reserve gas tank?

[TeamRedLine23]

is there a reserve gas tank in the z32? when the low gas light comes on and when I fill it up it only fits around 12-13 gallons. one time I kept pumping the gas gun at hte gas station and it over flowed at 14 gallons. I have a 1991 twin turbo. thanks

I do know the z31 has a reserve. You place $10.00 in tank when the reserve light is on an nothing. I usually have to place $25.00+ in the tank of the z31 to even start to register

yea I was wondering the same thing becuase I had 1 bar showing on my gas tank (I have digital dash) and I put in 25 bucks and the damn thing overflowed...

i dont think there is a reserve gas tank on the Z32. i know that when the gas light comes on, you have 3-4 gallons left in the tank. personally, i have never seen the light come on in my Z and i have put 13 gallons in it before (i usually put 11-12 gallons in, i am paranoid and always fill up at the 1/4 mark).

medic... dude... could you maybe shrink your sig 'z' pic down a little... that thing is massive

[k3smostwanted]

yeah medic...shrink that thing down.

in a sense all cars have a reserve. it is the gas that is 'reserved' after the fuel gauge says Empty or your gas light comes on. that is your reserve. for most cars it is a few gallons. do Z's or any other cars have a reserve like motorcycles and such, usually no.

This is kinda related, but what was wierd to me, is that my Z used to perform and feel the best when there was 3/4 to a full tank of gas in the car... I just assumed that it was becuase of the extra weight by the rear wheels... I was expecting a better performance or something when I was lower on gas becuase of the weight factor but yea... someone mind explaining htat to me???

in-tank fuel pump's are more efficient with more gas in the tank?...

the more gas in the tank, the more pressure can be built inside the fuel system.

actually, the fuel pressure regulator mantains a constant 43.4 psi, even in the fuel tank. but good guess k3.

Pfft! Just buy a 5 gallon fuel cell and you will always know when you are about to run out of fuel exactly!

umm....the regulator cannot make pressure appear. it stops pressure from going over a designated mark.

im telling you...fluid is heavier than air, therefore the more gas in the tank the more pressure at the bottom of the tank making it easier for the Pump to move the fuel through the line.

kinda like when you're ears pop the deeper you go in water. pressure is causing you're ears to pop...with enough pressure it will collapse your body. air cannot create this kind of pressure.

just thinking logically here...

The car performs better because of the added wieght over the rear tires. The weight split on the Z32 is a bit on the front heavy side, I think its close to 60/40 (not sure exactly). But with the fuel in the tank you can do the math, 17gal weighs about 181 pounds, thats water weight, so fuel you can venture to say would weigh about 170lb or so.
thats bit of wieght to have directly over the rear wheels.

I dont think it willo improve your 1/4mile time but it may improve you 60ft times and your track performance if you can deal with the added weight. But some cars actually are "faster" feeling with a fuel tank of gas, but in actuallity they are slower. I can say that a NA AT Z32 is faster in the 1/8th mile with less than a 1/4tank than with a full tank. But this my own experiance.

[FYI]I haven't weighed my Z personally but a Car and Driver article listed the TT as a 55/45 split.[/FYI]

Sorry Delerious - Was experimenting last night - Will try to fix But you got to admit the Z RULES and deserves a little show off now and then - lol

Poosting again - How is this - no Z emblem
