    It hasn't been good since the economy took a crap, I have always done good, but it's been realy bad, this year has been the worse, I usually do good in the winter, have done this for over 20 years excep for two that I move to Vegas in 91 to 93 and this winter was the worse I've ever seen, I just hope that there is a change in the white house or else a lot of us are going to hell.

    Did a few more things to my B model earlier this week. It got a new turbo, and I changed the fuel feed system to the injection pump.

    To be exact it's a 80 GMC Astro, prolly the worst excuse for a cabover ever.

    why is it that you plumbed feed right into the side of the injection pump? what was the purpose of this BIGGER line more volume? Where is the stock inlet on the pump go anyways and you changed to a -10 line instead of the factory -8 correct?

    also were you showed a pic of the filter and mount whats the red hose going to looks like a pump of somesort?

    is this a day cab astro or sleeper? any pics exterior.

    The red hose comes from an electric pump, that is all I use. The original set up was -8 to the old filter base, then -6 from there to the IP. The original line feeds into the front top side of the pump, if you ever have a fuel feed problem it will starve cylinder 5 and 6 first. IMO this way feeds everything equally.

    Truck is a sleep truck, I don't know if I have pics or not anymore.

    Post up a pulling video.

    I was wondering how an electric fuel pump would work compared to the transfer pump. think it would hold up in every day use?
