1 Pair of cab hoses with an extra extension closest to the cab pump, made so that they should reach down to the cab pump which is mounted in the body hole. Compare with your old hoses if you want an extension or not, or maybe it will be better if you use the other model of hoses. Both types fit, it just depends on which way you want to run the cab hoses. The cab pumps were available in two different designs, some early models have the sockets for the cab hoses at the top of the pump instead of on the side as later models had. Cadillac replaced these pumps with each other in different designs so you can't say for sure which is the right or wrong design.

Tip!

Be careful when fitting the hoses so that there are no sharp bends.
Here's how to get the air out of the system: Install the cab tubes, hoses and cab pump. Remove the level plug that is on the pump, push a hose that fits exactly into the hole. Make sure there is a tight fit between the hose and the hole. Put the hose in a can of automatic transmission oil. Drive the cab up and down, making sure there is always oil in the can. Now the cab pump sucks in the oil it needs and pushes out the air that bubbles up in the can. The oil foams a lot and mixes with air, now wait until the oil is clear and nice it may take a couple of hours. Then you run the cab up and down again, repeat this until the oil is clear and fine without air mixing. It can take a long time, but if you can wait between the cab up and down runs, it's easier and you'll get a good result. When everything seems OK, wait a while and suck up oil so that the level is a couple of cm below the hole, put the level plug back on the pump, which now has the correct level of oil. Note! only run the pump up and down max. 2 times then it has to rest for a while. It's easy to drive too much and burn the cab pump's electric motor. So take it easy and don't stress about this and it will be great.
