...make sure when you've finished fiddling, make sure the fuel banjo's on ya carbs are tightened up properly!! After fiddling with bits and pieces on how i'm gonna re-route fuel lines, at weekend, i could smell petrol from outside car. looked under bonnet, couldn't see leakage. ran engine and saw petrol pissing out from top of carbs!! Major disaster prevented!! Would not have been nice while driving along to have flames coming from underneath the bonnet, rather than the exhaust!!
