NO NO No.....
Please don't use Jubilee clips (I'm certain Steptoe knows about this) Mr Joe Public is very susceptible to suggestion and any old Jubilee clip just will not do. For fuel lines you must use the correct type of fuel pipe clamp, these are able to clamp through almost 360 degrees rather than just squeeze the pipe tightly and unevenly like the Jubliee clip...a fine product but not intended for this particular type of application!
