hoobby Posted August 15, 2020 Share Posted August 15, 2020 Have fitted some clear braided hose but can see its shape change under vacuum so not going to drive until fixed I think it's 1/2" 12.5 mm hose can someone confirm Quote Link to comment Share on other sites More sharing options...
cam.in.head Posted August 15, 2020 Share Posted August 15, 2020 When I did mine I did use the 3/8" size but looking back it was a bugger to fit so maybee I used a wrong size !. If yours does indeed measure 1/2" then that's probably what it is .no trouble finding it on eBay just make sure it's the proper reinforced vacuum pipe and all will be well.the original vacuum hose on our cars did go hard and brittle even wHen the cars were relatively new .this was the wire reinforced type . 1 Quote Link to comment Share on other sites More sharing options...
Sutty2006 Posted August 15, 2020 Share Posted August 15, 2020 Plus one on reinforced pipe, that’s why the original has a braided band around it to stop it .......sucking itself in...... oooo errr 1 Quote Link to comment Share on other sites More sharing options...
IanMc Posted August 15, 2020 Share Posted August 15, 2020 (edited) That size is correct Graeme. Funny enough, this is another one of those little jobs to do on my car too. Yours did look worse than mine in the photo I saw yesterday - we shall see... Fingers crossed, this helps solve your problem Edited August 15, 2020 by IanMc 1 Quote Link to comment Share on other sites More sharing options...

Did have trouble removing it from the servo heard the air rush back in after 12 hours of sitting so servo and valve are good. Have ordered 1/2" servo hose and clips will go for a drive next weekend Again thanks for the help. 3 Quote Link to comment Share on other sites More sharing options...
cam.in.head Posted August 16, 2020 Share Posted August 16, 2020 If it survived 12 hours then the servo seals are indeed excellent .and as you say the one way valve too . Quote Link to comment Share on other sites More sharing options...
