Re: blazer just died while driving home
So I replaced both filters (1 inline filter between the tank and pump, and 1 little filter in the carb housing). Both looked fine, but replaced them anyways. Then unhooked the fuel line at the carb and put it in a gas tank and turned the key on. It pumped 1 pint in 30 seconds, or 1 quart/minute. I thought that was plenty of fuel, pretty good pressure. Then I hook everything back up and go to start it, and it won't fire. And the pump is really loud when compared to normal. So I suspect a fuel pump (even though it's pumping good flow rate out the hose)...kind of confusing.
My pump was an "Automotive Electric Fuel Pump, 2.5-4psi". Has several numbers on it, 6F96, AU2635, and E8016S. Does any of this sound correct? Can I just get any 2.5-4psi pump for a replacement then? My Haynes manual says the 2.8l should be fuel pressure of 7psi. Do you get lower psi for the 3.4l engine swap then?
