Using Cylinder Compression to Air up tyres?

Where does the fuel injected into the cylinder go?

Nowhere if you unhook the injector. Naturally, if you can't, this type of equipment isn't for you. Works perfectly on my carbureted Ford though.

I would use this in a trail situation, but as soon as possible, deflate and air back up from a compressor. I don't know for sure, but even a slight bit of air fuel mixture can't be good for the rubber. I would be worried about the rubber breaking down after a while....

The only thing else I have to say about Fuel/air in a tyre is about using the "flash method" to seat the bead of tyres.
Using lighter fluid or other fuel to seat the bead is done be many people with little impact to the tyre (if Done right). I would say the lighter fluid would do more harm to a tyre than a weak fuel/air mix.
last time I checked even fuel injected engines have spark plugs, I don't think that you would have to pull the injector to get one to work. although it will, most likely trip the knock sensor.
just my $0.02

HI All,
I had one many years ago I used on my 1964 Wagoneer (first year for this model, bought new). It pumped fresh air and it worked. But it was very slow. A good compressor is a much better solution.

You guys have never checked cylinder compression? Same idea. Unplug the injectors first, or if you like, just pull the fuel pump fuse and crank until it dies. That deals with the fuel problem. Then install the apparatus. I wouldn't take one in place of a good compressor but it makes for an inexpensive, simple, and reliable backup.

In fact since I have an engine compression kit, I might just get a fitting so I can use it with my compressor's air hose
