Just a hint...

When checking for an "air leak", don't use carb cleaner or other flammable substance.

Do you want a fire? Use water in a spray bottle.

just a thought from a less experienced member.

That's kinda like checking for a leak on the gas line behind your dryer with a bic lighter!

so,there i was checking for an air leak on my brother's F150.
i could hear it,but couldnt pinpoint the source.
i grabbed my carb cleaner,with the little plastic noodle on it.
sprayed here and there and couldnt find anything,moved over to right side of engine and proceeded to spray some more and to my dismay,it lit up.

entire engine compartment was engulfed in flames.i walked around to the driver's seat and revved up the engine to blow out the fire,fortunately it worked.

the vapours made contact with the leaking exhaust manifold,i guess it spurts a little fire on the exhaust stroke.
i have also use water ever since.
it will make engine run rough,and on most occasions the leak will make noise

Or seeing how much gas is in your tank with a Bic.

LOL, reminds me of an episode of '911 Emergency'. Two guys were stealing gasoline from a van. They'd poked a hole in the gas tank with a screwdriver and was filling a pan when one of them decided to see how much gasoline they had. He used his Bic lighter Got both of them, the van and the funeral parlor where the van was parked under a carport. Both survived but were burnt to $hit. There is some justice in the world.
