This should be sticky
Originally posted by AndyP View PostA few people have asked me how to use the kit so here's the instructions:-
This is what you get in the kit.
The steel bung goes in the breather pipe on the side of the MAF - Turbo hose.
The large bung goes here (1) and the smaller one goes here (2). Then connect an air line to the valve and pump it up to around 1bar ( 14.5psi ) any leaks will generally show up well before you get to 1bar. Any more pressure and you could risk damaging the MAF - Turbo hose as this does not generally see pressure. If you think you have a small air leak, go round all the joints and spray with soapy water. If in doubt, fit a Mark H mod and replace all the vacuum hose, it's only about £3/m from GSF and if it's original I almost guarantee its knackered.
