Re: Pair of Diesels fine in morning, won't rev past 1,500 in afternoon
Try again on a full Tank, (eliminate that or not) was it fine before service, what was serviced. Most likely starvation but many other things as well. How old are fuel lines? separate filters for each engine I suppose. If both are doing it, it is a common problem. Tank vents OK? What does your Pro say. Most likely leaks would be in recently opened filters, check with a paper napkin its best way to find a small leak you can see it suck right into the paper when you find it. A small suction leak will show up with a lower Tank level and shutting down could introduce an air pocket. it may have been OK if continued to run at that low level without shutting down. Keep results posted, interesting problem.
