poxy things keep allowing lpg to leak by.
wheres the best place to source gm type water hose clips and pliers...?
18mm diameter hose iirc
-
Breakers or GM :-\
The ones on the radiator aux pipe plumbing might be a suitable size...20mm iirc :-\
:y
-
Will it make any odds if there's a significant difference in LPG pressure vs. water pressure? (I don't know the answer to this, btw, or even if the pressures differ .. it's just a thought)
-
my Zavolli set up has the type of clip that requires a crimping tool-got mine from a lpg place on fleebay :y

twin eared crimp on clip used on oxy acet bottle connections?

er, maybe. Thing is, it doesnt seem to matter how tight the jubilees are, the rubber hose retracts, it leaks, but the clip cant adjust until i do it up again, obviously.
if it was spring loaded, the rubber can retract if it wants, the water hose clips hold a constant tension, plus they dont have the almost flat area behind the screw, which is exactly where the water pipe modifications to the vaporisor have leaked in the past, although thaty was aminor thing partly due to using plastic elbows as a get by.
having removed water pipes from hbv's etc there seems to be plenty of grip on the pipes.
But its a good point, is there comparable pressure between water and gas systtems...?
is 1.1 bar of gas pressure relevant to the whole post vap system? :-\

my water pipes are double wall thickness with cord running through it-they dont do what yours are :o

Any good?

they would if they had jubilees on them, trust me.
hence gm use those awkward spring clips like they do. :)

They fly very well though-I took 1 off ages ago and it slip from pliers and shot off-never did find it ???
-
the top ones come in the lpg kit and artent sdo good for the 11?mm injector hose.
but the bigger ones are exactly what i had in mind. Thanks RobG.
but are they suitasble for gas? hmmm.... thoughts please. :)

After that
clip rocket did that-as soon as 1 need doing on a car--I get my mate to do it ;D
-
So anyone know if LPG post vap pressure is comparable to water hose pressure....?
Although.... I could put both jubilees and hose clips on I suppose. :)
-
I doubt the water pressure hits 1 bar, unless the HG has failed...
-
That said, tractor used to blow its cap before its pipes....

Mikalor clamps are brilliant, i use them on my boost pipes :y
-
Some (most) jubilee clips are crap. Some are very good, and wider so can exert more pressure over a larger area. Mikalor are good, I'd say JCS and Norma are better. Get ones that only just fit. Or use non jubilee type hose clips like these:
(http://thumbs4.ebaystatic.com/d/l225/pict/270892981159_1.jpg)
or these:
(http://www.boostcontroller.com/products/sstboltclamp.jpg)
Search ebay for hose clips they will all come up.
-
Yep, proper hose clips are better but still not the perfect solution.
-
slightly off the LPG discussion but i swapped over hose clamps to jubilee clips for my ''y'' pipe on my breather set up..... defo bad idea as i thought it was very tight when i had put it on.... but was loose when i came to clean them next :o
so back to the hose clamps :y
-
you could use these.....

The problem with Jubilee-type clips is that they pull up around the worm, leaving a leak path.
There's a reason why manufacturers don't use them on new cars
But, to answer your question....

Yes 2woody describes it well. It might also be a case of cheap jubilees. The clamp holding the worm is slightly bulbous to the rest of the clamp, so leaves a slight step, and hence a leak path again.
I do remember Markdtm discussing the poor properties of Jubilees, and why car makers don't use them. His words raining in my ears as I fitted the poxy things, with no other options at the time. :(
-
Could it not be the type of join that is wrong
As already said the gm hose clips are superb for water
Perhaps a banjo type connection would be better
Say similar to the 2 fuel pipes to the plenum
-
put some Heldite jointing compound on it, great stuff, seals anything.
