Fuel Pump Problem
i have 86 blazer. when i turn key on i hear the fuel pump prime but it never gets fuel to the regulator at engine. i can hear a gurgling noise at tank. any ideas? pump bad? i put 3 gallons in it so it should have plenty to get to engine.

Re: Fuel Pump Problem
Is it the stock pump and stock wiring harness to the pump? |

Re: Fuel Pump Problem
I dunno, did you try taking the cap off? Maybe the vent could be clogged or something?
BTW I see in your avatar you are carbed, do you have a return style regulator? Last edited by zx9rgreen : 10-23-2009 at 11:40 PM. |

Re: Fuel Pump Problem

Re: Fuel Pump Problem
Sounds like your fuel pump came loose from the sender or the hose connecting them split.

Re: Fuel Pump Problem
Man I agree with above loose sending hose . Hey maybe try venting off air from the fuel rails it might help (that sometime happens on our aircraft then boom fuel spray with a lot of smoke)... lol ill stayed tuned to see what was the culprit.
good luck |
