difrangia Posted February 20, 2015 Report Share Posted February 20, 2015 Anyone have an interchange flex hose part number for the clutch slave Cylinder? I've found one that is five inches longer (17" compared to the 12" original). Won't need for a bit but starting the search early. Steve 1 Quote Link to comment
DanielC Posted February 21, 2015 Report Share Posted February 21, 2015 A 521 uses a USA sized 3/8-24 flare nut on the 3/16 brake lines, and clutch hydraulics. I would think a 320 is even closer to its British measurement roots. 1 Quote Link to comment
Stoffregen Motorsports Posted February 22, 2015 Report Share Posted February 22, 2015 I've used 50's era Chevy truck brake lines on the 320's before. They even have the bulkhead on the one end. I don't remember if the 320 clutch hose has that bulkhead fitting on it though. 1 Quote Link to comment
zed1 Posted February 22, 2015 Report Share Posted February 22, 2015 My search for the hose for the 520 turned up no off the shelf part. I had one custom made using my old one as a sample. Keith 1 Quote Link to comment
difrangia Posted February 23, 2015 Author Report Share Posted February 23, 2015 Keith, That's my backup plan if I can't nail down a dimensional replacement or interchange. RockAuto lists a hose for the 520 for $10. Cheap enuf if it'll interchange. I'll get some photos of my old hose and post. I know it's 12" long, has 3/8-24 male fitting with copper washer for the cylinder end and on the top end it has female 3/8-24 flare internal thread and 5/8-18 outside thread for securing in the bracket on the frame beside the starter.

Stoffregen Motorsports Posted February 23, 2015 Report Share Posted February 23, 2015 That's exactly what I had bought many years ago, and it was a Chevy application. Same length, same threads including the 5/8 bulkhead. I don't remember the exact application, it was so many years ago. Also I searched Rockauto yesterday and came up with nothing. 1 Quote Link to comment
Charlie69 Posted February 23, 2015 Report Share Posted February 23, 2015 In the past I have taken obsolete brake hoses to a Hydraulic Hose store and had them make em.

difrangia Posted March 8, 2015 Author Report Share Posted March 8, 2015 Got a decent photo of the old clutch hose from the 320 today. Big end is 5/8-18 outside thread and 3/8-24 flare fitting internal thread. Small end is 3/8-24 thread with a copper washer that seals against the slave cylinder forward edge. The hose length is 12" If anyone has a used or new hose from the 520 pickup in their stash and could check and see if these dimensions look to be the same, I'd appreciate a heads-up. I can order a 520 hose from RockAuto. Thanks Steve 1 Quote Link to comment
datsunrides Posted March 8, 2015 Report Share Posted March 8, 2015 520 hose does not have the bulkhead but should work. You just need to get a retainer clip to hold it in the hole. 1 Quote Link to comment

I wouldn't have bought them if they weren't. I didn't have an application in mind when I went in to buy them. I brought a stock one in and the counter guy picked one out of the book by looking at the pictures. 1 Quote Link to comment

I've only been to one local parts store and they came up with this one that has correct ends but is 5" longer. It would work but there is probably a closer one out there. Still looking. Here's the one I found so far. I've forgotten but I believe it is Bendix brand. 1 Quote Link to comment

hosestop@msn.com Posted March 13, 2015 Report Share Posted March 13, 2015 I stock 5/8 bulkhead 3/8 inv. fitting can make NOS 20.$ or stainless hose for aa faster clutch pedal , that brake hose is early Chevy if you want it from Napa a little long , If you were going to Datsun swap I could make it and meet you out there or mail it again if you need it I can make it . 2 Quote Link to comment
Stoffregen Motorsports Posted March 17, 2015 Report Share Posted March 17, 2015 I knew it was early Chevy. I just couldn't find any paperwork to prove it. $20 for a custom hose is quite reasonable. Are the hose ends plated or raw steel? 1 Quote Link to comment

Charlie69 Posted March 19, 2015 Report Share Posted March 19, 2015 I find it is easier and quicker to have a hard to find hose made by someone like hosestop than to try to locate new old stock Quote Link to comment
Stoffregen Motorsports Posted March 19, 2015 Report Share Posted March 19, 2015 I have learned to use Aeroquip hose and reusable ends for the trail rigs. They are easy to repair if need be. I also heat shrink the blue Aeroquip hose for added protection and that OEM look. I do love the look of a custom hose though. It's attention to detail that separates the professional builds from the rest. 1 Quote Link to comment
difrangia Posted March 27, 2015 Author Report Share Posted March 27, 2015 Here is the hose that Brad at: hosestop@msn.commade me from the dimensions and photos in this thread. A perfect match delivered in my mailbox for just over $20. I'm 'Small Town' and we don't have a good affordable local hose maker, so I'll be calling on these guys again. Thanks, Brad. 2 Quote Link to comment
