Fuel travel time?

[DEFYANT]

DFQ:

How long does it take for the fuel to get from the tank to the engine?

[sweetair]

That depends how hard you press the accelerator down.:banana2:

Not long enough.:D

At idle...Real fast.

At WOT...Really ******ing fast. :D

Ok, I give up. Whats the answer? Dennis:beer:

There has to be some sort of formula for this. The fuel pump pushes the fuel at a certain PSI. The line is a specific distance. With those two numbers, you should be able to find out the time. I don't know either number so I can't help. :) It's probably only a couple of seconds. I know when I changed my fuel filter, it took at least a couple of seconds more than normal to turn over.

On highway hard acceleration WOT from 65 mph to ???? the fuel travels at "Ludicrous Speed". I discovered this on a recent highway trip. Amounts to about a quarter of a tank per hour of fun.

I do not know what kind of fuel pressure system we have. However depending on which of these:

It would make a difference as to the speed/movement of the fuel in the lines.
Area times pressure = force.

Thank for the diagrams, 'Rod, but they are of a "return" style system. The Marauder is "returnless", no lines draining excess to the tank.

Using your diagram, the fuel leaves the tank by an "in-tank" pump, which feeds fuel to a single fuel filter mounted on the inside of the frame, under the rear passenger seat. From there it goes forward to a fuel pressure regulator, and on to the fuel rails and injectors.

No return of unused fuel. When you shut off the car, the fuel system remains under pressure and loading the rails. When you start the car, ignition is programmed to delay a moment to allow the fuel system to pump up to pressure. Upon ignition, the engine will ramp to 1600-2000 RPM to burn off the old fuel left on the rails and injectors since the last start-up, which is where our "vrOOM!" at start-up comes from.

With regards to the initial question...I don't know exactly how long it takes fuel to leave the tank and get to the combustion chamber, because fuel is always present and ready under pressure at the injector. You would have to flush the lines dry, and time the flow on dry lines to learn more.

I suppose this could be done, but first...Is there a reason for this question?

Is there a reason for this question?

Nope. Just one of those dumb things that was running through my head the other day while cruzing "in the zone".

Idle minds.....

Put the car on a hoist, go WOT, and have someone disconnect the feed at the tank...tell us your results :P
