What is the fuel capacity of a 90 LX?

[sunil6784]

My convertible holds 15.4 Gallons and typically goes for about 300 miles on a tank of gas.

Wow ! I usually get about 230, driving 60% city.

I got ALMOST go red line out of gas when i got lost last night then was finally able to fill up and I put 12.6 gallons in. I have a 93 LX

Most I've ever been able to put in 87 lx was 12.9 when you could actually hear the fuel cutting out when flooring it it was so low. My buddy can put 15.1 in his 91 lx however.

Have you tried a tune up? That sounds pretty low.

If the engine vacuum sucked up your tank or the baffles broke loose or if you put in an oversized fuel pump or if your fill pipe it too long or if your vent is not working or if you're filling it on a hill, it holds about 12.9 gal. If it's a 'normal' tank, it holds 15.4.

Huh?

Not funny, huh?

I just was not sure what you were getting at.

Last time I checked, engine vac is not applied to the tank (the vent goes to the Charcoal cannister and the purge-solenoid vents the excess fumes. But it certainly is not manifold vacuum).

Baffles being broken dont change the tank volume - they are still in there.

Gas stations are on flat ground..........

I guess I was not sure what you meant.

Well, it just sounds strange to me that so many people have a fuel tank with the exact same outside dimensions and yet the amount of fuel that fits inside the tank varies so much. Last I remember from my geometry class, the volume of an object can be pretty much determined by its outside measurements. As for my comments...
I've seen a tank collapsed when the vent failed and engine vacuum 'emptied' it (though not on a late model Mustang...
Those baffles won't change the interior volume of the tank, but they can prevent filling up that tall hump on the pass. side where the pump is mounted.
Like wise if the fill pipe is improperly installed, it can limit incoming fuel.
And you're correct, most gas stations aren't on a hill, but then again there's got to be SOME reason for the differences in volume, right?
BTW... I don't park my Mustangs on any sort of uneven ground anymore. Both my 90 and 93 refused to start due to lack of fuel even with over 3 gal. in each tank. Reason... the drivers side was lower than the pass. side. Like a NExTel stocker on a steep banked track, all the fuel ran away from the pump.
