Can anyone let me know how this is done? Is it just a vacuum tube connected to the intake manifold and it sucks it out of the can like a straw?



Thanks,

Total bull s*it snake oil.

They refuse to tell you on the site how it works so it is a total rip off product in my opinion.

Most injection cleaning kits tap into the fuel line, if it doesn't go thru the injector it does nothing. Of course, cleaning injectors by this method is usually a waste of time and money. Dumping a can of Berrymans Chemtool in the fuel tank will accomplish the same result over a longer period, and it works for carbs, too. An injector clogged by deposits is really not a common occurrence. Chemical salesmen lie worse than politicians.

Did you do the leak down test on the fuel pressure?

William Oliveri did pass the time by typing:

Eech.. save your money. At that rate this newsgroup should cost $50 a day. At least this group has more information than some huxter selling instructions.

For fuel injection the can is actually under about 30-40 psi of pressure and the cleaner gets pushed into the rail.

It goes like this:

1) disable or bypass stock fuel pump (connect hoses so the gas just flows back to fool the computer) 2) plug the fuel rail ports 3) screw in a pressurized can of heavy duty injector cleaner/fuel into the rail pressure port. 4) start car and run till it quits 5) put every thing back and run car for a few miles.

The injector cleaner used is not safe for the fuel pump or hoses, that's why you have to feed it directly into the rail.

The remainder of servicing includes replacing the fuel filter and maby cleaning/checking the injectors and replacing O rings if there are leaks.

Adding a bottle of fuel injector cleaner (NOS brand or Valvoline etc) to the fuel tank with a fill-up is about all you need to do. And then only once a year or so. The exception being if you get a tank of crapoline that requires draining and flushing.
