I have a hard time believing that the regulator i at fault. I have replaced the old one, and there i no change from the old to the new, so I think old one was working fine. Maybe the vacuum is not working, but I put new hoses on and there is suction from the engine.
I had the lid open, and there were some ripples/movement of the fuel, but I could be from the running of the engine.
Is there a valve in the return line that maybe is not working?
I think the best thing to do is pull of the tank and check all the pipes inside - right?
Any other good ideas?
