    Ok, Im pissed [​IMG] last week fuel pump gave out on the highway had to get a tow home. Yesterday, I had enough time to replace it with one with a lifetime warranty from AutoZone [​IMG]. I get school ok this morning, but on my way home it stalls, get it started again, go down the road for approx. 2 minutes and it stalls again. Did that 3 times till I got to a side street and had to get a another tow. I'm pretty sure that it's just a poorly made pump that's giving me hell, but I will test it tommorrow. My question is what do yall think is the best mechanical fuel pump out there(Hollley, GM etc) Thanks.

    I checked out your profile and noticed that you have a 305. In case you didn't know, 305s are well known for a wearing out the cam lobe that runs the mechanical pump.

    I had a bout of fuel problems 6 or 7 years ago, and after going through 4(YES...... 4!!!!!!) pumps in about 6 months, a buddy suggested I scrap the mechanical pump and go to an electric pump. I installed a Carter 2-stage pump back by the gas tank and haven't had one problem since........

    Thanks for yet another reason why 305's suck [​IMG]
    How difficult was it to install the electric pump.

    The pump itself is a piece of cake to install- the kit comes with a bracket that can be screwed/bolted to the underside of the floor or a framerail, for example. The pump is attached to the bracket and then the fuel line has to be cut and attached to either side of the pump. Carter recommends installing an in-line fuel filter between the tank and the pump, too. I had a buddy wire the pump because me and electrical things don't get along[​IMG]!!!!!!! You can either keep the mechanical pump in place or eliminate it- I removed mine and bought a little chrome plate to cover the hole on the block. I'm not sure which set-up is better........

    I found that my overall performance increased with the electrical pump, and the little hum coming from the back of the truck is kinda' cool too!!!!

    FYI, the closer the pump is mounted to the gas tank, the better.

    Find an AC Delco mechanical pump and try that first. I have had cheap new pumps fail pretty fast.

    Just so you guys know, two of the pumps I replaced were ACDelco, and two were less expensive parts-store pumps. In the end, the only solution was the electric pump.
