Now you even clean CSFI injectors

[speedygonzales]

For those with fuel injection, cleaning has always been necessary but difficult. If you have the spider injection system of the 4.3 or 5.7 Vortec. Up till now it's been impossible to do professional on the rail cleaning.

I had the old system of hose connected to pressurized cans of cleaner. You've seen the deal. Hook to fuel rails and disable the fuel pump. But that was only good for normal pressure systems below 40PSI like my LT1 camaro I used to have.

This would not work with the L31 and it's CSFI system. Since it requires 60 PSI.

Well boys the CSFI is not a problem any more. I got and used one of these just last week.

You use shop air to dial in the pressure of the system you are cleaning and it even has it's own pressure gauge to check the system pressure before doing the cleaning.

The cleaner is somewhat hard to find since most auto parts stores don't carry it. At least none of the ones I checked, like Advance, Auto Zone, AutoValue, NAPA, Pepboys or O'Reilly's. You must use a cleaner that will burn. The type of cleaner you pour in the tank will NOT work.

Got some of this from my Snappy:

Called Petrol fuel system cleaner.

Also got some of this from the Honda dealer:

Scroll down to product number 210. That same page also has the same type cleaner from BG.

For those that have tail pipe sniffers in their state. (I don't in Southern VA). This will help you pass emissions tests if you fail even after having done a complete tune up. (Assuming you don't have a dead cat).
