Leaking Petrol warning system Mod-Silicone

Ever drive your 930 after having the CIS or the injectors off only to smell petrol?

Then you have a look and cant see exactly where it was leaking because it has evaporated??

This is my fix to that problem

Wipe a small dab of silicone on outside of every joint where fuel is travelling,

ie: injectors, fuel filter, fuel head..

If petrol is leaking from any of the spots where you have wiped the silicone you can tell instantly,,


Because silicone turns slimey when in contact with petrol and breaks down and it wont dry

So if you get that smell just touch each silicone dab with your finger and the slimy wet one you feel will be the source of the leak

Even if you don't smell petrol you can still check quickly every week or month to see if the silicone is still dry if it is slimy or wet then you have a leak that you didn't know about
