I've had an intermittent and temperamental fault with my 1976 Kombi fuel system for a few months. I'm hoping to drive from Wellington to Taupo for the NZ VW Nationals at Easter, but it will be an anxious trip if I can't get the fuel issue sorted. The engine is a 2L with the standard twin carbs and a mechanical fuel pump. When its running it goes really well. Three times recently however I have been driving along a highway with the bus chugging along quite happily at 90km/hr when suddenly I lose acceleration, no power when I put my foot on the gas, and it stutters to a stop while I'm frantically try to pull over safely. First time it happened I had to get towed (about 15kms) when it just refused to start. I'm no mechanic, but with some help I put in a new fuel filter. The engine started right away and I drove around locally for a week or so. The fuel starvation problem happened a few more times while I was driving (on test runs) for say an hour or so out on the highway. On those occasions I was able to wait for a few minutes, start up , drive off and (with bated breath) get back home. The second time I coaxed it home and had fitted a new hose from tank to filter, drained the gas tank and removed a few small flecks of perished rubber (from the old fuel filler elbow which I've had replaced). Yesterday after losing power out for the third time out on the highway I managed to start it up no problem and drive home again. It does seem like a fuel issue rather than electrical to me. Any suggestions why this should happen? Is there an obvious solution as to why its an intermittent fault? I'm thinking the next step would be to get someone to dismantle and flush out the fuel pump and or the carbs? Any advice would be appreciated. And may the best team win in the cricket.
