Hydroboost Install question.......

[protour73]

I just picked up a new Hydroboost system for my '73 Camaro. I have been scouring all of the threads on this subject, to reduce the number of potential problems others had, so this will probably be be the first of many posts by me......hopefully not!! LOL

The first couple questions I had were concerning the low pressure return line to the PS pump. In this thread https://lateral-g.net/forums/showthread.php4?t=15052 Scott shows a fuel cell bulkhead fitting installed on the reservoir of his PS pump.

question #1 - fitting is installed ABOVE normal fluid level? At what point is the 'normal fluid level" determined?

question #2 - approximate PS fluid needed for the entire system once the HB is installed and seasoned? PS fluid recommendations? Royal Purple, GM, etc?

question #3 - to replace that brass 90* fitting (low pressure return line to PS pump?) what size is the thread size on the HB unit?

question #4 - I have a brand new Saginaw-style PS pump, will this pump be adequate for the HB system? Have read that the cap needs to be vented, how is this accomplished, just by simply drilling a small diameter hole in the cap? could it potentially leak from this hole?

I hugely appreciate any and all feedback on this.......in advance THANKS

Is this a Hydratech produced system? It sounds like it could be per the description of the brass nipple? If it is, then I feel better about spending time providing tech, if not, well, I'll still help out the Lat-G guys

* The brake assist unit will only exhaust anywhere from one to three tablespoons of fluid "back home to the PS pump reservoir" every time you let off of the brakes (depending upon how deeply you apply the brakes), so the location of this extra return nipple in the reservoir is of no consequence - you can put it anywhere you like. Do note that you MUST run the low pressure return line from the steering gear back to the original LP return nipple on the PS pump reservoir (as this is critical).

* One quart is typically all it takes on a PS system that has already been running. More will be needed on a completely dry all brand new PS pump and steering gear (get two quarts). The Royal Purple Max Ez PS fluid is our recommendation these days (not the trans fluid). http://www.summitracing.com/parts/RPO-01326/?rtype=10

* The thread size is 5/16-24, and you can obtain HBS9101 as an alternate replacement on this page: http://www.hydratechbraking.com/hose...AB01CF20281380

* A stock full size Saginaw P pump is plenty enough to run this system, and stock type replacement caps for these pumps are already vented.

Yes indeed Paul, it is a genuine Hydratech unit. Thanks for checking in and answering my questions!!!

Can those fitting be purchased from you directly? or from the Authorized Sellers like CPP and Summit.

Yes - the fittings can be purchased directly from us on this page by simply clicking the Add to cart button. CPP may have some of the HBS9101 in stock, but I this would likely be greek to Summit Racing.

HBS9101 is the AN6 adapter for use in place of the standard brass low profile return line nipple.

Thanks again Paul........ I will get an order together.

I will post up a thread of the entire install, with some modifications so other can see how easy it is to install this unit and go out and buy one!
