Fuel Warmer and Fuel magnet?
 

Okay so i have been doing some research and i was just wondering if some of you could clarify HOW a fuel warmer does it. All i see when i see pictures of them is a brass body with an inlet and an outlet.... is there something special that im missing.

And the fuel magnets. I know what they are and how they do it but how can i go about getting them. Are they available @ a hobby warehouse, or home depot?

Before you go throwing money at magnets, I would suggest giving this a read: http://fuelsaving.info/magnets.htm

Thank you for that. How about a fuel warmer. Some i have seen have two probes comming out of them like for an after market adjustable radiator fan switch. Can someone tell me how they work?

I am just wondering because my fuel lines come in @ the back of the motor and are completely hardlined but i dont mind switching them to a softline if a fuel heater actually works.

From what I've read about fuel warming on here and other sites, it depends on the car. The idea is that warm fuel atomizes better which provides a better burn, likely being done in conjunction with a warm air intake. Some of the sites I looked at I would question their highly dramatic results, but the theory probably has a good amount of merit.

For the DIY route I'd say run some good quality line around/near the exhaust manifold to heat it up, just be sure to keep it somewhat easily reversible so you can give it a good A-B-A test and use something that can easily withstand the temps.

So if I took some 3/8" steel fuel line and routed it along the back-side of my exhaust manifold (not too close) and then back to the TB, this would in effect become a "Fuel Warmer"?

Sounds like an experiment to try.

Here's some ideas for you to heat it. Not so volitale as going around the exhaust. I think the temp to shoot for is about 170-190 degrees.

why not just run a "T" off the radiator hose and have your ridged fuel line go through it? it wouldn't ever get above 220F then so I don't think you would get vapor lock or other vapor related problems and wouldn't have to worry about melting anything.

If a fuel heater increases atomization as some claim, I would suggest getting your car smogged to get a sense of the amount of unburnt hydrocarbons produced. Modern engines are generally very efficient at burning all the fuel available, but very inefficient at extracting useful energy. If you are worried about unburnt fuel, a warm air intake should be more likely to increase atomization than a fuel warmer.

Unless you live in an extremely frigid environment, I would place the idea fuel warmers in the junk bin.

Would you not want to cool the air and heat the fuel to make for a more lean burn?

I'd love to believe this. After the CAT we know exhaust is fairly clean. But, I wonder how much fuel actually gets to the CAT. Anyone have any info? Anyone ever have a 5 gas analysis without a CAT?
