Hydroboost line help please
I'm currently installing a Holley 950 TBI fuel injection, and there is no vacuum outlet for power brakes on the throttle body. No biggie. I've got this Hydroboost unit on the shelf that I've been waiting for the right time to install. Now is the time. I need help on the lines. I've read several times that there are factory lines available over the counter, but I need part numbers. I need two lines:
One a 22" hose with a 3/8 male flare on one end, and a 18mm x 1.5 male, o-ring compression on the other end. This line goes from the power steering pump to the Hydroboost "in" line.
Another hose 35" long with a 16mm x1.5 male, o-ring compression on one end, and I'm not sure what size goes on the other end, but it goes from the Hydroboost "out" line to my 79 power steering assist control vlave unit "in" line.
If someone could help me with part numbers or vehicle models to buy these two lines, I would really appreciate it. It's gotta be cheaper than having the lines built. I have all the part #s to do braided hose, but this is a "while I'm in there" project, and I'm on a budget right now. Maybe I'll install braided hoses later.
Thanks in advance.

Someone posted a diagram with the Summit part numbers to build the lines out of Aeroquip parts. I think it cost me around $150.

There is one part you won't find a number for, as there is only one place to get it in order to properly make your lines. It's the male to male adapter that goes into the valve, and converts the 7/16-24 bung to 6AN, which is what fitting your hose should end up with. You can very easily find a 7/16-24 to male 4AN but not 6AN unless you find an obscure heavy truck or aircraft parts dealer that has one. They are not common for automotive use.
Now, you can use the 7/16-24 to male 4AN fitting, and adapt it to 6AN to match the line, but there is very limited space between the valve and the frame, and if it's not done correctly the fitting on the end of the hose will contact the frame.
However, if you can find a fitting that is 7/16-24, that goes into the valve, that successfully mates with your tubing design, then go for it, just make sure it's 90 degrees.

This is the hard to find fitting. I snapped the pic before I installed my kit from Hydratech in the car.
It's a 7/16" - 24 to male 6AN

there has been a few members here use the factory hoses and take them to the local hydraulic hoses and fitting shop to have them moded to work, I think YellowSB (Chris I think is his name) had his done this way, I think I recall mrvette also had his done this way to, very cheap if I remembe correctly. I tried Hydratech braking back when I installed mine but they would not sell just the line set and would not sell the fittings either. Today they sell everthing you need to build the line set, you may call them and ask if they sell the complete line set to fit.

They will sell the whole kit as a turn key affair. I was the first person they sold it to. It's about $250 plus shipping for their kit. The 7/16-24 adapter is the only piece of that line kit that they will not sell individually, simply because they know without it they stand a better chance of selling the whole kit instead of a $25 fitting.

I have not spent a dime on hoses, and I have switched from '88 vette serp drive/ps pump setup in a total stock '72 vette, then went to the rack ala Steeroids in about '02 , then went to HB brakes ~2 years ago....never spent a dime on lines...all junkyard engineered....used a total of TWO brass compression couplings....one straight off the pump, been waiting for it to fail...but it's been some 6 years now, and not one leak....3/8 union compression...brass with rings just like a plumber would use....same for the output to rack off the HB unit...
Years ago, I DID have custom AIR CONDITIONING HOSES made up locally....but never hydraulic, I could, but these work fine....

I remember I told someone once that they could make it them self or have a shop make the end of the line properly using the end of the stock line, and guess who jumped all over me like it was blasphemy? TT himself. He went on and on about how the proper flaring kit was too expensive for a normal guy to have in his shop despite the fact that I myself have one.
Since then I don't even bother with that anymore. Buy them for $250, or have a hydraulic shop make them for you for cheap.

Comparing they seem close enough, but I seem to recall someone ordering one and it didn't fit. I'll have to order one and test it and play with it. If it's for real then thank god someone out there sells one. It'll make making lines for Hydros a LOT easier.
