anyone use one?
i am thinking about it... one like one of these. http://store.summitracing.com/defaul...rchType%3DBoth

or something like this. http://www.designengineering.com/cry..._fuel_bar.html

the reason being is that i feel that my set up is far from the *best* way to have the return routed (did it this way to get it done and over with quickly) but even after i have the return dump into the top of the tank, it is still going to be sent to the botom of the tank and heating up the fuel. i dont see what it would hurt by trying, but just wanted to ask the opinions of others about this topic. here is how i have the return set up right now. (its the one on the left)

 

is that how your sump looks from behind the car ? anyone who comes behind you is not gonna wanna mess with you LOL

 

i dont care about anyone else or what they want to do.

 

ooops... today must be backwards day. it is the one on the right. (the other left. ) not that is matters. point is how close they are together.

 

rxrotary2_7 - is that AN8 feed and AN6 return?

 

be careful going in and out of driveways.....

i know... my drivway is flat. no incline.

nocab, they are -10 and -8

 

You must have very clean fuel, flowing that much through your filter and back. LOL

k

 

i don't think you need a fuel cooler

 

nocab, there are actualy 2 aeromotive filters inline. one 100micron, and one 10micron. no more stock BS.

 

care to share any logic behind this comment?

 

if my logic is correct. moving a fluid a long distance at high speed should cool down the fluid enough. i think they mainly use those fuel coolers for race cars that the fuel cell is 2 inches away from the hot engine

i may be entirely wrong but i'll double check

 

For carbed engines, increases fuel density (same way intercooler works for intake air) and allows more fuel through the same jet or something like that.

 

I wouldn't bother dude.

Unless your making some serious power, and cooling the fuel is required in order to prevent pinging or something, it's probably a waste of money and space.

 

i figured as much, but just thought i would ask because i have not seen any talk of it. the reason i *thought* it may be a good idea is because there is a fuel temp sensor, but was not sure what was actualy compensated when the temps rise. can anyone enlighten me?
thanks to everyone who replied.

 

If my logic is correct, your logic would be incorrect.
I believe moving a fluid a long distance adds heat to the liquid, thus increasing its temperature. The heat would come from friction.

There is no reason why the liquid should lose energy when being moved.

 

i assume it would dissipate heat. same principle as the rows in a radiator...

 

lol, thats the finniest thing I herd all day but you are both right right in some respects. The large diameter lines may cool the fuel down some durring it's journeys because of the lower velocity but it depends on the heating source for the over all temp of the fuel. To make this easy why dont you just take a temp reading of the fuel after a long drive and take it from there? If it does seem to get warm I'd just put the pick up and the return on the opposite ends of the tank. The tank is also a fuel cooler, it has thin walls and a lot of air flow passing buy it. But to be honest I don't think your fuel would get hot unless your fuel pump is pumping 10gpm across the regulator next to your exhaust then back to the tank.

 

the fuel temp sensor is for hot starts

that is what i figured, but the reason i questioned the functionality of the tank now was because of how close the two (delivery and return) ended up. they are only about 2-3 inches from eachother.
i am going to change it latter to have an AN fitting mounted to the top plate of the tank and run a tube that would be welded onto the AN fitting to the other end of the tank...or atleast further forward than it is now.

 

hey heres an idea, why dont you look at you fuel temps, you already have the sensor

mike

 

actualy i dont. i have custom primary and secondary rails. and tossed the old ****.

 

If you have never looked at fuel temps during the summer it might be interesting. I recall 40+ degC after driving with 1/4-1/2 tank, filled tank and it dropped to high 20's low 30's.
