Hi All, Had a lot of problems with hot starting of 1300 Doblo, after loads of searching I tracked the problem down to the hp fuel pump, I replaced the pump with a remanufactured pump. A few weeks later it went back to how it was, I removed the fuel regulator from the pump to fine that the oring was chaffed and worn away in one portion, I replaced the oring with one I had in my tool box, I need to replace it with an original as it may not be diesel proof, my question is on new regulators that you see on the internet there are two o rings, one on the front and a second one at the base coloured green, when I looked on the old regulator and the new one it did not have the second green oring, should it have one , and where is the best place to buy new seals.
Cheers Andy.
