For what kind of Car in 2003, for the most part there are differences, some times big differences.

What do you want to know besides it holds fuel??

V70
are there chambers ? it looks to me like there are chambers....how the levels are balanced..... what is inside of the tank ? fuel pump ? what is a fuel sending unit ? where does an end of the vent go ?.....as you see, curious guy

OK so far we are talking about a 2003, V70. Now I need to know is it a Cross country or just a regular FWD wagon or is it the V70R.

im interested to know too, im having ap roblem w/ losing fuel under really hard cornering unless the tank is pretty full.

1994 and 2003 are not even close to being the same. I suggest you start a thread about your problem.

yeah....keep forgetting that

OK close enough but there are two 2003 V70 NA, one is with an engine designation B5244S the other is a B5244S6.

The tank does not have baffles. The tank is stainless steel on the B5244S6(I think). The tank is whats called a saddle tank, it has two sides because of the exhaust. The level sensor on the left side of the car is where the power comes in and the Pump unit and level sensor for the right side of the car connects to the left, so fuel is kept balanced between the two sides. Some have a Fuel pump control module in the tank.

thanks for the info
my car is 'cheating' me by 3-4 u.s.gals @ fillups, so I keep thinking that maybe that fuel is 'hiding' in one of the saddle sides; I get reserve indicator on too soon.

I'd have to check deeper, but I'm pretty sure that can be adjusted With the Vadis Cart at the dealers. They can take away or add to the gauge so it better fits if your are having a problem.

You can go in and actually monitor how much gas is on each side, it's done in liters per side, I think its 40 liters per side.

I had my DIM software upgraded, if this helps; what you're saying is that through Vadis sensors in the tank can be calibrated/set ??

Some cars, can be adjusted to your situation, I'd have to hook your car up to see if thats do able on yours.
