fail on GM cars are of poor design, otherwise they could build them to outlive any other brands.
