Perkins idle problem
I have a Perkins 6.354 in my 73 F250. It was running pretty well until I intalled a new injector pump. Actually, it ran much better after the new injector pump: easier starting, less smoke, more boost... except for this: after driving around for a bit it starts idling rough. Maybe the new pump is not at fault, it could just be a coincidence. I have been suspecting air in the fuel and today I installed a piece of clear hose on the return line. The returning fuel does not look aerated though this doesn't rule out air bubbles in the inlet fuel. I'll install a clear section in the pickup soon, but I'm getting pretty frustrated. This new pump is so much better than the old one in all other respects that I really don't want to put the old one back in.
Any Perkins or Lucas/CAV experts out there?
