I'm in the middle of by-passing the pump. I've disconnected the two larger hoses from the pump and joined them together using a plastic joint. Since I'm not removing the pump, I left the hose going to the washer bottle still hooked to the pump, not sure whether I actually have to remove and plug that hose connection at the water bottle? I disconnected the 12v plug at the pump. My next and last step is to remove and plug the other hose at the water bottle, the one that runs back toward the firewall and actually is attached to another hose, next to the oil filter (space is limited).
You are the first to indicate that the pump slides out of it's bracket without first removing the bracket? Hope you are right, much easier than first removing bracket?
Found out that the correct part number for the '99 diesel pump is 0018358664, whereas the gas number is 0018353564. Primary difference is that the three pump ports orientation is different. Assume they can be interchanged but would require several different hoses.
