Fuel temperatures
 

Every restriction creates heat. Regulators, bypass filters, elbows, depending on the brand, even fittings . Has anyone checked fuel temperatures between a running fuel system with a regulated pump and dead-headed regulator vs. a bypass regualtor loop style fuel system? i only run a one gallon cell in my stocker. i would assume most run 5 gallon cells, and if so i would figure a change in fuel tempurature would not be that appearant in that situation?

just so you know the rules state a 3 gal. cell minimum. in a stocker, i never understood why, but that's what the book say's

Maximum, 16 gallons, no minimum.

When I had my fuel cell built the rule book said 3 gal minimum for SS. Stock is different?

Re: Fuel temperatures
 

It was 3 gallons but I looked in my last printed copy under Stock and there was no mention anymore. But under Super Stock, it does mention that a fuel cell is 3 gallon minimum! I think NHRA has a misprint under Stock but I'm not calling!
Rule or no rule, I can go through 1/2-3/4 galloon from pit to pit. I sure wouldn't want to cut it that close using a one gallon cell. I have a 3.5 gallon aluminum and it's an upright.

Ian, go to this link and make a phone call you wont be dissapointed http://product-engr.com/default.html

I've got an old bud that races an Escort and has always had a 1 gallon cell in it.

None of the responses so far pertain to the question????

no answer yet because I doubt anyone has done an actual back to back -- it would take a lot of time and effort. Although, I do have some customers that have "back to backed" competitors' pumps with our comparable pump and have realized a 7 to 9 degree reduction in fuel temp. Having said that, the primary item you should look at.............to decrease fuel temperature in a fuel system, is to decrease the amount of fuel you're "driving" through the system.

Think about this for a minute since you've already listed the obvious restrictions within a given system. If your engine will only consume 50 gph of fuel, why are you killing the system with over 400...........you've got to do something with the excess, either within the pump (let's hope not, but some still use that style pump because a whole 'nother set of issues pop up there) or bypass back to a cell.

Just wandering myself. That's why I posted. Thanks
