Caterpillar 3208 Solutions This sub-forum is hosted by Mike Hohnstein who has been at this kind of thing for 50+ years now, guess I'm addicted. The saga has been all about progressively larger shop space since then. Honestly, never wanted to get into the CAT 3208's that were originally considered to be a throwaway engine but that's all that works in a FC in my world. Same thing with my Ford toter, that came with a NA, too much effort to hang in a 6, so been at it with the CAT V-8 for 20 years now. In reality you can get excellent life out of a CAT 3208 if it's built correctly. Post your questions about the CAT 3208 engines here and Mike will try to help you out.

Default 3208 looses power then dies going uphill

Ok...I got the rig running by bleeding the fuel system. Took her out and she seemed to run fine...then headed up a hill (1000' at about 6%) and she died.
Bummer...in the lane (did not have time to get to the shoulder) but good thing there was a passing lane.

Was able to get her started by bleeding the system...but could not get up the hill (she would run...but not up the hill)

Had her towed to a local shop (we were a ways from my home).

Thoughts on what this could be?

Whatever caused the need for bleeding is still a problem

sucking air into the fuel supply perhaps. Others have had issues with the Racor fuel gauge and the hose developing leaks.


Could be junk in the fuel system. Are the filters clogged?


Did it loose power all at once or over time during your drive?

Is there more than one filter (the racor)?
The racor gauge reads green...but I agree, it seems that air is getting into the system

Cap the racor gauge air line. Could be sucking air from that. Replace the racor filter, along with the o rings and gaskets. You may have not gotten it sealed properly. Change your primary filter, which is after the racor.

Yes mounted on the curb side of the engine. There are 3 filters there. 2 are oil and the single filter, most forward, is the fuel filter.

Add this to your list of suggestions; the throttle body seal could be sucking air.

OP claims $30k spent on a repower, a fresh pump should be in there or OP got handled very roughly with no love at all.
