Certainly can with a decent hand held pipe bending tool, as it is formed / shaped to prevent kinking. With 15mm upwards you need the correct blocks and shapers to form smooth bends.

Pete Lewis Posted August 7, 2018 Report Share Posted August 7, 2018 reminds me when we first introduced robot ?? benders for some long pipe runs , the end of the pipe would fly around as it oriented the bends on 10ft long pipes pre formed to dodge all the chassis components spectacular on preview day most stood too close and ended up with a whack a lot of ducking and shouts...ah the days of H & S we then took on nylon in 78 and all services had blue orange yellow but out in store in open chassis the uv wrecked the nylon and all went to black pipes with the colours imprinted so you could trace the service. pipe ends were a pressed in firtree which led to plastic slivers they got fired down the lines to make air valves leak ................ and we get them now 40 years on with the fuel lines ....there's no escape Pete Link to comment Share on other sites More sharing options...
Adrian Saunders Posted August 7, 2018 Author Report Share Posted August 7, 2018 Can anyone beat £22 for 2.5 m of 5/16” Kunifer? Link to comment Share on other sites More sharing options...
Guest Posted August 8, 2018 Report Share Posted August 8, 2018 Nope, provided it is proper kunifer (90% to 10%) - thought I did well for £25 at the Stoneleigh Show back in February !! Link to comment Share on other sites More sharing options...

Adrian Saunders Posted August 10, 2018 Author Report Share Posted August 10, 2018 CuNi test piece. Spot on. Only required one quarter turn after nipping to seat the olive, and I cannot twist it. Thanks to everyone, problem solved. 1 Link to comment Share on other sites More sharing options...

Adrian Saunders Posted August 12, 2018 Author Report Share Posted August 12, 2018 Guys, job done, can’t thank you enough. Tube fitted tonight, few tweeks to angles and some mat’l removed, ready for final fit tomorrow night and finally, tank and tubes in for good. 1 Link to comment Share on other sites More sharing options...
Colin Lindsay Posted August 13, 2018 Report Share Posted August 13, 2018 That's a lovely piece of pipework - it's going to look good on the car. Glad things have sorted themselves. It's always nice to beat something mechanical that won't play ball. Link to comment Share on other sites More sharing options...

Adrian Saunders Posted August 13, 2018 Author Report Share Posted August 13, 2018 All done with one of these. Link to comment Share on other sites More sharing options...
Guest Posted August 13, 2018 Report Share Posted August 13, 2018 Similar to mine and is perfect for pipe 6mm to 12mm - the fact that you can use it to make any number of bends in any direction makes a DIY job very straight forward. Link to comment Share on other sites More sharing options...
Adrian Saunders Posted August 13, 2018 Author Report Share Posted August 13, 2018 Now then, which nut? The one with the non-threaded section at the end doesn’t work for me, too few threads engaged. But that’s the one that came in the kit. The other, longer one, does, more threads engaged and the same as the one in the fuel pump. Link to comment Share on other sites More sharing options...
Adrian Saunders Posted August 13, 2018 Author Report Share Posted August 13, 2018 If I can get this reproduced, is anyone interested? I can model it in Inventor (3D CAD) and get them made. Link to comment Share on other sites More sharing options...
Pete Lewis Posted August 14, 2018 Report Share Posted August 14, 2018 My box of fittings all the sleeve nuts have aprox 13mm of thread and the end is turned to the relief shown in you left nut The dangers of a full thread is in some applications the nut will bottom out thread bound and not clamp the tube The relief is there to ensure this doesnt happen certailly if used on brake pipework..

Pete I could only engage two threads with the relieved nut so I went with non-relieved. Link to comment Share on other sites More sharing options...
Pete Lewis Posted August 17, 2018 Report Share Posted August 17, 2018 https://rimmerbros.com/Item--i-60176 60176 shows as a relief ended sleeve nut , i would think your problems might start with the pump manufacturer not long standing sleeve nut design just a thought pete Link to comment Share on other sites More sharing options...

I had the same problem with 1/4" olive in my Mk3 Spitfire's fuel tank. The relief on the nut was just too much to engage the threads. Link to comment Share on other sites More sharing options...
Pete Lewis Posted August 19, 2018 Report Share Posted August 19, 2018 so there's some need for both , no idea where you get the full threaded ones from . any clues ??? Link to comment Share on other sites More sharing options...
