Hi,when converting a brakes system to hydroboost does anyone have input on whether or not to buy a hose kit or piecemeal together a hose kit. My concern is that I will put out the money for a kit only to have to cut 1 or 2 pressure crimped fittings off a hose because the bend isn't correct then have a 45 put on at a hose shop to make things work.
thanks jim

Hi Jim,
For my '71 Chevelle I bought the Hydroboost lines for a 1983 Delta 88 and I was able to adjust the bends to get everything to work without cutting. If I recall correctly Summit Racing had some thread adapters for metric lines to the steering box but I would need to look at my car to remind myself exactly how I did it.
I also had the Chevelle PS reservoir modified for an additional return as I recall. Regarding the look everything looks like it was made for the car.
I also have a Delta88 and so I had an idea the lines could be reworked before I bought an extra line.
One more thing to consider is there are firewall adapters to clock the HB units differently. That can help with clearance sometimes. I did clock the Chevelle differently but as long as you have enough line length you can make it work. Very likely had I not clocked the HB, differently than the traditional, the Delta parts may have worked with even less effort. I think I added a bend and rotated the end of the line. It wasn't that difficult.

Jim,
I struggled with this also looking at different kits from suppliers but cost and the materials used were deterrents.
Once you have your metric to sae conversion fittings for the hydroboost the lines were fairly simple if you have a local NAPA.
I have a long standing relationship with my local NAPA, they make hydraulic hoses and have all the necessary fitting to makeup and crimp the 2 high pressure hoses required. A long one from PS pump to hydroboost "in" pressure and one short one from hydroboost pressure "out" to steering gear box.
I used (4) 90 deg fittings to connect the both hoses at each end.
To clock the fittings correctly, I "borrowed" some hose & fittings, mocked up both lines on the car marking length and clock position of fitting. Completed hoses fit perfectly with no leaks.
As for return they also supplied 3/8" transmission hose (300psi).
Can't remember total cost but it was over 50% less than an online kit and is better since both ends of hose are crimped. I also like the black hydraulic hose over braided lines. Never been a fan of braided hoses.
