Just got my fd and it is amazing! i did notice however that the car seems to run very well on a full tank. the car is completely stock and has almost 60k on it.

 

so what does it feel like running less than a full tank?

 

sluggish, not as much power seems to be "slower". it seems to be this way after it gets close to 1/2 tank. I dont run it much lower than 1/2 but it is a noticeable difference

 

I know the feeling. my FD was the exact same way!

 

Then again it could be b/c i drove some fat girl to the gas station.....

 

yeah fd's are wierd like that. i took mine to a body shop yesterday on like a 1/16 tank of gas..(didnt have time to fill up) and it ran wierd. but considering the cold weather, it sorta made sense

 

It should run the same, but I would suggest keeping 1/4 tank as the minimum just to be sure it doesn't fuel starve under boost. If your car runs different with low fuel you need to investigate inside the tank, the stock pump sock or the tank itself needs to be cleaned, at a minimum plan on replacing the fuel pump sock when you open the tank.

 

If you are going to be keeping your car at the body shop for a long periosd of time, you are going to want to fill the gas tank before leaving it there. Over time, condensation can build up, leaving what little gas you do have to mix with water. Happened to me last year...

 

I would check your gas tank for some sediment or any debris it might have built up over the years.

If you can actually "feel" a significant difference in power and response just by filling your tank, i would be concerned and have your gas tank checked immediately.

 

+1 on what he just posted.

 

with low fuel level and under hard acceleration I would guess that some of the fuel will slosh away from the pick up and you might run into a lean condition and burn up the pump. I know thats the case with my walbro pump. Its a good idea not to take the fuel level past 1/8th tank if you still plan on hard accel.

 

When was the last time you changed your fuel filter located next to the gas tank? Sounds like a pressure problem, could be partially clogged. A full tank has more pressure, thus more fuel flow?

And for MadzaDude7, that was funny, how'ed you get that fat chick in your FD? Like what the Navy says, "its not the size of the ship, but the motion of the ocean"
I won't go drifting with that extra ballast up front.

 

I was warned that you shouldn't run the car past a 1/4 of a tank due to the fact that if you take a sharp turn to quickly and powering out of that turn its possible to blow a seal or damage the engine. But I was told this after I installed a Walbro pump on the car. Also Notveryhappyjack, 1qwik7 and Hawaiianredmako raise a good point. Correct me if I'm wrong though. Hope you figure out whats up, good luck

 

If I am storing my car should the tank be above half or is at half ok? I start it up once a week...

 

not true, 94 octane gas will prevent this from happening

 

I'm afraid octane rating has little to do with that. Put in the additive.

As for the original question, change your fuel filter ASAP. I went thru this recently and because the fuel filter was clogging, just the extra weight of a full tank was enough to improve fuel pressure and driveability. Also pull the fuel pump and look to see if the tank needs drained and cleaned. I'm serious - you could blow your engine driving around with insufficient fuel pressure.

Ive never havent filled the tank yet, im too much of a tight ***

 

I would Def. look at that quickly!!! Check the fuel filter......and fuel pump ASAP!! It's not worth blowing the engine!!!! Good Luck

 

I had a problem with performance with less than a 1/3 of a tank. Turned out to be a failing fuel pump.

 

Suggestion: Fuel Stabilizer,such as Sta-Bil.That way the fuel doesn't "go bad".It's recommended If you are Storing the car..anyhow,Your Problem sounds like a bad Fuel sock.Also you should be looking into Running a better Fuel Pump set-up.If you are Running around on Low Fuel,all it takes is a Little Burp of the throttle,to to get the Engine to run lean.(due to Fuel sloshing in the tank)..that Ultimately Ends up as a Blown engine.

 

i know how that feels.. i drove my cousins and her fat friend somewhere long ago and i mean i hit it and i felt no power and it was sluggish.. once they steped out i tried again and it felt so more power.... and my other cousins been bugging me to give him a ride and iv been making excuses because he is a little over 300 pounds and i am scared of him braking something inside the car..

o and also if its the gas sloshing around cheak out the GB that they are having (link in my sig)

 

Did you put one in the hatch or do you have a back seat? I've been in the back hatch area (6' 180 lbs) with my 6'9" 245 lbs brother driving (fits barely with no sunroof) and my 6'2" 205 lbs other brother in the passenger seat. Acceleration was ok but the turns had me rolling all over the place .

 

no they both sat on each others laps in the pass seat

 

should run the same

 

o well it did, i remeber i said wow i dont even feel that much power.. and they just looked at me.. and i laughed
