Fuel Heaters

Do they work? Or just a 'Net myth?

Run down on the theory. Your fuel line to your injectors or carb are rerouted to a holding canister that is heated by your engine coolant. The now warmed fuel can be atomized into a finer spray by your fuel injectors resulting in a more efficient burn.

Thanks

I'm going with net myth. Properly design modern FI systems should atomize the fuel over a wide range of temperatures... But, it may be like acetone, where it can clean out older injectors, or in this case, help injectors that are in poor shape.

The Hydrogen-boost guy uses them in his solution :

Other people have gotten mixed results. My mechanic doesn't want to mess with them because he doesn't want to cut the fuel line. They are common in (older?) Diesels for pre-heating the thick diesel fuel. In one Mercedes Benz, my mechanic told me that the fuel line runs *through* the coolant reservoir.

I also agree that the older the car, chances are, the better the results.

The one you are showing appears to be the best manufactured.

What kind of testing are you going to do? Can it be controlled? (Would be tough, I imagine, if you have to do a lot of wrenching to go from "A" to "B".)

I will probably rely heavily on my current figures for a baseline. As for the difficulty of going from "A" to "B", the heater is supposed to have a type of quick dis-connect fittings. It would just be a matter of the pressurized fuel in the line leaking out when the connection is loosened.

Are those the "bypass valves" I saw before? I keep trying to find a picture on the net of the fog device with the bypass valves, but they seem to have vanished.

Thanks, that report matches with what I originally thought, FI vehicles vaporize fuel to such a high degree that heating it is pointless. But I figured it was worth a shot.
