I agree with you Dennis. But I’ll say no sign of failure except loose fit on reinstall. No bulging on test running. (week) I have to get going tomorrow so I did what I did . New engine I hope this winter so new hoses all round. My comment about the stainless pipe being undersized was just a throwaway. Showing my neglect of the obvious. I’ll say I do like spring clamps, when tight and hard to install , over gear clamp , in this application Ab > On Aug 26, 2021, at 8:28 PM, Dennis Haynes <d23haynes57@hotmail.com> wrote: > > For when needed, most of the Vanagon hoses are available through better local parts store channels.

If this hose was disconnected wit the engine out, the disconnect is likely when the hose was damaged. Under pressure there was likely a bulge indicating the likely problem. As for re-designing that pipe to take a larger diameter hose there is not clearance from that tin and you need to consider the heat from the exhaust heating that tin. As another option if using the Van-Café expansion tank the lower fitting could be changed to use a smaller hose. You do need a loop for engine movement. Note this hose is different for 2WD and Syncro. > > The after market hoses do fit poorly. The Van-Café silicone version of this hose is a great upgrade. I find the Van-Café silicone hoses work really well wit the constance tension band clamp hoses and now use them instead for stainless worm gear clamps Van-Café supplies. You have to match them carefully. > > Dennis > > > -----Original Message----- > From: Vanagon Mailing List <vanagon@gerry.vanagon.com> On Behalf Of Alistair Bell > Sent: Thursday, August 26, 2021 10:50 PM > To: vanagon@GERRY.VANAGON.COM > Subject: Re: We try to go on trip and got hosed > > Right Neil, > > If I listened to “the little man on my shoulder” I’d have been much more critical of the hose. > > Lesson learned….yet another one :-) > > Ab > >> On Aug 26, 2021, at 7:46 PM, Neil <musomuso@gmail.com> wrote: >> >> >>> >>> .....
