Folks
Been driving the old bunky 4-door now for about 4 weeks and its been pretty reliable aside from a dead alternator and regulator, which was from being drowned...
But Ive got a confusing problem that has left me stranded once already.
After sustained high revs, (doing 100-110kmh), the motor runs out of fuel. Pull over to the side of the road, let it sit for about 10 seconds, and then it starts and runs fine, and I can be back at 110khm straight away without problems.
At first I thought that it might a be a blocked fuel filter or crud/water in the fuel tank. Both were possible since the car before I bought it had been sitting a lot in Maggot Creek.
Replaced fuel filter and pulled out the fuel tank. Flushed tank and even had a captain cook inside with my borescope to see if there was anything obvious. Interesting that nothing of any real note came out, but the drain tube was packed full with silt!
It ran fine this morning to work (about 90 mins with 2/3 at 100kmh), but it died twice on the way home this arvo.
Could the diaphragm on the fuel pump but just not quite pushing enough fuel and then just run dry?
Straight after the car stops, I find the fuel filter seems low or nearly empty.
A guy today at work suggested that it might be an internal carby filter/guaze that is blocked? I didn't know that the std 1000 carb had an internal filter.
Another suggestion was vapour locks in the fuel line, but its not hot yet. If this is happening now, then the car wont be drivable in summer as it will simply run out of fuel all the time.
Anything else worth checking?
