supply pump

Transfer pump parts are still available individually through Cat. Doing it yourself, you can save a few bucks, but if your pump had a scored piston and sleeve, and you were paying someone to rebuild, you'd be better off, money wise, buying the OR 3008 reman.

 

Here are the part #'s you need. QTY will be listed first. 1- 6j 2419 oring- 3-7e 2464 check valve-1-7w 0134 spring-1-3d 2824 oring-1-6f 6672 oring-1- 3d 2898 oring-1- 5p 2815 oring- 1- 7c 0396 spacer-1-8n 2637 washer, and if your local "CAT" dealer says they're not available, then order them from Whayne Supply in KY and INDIANA. I think maybe your local Cat dealer is either too lazy to look them up, or doesn't know how to. Seen that a whole lot in the last few years.

 

Anything below 25 psi from the transfer pump, and above 125 degrees fuel temp, according to my training, was considered losing horsepower. Looks like you are above that, psi wise. The first thing I would look at, would be your gauge and related system. More than likely, you are running some type of snubber to keep your gauge alive. They get plugged up over a period of time and use. Which results in an inaccurate reading. However, anything between 30 and 40 psi from the transfer would give the old girl all the fuel she needs to darken the sun light out the mirrors. Then the electronic folks might say you need one of them non-smoking patches for her. All the while, you'll be legal in Cali for a few more years. Go figure?
