On car fuel injector cleaning 700 1991

posted by  someone claiming to be ibs740 on  Tue Jul 25 03:04 CST 2006 [RELATED]

Hi,

Where do I find the inertia switch on the fuel pump? I assume this is the roll over safety switch? I am making an on car cleaner (a welded aluminum can essentially).
I'm going to use the commercial FI cleaner OTC's Pro Inject-R Kleen fluid. It would seem that the FI cleaner acts as a gas replacement in order to run the engine. I pulled fuel rail fittings from the wreckers to make a setup.
Anyone do this before?


Below is the excerpt from the Brick FAQ.

We then tripped the inertia switch on the fuel pump to shut off fuel flow and connected one end of the 'water filter' to the schraeder valve on the fuel rail. The other end of the 'water filter' was connected to a simple air compressor regulator which we regulated to around 35 psi and then turned on the air. We started the car and ran the straight fuel injector cleaner through the injectors. Apparently, this is in essence the same way garages and dealerships use to clean the injectors while on the car (using perhaps slightly less kludged equipment). Although it doesn't account for backflushing or screen replacement, it did make an excellent difference in the idling and off-idle performance of my car. Not so much in power but in smoothness. All done with probably $15 worth of hardware (providing you already have an air compressor).
