    When changing a fuel filter on a carbureted truck, can I simply pull the hoses and swap in the new filter? Any steps I'm missing?

    Good question. No, just go ahead, and do it! The little bit of air that it accumulates, should vent itself without causing an air lock! I've worked with a few guys that like to soak em first in fuel, or fill em first, then install them! I've only filled them with fuel, when I'ts a diesel, so as not to cause a vapor lock! Some diesel's(most) can give you a fit with that!

    Yeah, you should be good to go. It might conk out before the fuel gets to the carb, but it should start up quick enough.

    This is the exact question I wanted to ask. I took delivery of a 1995 Hijet yesterday and am servicing it before stressing it too much. Oil filter, oil and air filter are pretty easy, but I had the same question about the fuel filter.

    It sounds like it is pretty straight forward, but should I clamp the hose coming from the tank before pulling the filter? And is soaking necessary in a non-diesel engine or can I just plug and go?

    And does anyone know if the filter is in a housing or can I just connect the one I bought? It is a correct one for the truck. Thanks!

    Short answer, just pull the hoses and plug in the new filter. Just to play it safe, I did put some fuel in the new filter before installing, but it really is not necessary. Assuming the filter is external, it is not in a housing, again, just pull off the hoses and replace the old filter with new, just take note of the direction of fuel through the filter. Most will have an arrow indicating this on the top of the filter.

    The issue I had with my truck was the pickup sock in the tank. The tank has fine silt in it that when driving would get shook up and suspended in the fuel. The silt would plug the sock a s starve the engine of fuel.
