    If you are purdy sure you have the pump, lines ect in the back doing what they are supposed to.

    Then look at the front.

    There is a short rubber hose from tank to metal tube. It can be rotten and sucking air.

    The pick up in the tank has a small metal screen on it. It can be plugged.

    The gas tank can have some rust in it. Plugging up the small screen on pick up or the metal line through the tunnel.

    The vent on the gas cap or on later models filler neck can be plugged up. Caint get gas out without air going in.

    Usually problems in the front act like running out of gas. But only at speed. Idle and low cruise. Drive on highway and run out. Stop and crank and crank until carb fills back up and it goes again.

    You're trying to fix something thats not broke. Whether you can see fuel in the filter means nothing. If you pulled the top of the carb off and have gas its not your issue. The car runs and drives down the road then its getting fuel. The hot start problem is not from lack of fuel. Its possible I misinterpreted something if so my apologies. To get the car started do you have to pump the pedal or hold it to the floor. When it starts does black smoke come out?

    Well some like a single carb over dual carbs. I run dual carbs on my trike, but at times they seem like more trouble than I wanted, LOL

    Now a fuel pressure gauge can be borrowed from most part houses now. At least on the west cost area they started a tool loan program from the local auto stores.

    No way am I a specialist or a carb mechanic, I just have always played with them and kept my vehicles running.

    I have only ran an electrical fuel pump on this trike, so do not know how a manual pump fuel flow would look in the filter, but it would be spurts of fuel I would think, but one would think as the pump delivers more fuel the filter would fill up as the carb can only use so much fuel at one time, if the bowl if full and at idle, I can run for over 10 minutes at idle before I notice a idle rpm issue...........just means it wants more fuel setting in the carb bowls.

    Losing lot's of fuel, not sure were it is going, it can drain into engine oil, so pull the dipstick and smell the oil, if it stinks like fuel to much, drain and change the oil, but it is best if you can resolve the fuel issue first, other wise you might have to do a few oil changes, okay I had to do it that way.

    www.thesamba.com is a VW site, old school VW owners, off roader's and restorer's offer lots of help and you can find a lot of info from previous members issues. I have found some help on issues over there, just wish I knew more about your carb to help you more.
