What are the thoughts of putting the hydobooster and master cylinder under the floor instead of on the firewall? Would this cause back pressure on the HB return line and cause problems?

Thanks for all the great info! Was going to have to remove the oil pan to avoid a cross beam in the Bronco and move the low point to the rear anyway. Figured while i was in there I would replace the oil pump as well. Guess I'll be doing a lot more in that area too. I really want to tear the engine apart and rebuild it completely but cost and time might prevent that. Anyway, thank you for everything!
got news for you, the oil pump is behind the timing cover. not in the oil pan. mess with it when you redo the whole engine.

Companies who make custom hydroboost unit have ones that go under the floor. Designed for antique or hot rod applications. The return should be no issue since that is fed under pressure from the pump. Once the fluid exits the steering gear or hydroboost it doesn't have near the pressure as the point of use. It's not flowing by gravity feed. As long as you have a separate return for the steering and hydroboost it should be no issue. Might contact a company called Tallon Hydraulics in Michigan. They are hydroboost specialists. https://tallon-hydraulics.business.site/

I have a used powersteering /brake booster tank, came off of a freightliner MT35 van that would have had that engine /inj. pump in it, not sure where you are located, or how much shipping would be but we could check into that if you are interested
I'm located in Colorado. I'm interested!

Yes sir, you are correct. My mistake. I guess that's what I get for trying to pick my brother's brain at 0300 in the morning haha! Got to get behind the timing cover to address that killer dowel pin issue anyway.

We all have those bad moments, especially as we get older like me. Oil pump, KDP, and a group of bolts you want to apply blue Loctite to all are behind the front cover. Of course when you remove it you have to replace the front crank seal.
