Brad Clayton Posted April 9, 2012 Share Posted April 9, 2012 Gotta question about adding dye to the fuel system for a oil growing concern. How much dye are you guys adding to the fuel filter housing to make it worth doing? How are you running the engine afterwards, idle, fast idle, driving down the road? How long have you had to wait to see results with a black lite? Thank you for any input. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted April 9, 2012 Share Posted April 9, 2012 Full bottle to the secondary filter housing idle/fast idle 15 minutes This has worked for me for one injector fitting and one HPFP leak test with the oil drained. Quote Link to comment Share on other sites More sharing options...

cbriggs Posted April 11, 2012 Share Posted April 11, 2012 Agreed, full bottle in the secondary. Only time i've done it is valve covers off, engine idling. Found it in about 15 seconds. Shows up immediatly! (leaking injector body) Quote Link to comment Share on other sites More sharing options...
Brad Clayton Posted April 11, 2012 Author Share Posted April 11, 2012 This one ended up being a regen issue. The thing is a "trophy truck" and gets short tripped pretty bad. Quote Link to comment Share on other sites More sharing options...
