Hydroboost Conversion

[IDIBRONCO]

I know that you can just look up a vacuum pump for, say a 2000 F350 with a diesel. That's the one that you'll need.

Great, thank you for the info!

I left the old mechanical vacuum pump in place when i went to hydroboost. Didn't seem to bother it any.

 

[jwsfarrier]

Cool, thats exactly what I was thinking of doing. Thanks!

i simply deleted it

That does clean things up a bit. Stupid question but were you able to retain the original belt?

 

[Lumberjackchuck]

i simply deleted it

Is that a serpentine belt that’s just a little shorter to bypass the vac pump?

If so, where did you get it?

 

[IDIoit]

stock belt w/ vacuum pump

So the tensioner took up the slack from deleting the vac pump?

I just installed hydroboost on my 1992 E-350 along with converting the rear brakes to disc. I used a 1998 E-450 hydrobooster and built my own high pressure lines with a kit from Summit. It was a pain finding all the proper fittings but basically just converted everything to AN fittings as those are easy to work with. I didn't put in a remote reservoir and did install a cooler and filter and the OEM Saginaw pump put out plenty enough pressure it seems. Everything seems to be working great so far.

Did you delete the OEM proportioning valve since all 4 wheels are disk?

Edelman: 6014r, 71415,71416 & any reman hydroboost unit from rock auto

Then just modify the pedal as outlined in my tech article

I ordered the 71415 hose from Rockauto and it doesn't appear to have the right diameter end to fit into the STP56RM Motorcraft power steering pump (which does have the same fitting as the original pump). The hose fitting is a bit too narrow where the O-ring should seat but the threads are correct.

Wonder if the Edelmann pump has a different fitting than the Motorcraft version.

It seems that Edelmann hose part 71442 would be the correct hose to go from the pump to the booster if using the dual return Motorcraft pump found on a 96 Ford Super Duty.

The 71416 however did fit perfectly from the steering gear box to the hydrobooster.

Update: Yes Edelman part 71442 is the correct hose if you are using the Motorcraft dual return power steering pump (such as STP56RM) rather than the Edelman pump referenced by Hacked89.
