Got home last week after 6000 km mostly on vege oil. Car developed a problem, wouldn’t start when hot on diesel and finally refused to start at all unless given a small dash of petrol on air filter element. Then had trouble stalling when revs dropped below 1200. That was a major hassle once we hit heavy traffic crossing the city from Nth to Sth. Now fixing the original pump which I will take to diesel mechanic to get adjusted and tested. One in car has done 65000 kms since I swapped the original for it. Had to reassemble it after Diesel shop had declared it dead and delivered it back to previous owner in pieces in a big plastic bag.
