two fuel return lines....OK?

oldbee, i have seen this done and they wrap the the fuel line with the low side(cold) it works but most of them put it to the inlet side when it should be on the return so that you are cooling down more fuel in the tank. trying to cool fuel from lets say 200 degrees to a 150 is not going to happen in six inches of fuel line. so if we cool down the the return and have lets say 160 and then pump it to the carb vapor lock, hot fuel etc would be all reduced. not six inches at a time. had a guy one time put 3/8 tube welded in across the bottom of fuel tank so as he was driving the air would pass through the tubes and help cool the fuel. i don't know if that really worked but a cool little idea.

I assume they recommend the application of the product with the headers not installed on the vehicle. From what I read from the application instructions is that you paint it on the exterior and if you wish to coat the inside that you saturate a no lint cloth and pull it through the header pipe, making sure to keep the cloth saturated enough as to fully coat the interior, followed by a curing time. No thinning required. Just as with any application of painted on products, they make it very clear that the headers have to be clean from any contaminates prior to application.

Sounds like it is only practical off the motor. did they say how long it would last? What is the gain if you do inside and out. Isn't it 90% reduction of radiant heat from just doing the outside? Maybe I read that wrong.

I don't think it applies here but I will share anyway. My car was purchased with an electric fuel pump already installed on a toggle switch. I always shut the pump off about 20 seconds or so before I shut off the engine and many times just allow the engine to stall from the empty carb. She always fires right up when hitting the toggle before I crank her over.

So what happens if you leave (forget) to turn the pump off at the toggle?

Why would I do that? It only powers up with key on anyway, meaning it will shut off when the key is off if I should forget. It just allows me to turn the pump off even with the key on(or engine running).

sounds like a security system.
