Hydroboost line question again
Looking to make some hoses for someone else on the Hydroboost and Jeep box. The fittings going into the hydroboost are 6AN into 18 mm O ring fittings right? Not just 6AN to 18mm fittings. The hydroboost uses O ring fittings as do the Jeep box fittings. I know one is 16 mm and the other side is 18mm on both the hydroboost and Jeep box. Also what size is the return port off the hydroboost. The other post which I have been referencing is a little off. Durango Boy posted that the fittings used into the hydroboost are not Oring according to his part numbers. I think they are O rings. Just want to make sure. The other poster is using the Orings it looks like.

I was wrong...the stock GM fittings were O-ring. I checked this morning. The ones I got from Hydratech were not O-ring, so it may not matter, but the stock lines were in fact O-ring.
I changed my parts list by replacing the Russell Performance fittings with Aeroquip fittings that have the O-rings.
They are a bit cheaper too.
New List:
From Pump To Hydro:
90 Degree 6AN to 3/8" - RUS-612180 - $26.50 (Blue/Red)
22" 6AN Braided Hose - RUS-632050 - $16.95
90 Degree 6AN Hose End - RUS-610161 - $15.95 x3 = $47.85
Male 6AN to 18mm O-ring Coupling - AER-FBM2609 - $13.95
From Hydro To Steering Valve:
6AN to 16mm O-ring Coupling - AER-FBM2608 - $13.95
90 Degree 6AN Hose End - See Above.
35" 6AN Braided Hose - See Above.
90 Degree 6AN Hose End - See Above.
6AN to 7/16" Coupling - RUS-697100 - $12.39
Summery :
RUS-612180 x 1
RUS-632050 x 1
RUS-610161 x 3
AER-FBM2609 x 1
AER-FBM2608 x 1
RUS-697100 x 1

I was planning on using the Orings for the hydroboost and the Jeep box also has the same size Oring fittings. I have a list of fittings and lines tha tI have made up for the Jeep box and hydroboost also. Iused some of your list and did some of my own.
