+I am putting in A Hurst Line Lock into our 70 RR. I got all the fittings I thought I needed at the local Carzone store. Pulled the brake lines off the brass block with the shuttle valve thingie in it. I got all 3/16" fittings as that is the line size. However, the line end that goes into the brass block is a 3/16" line but the threads are for a 1/4" line, maybe because the block is brass. So, can I use a 1/4" tee in this situation or will there not be enough flare seating? Otherwise, I am going to have to cut the ends off my nice stainless steel brake lines and put on 3/16" fittings. Otherwise, I can keep the stainless steel lines intact and make up new lines using regular brake line material I suppose.
If I make new brake lines can I just go straight to the Hurst line lock as it has three outlets, eliminating the tee in the installation diagram? What about eliminating this brass block, just put in a union for the rear brake line, which will probably also require cutting the ends to get the right size tube nut to use with a standard union.
Has anyone used the universal installation kit Hurst sells on a Mopar?
I have no problem removing the brass block; less useless weight at the drag strip as it is not a proportioning valve. I think my double flaring tool can survive a couple of flares on stainless. If I use the line lock as a tee it makes more sense to eliminate the brass block at that point.
Hope this makes a modicum of sense.
Best regards, Dave

I'm about to do something similar to my '64 Savoy, but also switching to a double MC, and using a Hurst "Roll Control" (Line-Loc). My car has a similar block, actually a Tee: R/F, L/F & Rear brakes, no low-fluid light like yours. So: 3/16 lines I have use 3/8-24 male fittings. My Hurst LL has 1/8 NPT female threads. My '69 drum dual-MC has a 5/16-? & a 7/16-20 port. I figure MC Ft to the LL, tee the ft brakes there. Rear line will run from MC to an adjustable proportioning valve, then maybe to the old Tee with ft brake ports blocked; depends on whether I can package the prop valve down on the frame rail and still adjust it. I think I can get the LL & PV both down on the frame rail and avoid having to replace the lines to R/F, L/F, and rear brakes. I found adapters in the Speedway (Lincoln, NE) catalog for everything but the 5/16 MC to 3/8-24, but I think I can use a 5/16 fitting & fab that line. Hope this helps. Hopefully I'm not missing something, seems simple enough.

For one it looks all wrong, just my Anti seize does the same thing without the danger of the tape coming loose into your brake system. I bet the tape has turned yellow, that's the fluild wicking out.

"What" looks all wrong ??? Mine's been plumbed like that for 30 years and works like a charm.
As for the teflon tape ... you guys fight it out. Personally I never use it on a flare fitting.

The tape looks all wrong, nothing wrong with the plumbing, I said that looks good, not the tape. I work with flared fittings for a living, tape is all wrong when used with flared fittings.

I am planning on using the washer fluid switch as the button as the supplied button does not work on a pistol grip shifter.
Its pretty hard to see the 'tree with washer fluid spraying all over the windshield !!!
