I was going to replace the jubilee clips that were on the silicon hoses, i had a leak and i tightened every jubilee clip on the silicon hoses i could get to, but still couldn't find any leak, no tell tale signs from any of the silicon hoses with jubilee clips on

.
I had to take it to Wheelquick so it could go on the ramps whilst they had a look,they took the under tray off which i never did and found the leak immediately, it turned out to be an original hose with a clip missing

he said how have you managed that

without it blowing off under pressure, one jubilee clip later no leaks, and no charge from Mike at wheelquick

mind you he did ask me to go with him to pick a car up, so fair trade.
