A twisted Bundy pipe

Nice afternoon....right!
Put the front end up and decided to once and for all pull the clutch slave and attendant bits.
Had the slave off the engine flange in about oh 20 minutes or so, everything was going along quite swimmingly, I had read the procedure in the Haynes manual many times knowing I would finally pull the darn thing.
Well........... if you look at the Haynes closely under the chapter referring to the clutch specifically page 114 sub section 15 regarding R&R of slave you'll note that one is to grasp firmly the loose cylinder and with an open ended spanner essentially spin the cylinder off the hydraulic fitting until it disconnects.
Well thought I, I'll just go straight to the clutch master cylinder and remove the hard pipe or (Bundy pipe as Haynes calls it)and off well go able to rebuild ,replace and have everything shipshape in no time.I was mistaken. When I put a little torqe on the flanged pressure fitting at the master the pipe just bent right off and broke.
Now for the $64.00 question(s).
Am I dealing with a Whitworth thread on the original part.
Or can I go with just say 4000psi hose all the way back when replacing. Forgot to mention slave not salvageable.
I'll be making a purchase here in the future and would like to try to make things as safe as possible on our resto mod.
Am I going to have to go to an original part or will pressure be an issue.
Sorry all you purists but my wife claims she'll let me rally if SCCA will sign off on the work I've been doing and I know I can run a line much less expensivly if I don't have to order a repro part.
Looks like the leaves will have fallen before we're back on the road.
 
Time was when the correct "Bundyflex" pipe was readily available at least in dealers and independent "foreign auto parts" stores. I don't know if that's still the case. Can't hurt, though, to take the remains to some local parts stores and see if you can't match up the fittings on new Bundyflex. If so, just buy the right (or closest) length, bend to fit, and you're set.

NB: Bending is best done with a proper bending tool, but it can also be done carefully with hand pressure and using suitably stiff objects (hardwood, metal water or drain pipe, etc.) as your "mandrel"!
