A must have OBS uograde
Of all the upgrades I’ve made this one is my favorite. The braking feel is night and day difference, it’s worth every penny. I recommend installing the super duty P/S pump at the same time you do the vacuum pump delete kit. It makes it slot easier to install the P/S pump with the fan shroud removed. The delete kit doesn’t include two 18 gauge wires or splice connectors which you will need to wire the new vacuum pumps. For the price I think the kid should include these.

89 F350 Upgrade
I had the hydro boost brake system installed by my trustee mechanic on a 1989 F350 Dually two wheel drive. I have struggled to get the stock brakes to perform like I wanted even after replacing everything. I’ve drove about a hundred miles with the hydro boost system and it’s exactly what I was hoping it would be. The brake system performs like a 20 year newer vehicle. My mechanic was very impressed and said he was definitely going to install the system in one of his projects. Thank You

Best Brake Upgrade Ever
My OBS is a 521 gasser running on 40’s,I installed the hydro boost and the upgraded Saginaw pump. Install took less than 3 hours. Wish I would have done this years ago. Kit was plug and play, everything lined up and hoses fit perfectly.
