Hi Guys, have not posted for a while as we started the race season so have been traveling a lot. The old Scenicruiser has been running great, even towing the 35-foot trailer, and the smoke problems we reported over the winter cleaned up as soon as we took her for the first long run. With every mile we travel I learn something new, and also how much I still have to learn. This brings me to this post, last weekend we were returning from Indy, with 12,000lb trailer in tow (2 cars and tools inside). On the long climb off I-74 onto the Cincinnati 275 loop I had to down shift early, then pulled the climb in third at about 45-50mph. As we approached the top of the climb, we slowed a little more then suddenly lost power. First thought was a mechanical failure, but the motor was still running, good oil pressure, and temperature normal. I pulled off to the side and did a quick walk round, no obvious problems, and engine was idling smooth. As I pulled away there was a lot of black smoke from the left bank, which cleared once I got the rpm up in second gear. The old girl seemed to be a little sluggish for the rest of the trip, but that may have been me just waiting for something else to go wrong. Drove her again yesterday and everything seems to be ok. Any thoughts on what the problem could have been? I have a 10 hour round trip planned this weekend with a number of long climbs en-route to Bowling Green, so if I have a problem, want to try and address it before we leave.
Cheers,
Dave

Could it be fuel filters or flow which would slow on a long full throttle application? Then idling, the fuel would flow sufficiently to work properly. (You didn't mention if there was any smoke climbing the hill, I'm assuming there was none.) Just the first of many ideas you'll be sure to get here.

Dave,
I second the thought that fuel filters are the most likely cause. I had a similar experience climbing into Cheyne Wyo. once. I had to get down into second gear on a climb I've made before at 50 in third. I swapped fuel filters at the next service plaza and fully regained normal speeds.

My first thought is also fuel filters. Another is the actual fuel level in the tank - are you low on fuel? Third might be a plugged check valve in the return line - that "hidden" one on the bulkhead.
Change out the filters for this trip, then consider installing a Fuel-Pro filter system sometime in the near future.
HTH,

RJ, where can one find the Fuel-Pro filter system?

Check the pick up tube screen in the tank. It might have some grunge. |

If you go to this website,

there is a computer that will answer all your questions on speed rear end ratios and tire diameters.

Thanks for the posts guys, I changed the filters recently, but did pick up some dirty diesel and have been changing filters regularly to clean it out. I also have an inline electric pump that could be part of the problem. Will focus on the fuel system before we leave this week.
