the mustII rack on truk has always been a little twitchy, nothing really wrong with the steering just a floating sensation going down the road
i did a little research for using the gm saginaw pump with the ford rack and hydroboost
i found that the saginaw pumps flow at 3 gal per min vs the ford pump flow of 2 gpm
a couple of web sites and forums suggested changing the pressure and flow fitting in the gm pump to a lower flow fitting
i ordered the fitting a yr ago and with the new pump install i was able to change out the fitting
wow, does it make a difference. nothing noticeable now, i always noticed a floating sensation before.
the part number is cpfcv-k do a google search. i found mine on ebay, but year one and cpp have the same part as do a lot of vendors.
the fitting installed in the pump.
