Favor to ask - Fuel Temp

Hi Guys ....

My car is currently down again for some Ummm.... testing

seriously

But I have a favor to ask to the guys that use there cars as daily drives when you get to work tomorrow morning can you please feel the temperature of your fuel filter and if possible can you lean under your car and feel the temperature of your tank.

If you have a walbro fuel-pump that will be even better

Thank you guys that assist in this experiment

Fuel filter was rather cold to the touch, it was 26 degrees this morning. The tank was ambiant tempreture.

From previous experience... mine is rather cold after a drive... expect if I sit in traffic, everything in the bay just soaks with heat then.

I just checked now again and the filter is still cold, well cool really. And the tank is slightly above ambiant.

Why what plan were you thinking of?? Heating the fuel before the injectors to aid in the atomisation??

Its not a Jet engine.

So what was the plan??

cooling the fuel works better in a combustion engine

But heating the fuel is better for atomisation.

Bingo

We have a winner

But you will need at least 10C difference from Ambient

Yeah too cold and then you run into trouble again... I've seen systems where the guys cool there fuel lines with NOS, also little water spray thing from the window washer... but I reckon you would have more success by cooling intake air temps.

Phinx sorry to go off topic but when you fitted the intake manifold did you connect the water hose to it, I am supposing you didnt. Did you feel any hastels with cold starts etc?? I always thought that was doff putting hot water through the manifold, which heat the air the intercooler just cooled.

Would be an interesting mod... or you know what you can do, connect that water lines to a fuel type solenoid, on cold start open up the solenoid boom hot water in manifold...
