ahh a bit late to mention, but I've had trouble twice with pushlock fittings. It may be that they are perfectly reliable when fitted correctly, if so I have made mistakes 2/3 times I have used them...way too low a success rate for me. 1 ps cooler line on the race car (has been OK for years since when I added hose clamps and 1 failure on the turbo oil feed on the tow car, replaced it with braided with proper hose ends
spend up big on real fittings IMHO, even if you need to get the damn things made to length
sorry to hear about it's death, you are catching up with me. leave it in the corner to gather dust for 3 months until the itch returns
