[QUOTE="Kevin Palmer, post: 535489, member: 54263"] Running rich is an indication the Fuel Pressure Regulator is defective. If so, what happens is the vacuum that is attached to the Regulator has no or almost no affect in the regulator. As a result, it allows the fuels to run at full pressure or near full pressure. If you come up with it running lean, then check the elbow that is an issue on several of our Tracs. Pictures are in my library if you need/want them.... [/QUOTE]
