Re: p0087 'limp mode' while towing
Posted to Technical Discussion Forum on 8/3/2021

No, there is no lift pump from factory. The CP3 has to pull the fuel from the tank through the filter, and on older trucks with higher miles, they just can't keep up with the demand. I have installed aftermarket pumps, Fass and Air Dog are two good brands, on several trucks including my own.
