under rear seats?

Thanks for explaining this to me. What a great website this is.

If they put it under the car, the driveshaft would hit it when the car raised up from either being on a lift or going over a dip in the road. That could be a bit dangerous.

If your LS's driveshaft is moving up and down when you go over a bump, you need to get your LS checked--the punkin and transmission are both bolted to the chassis.

I'd guess that it goes over instead of under for one of the following reasons:
* there may not be enough room to get a strong enough connection that would still allow for decent fuel flow;
* nobody wants to drop the fuel tank to service the punkin, driveshaft, or parking brake linkage;
* going under may violate safety regulations;
* if it goes under, you have to worry more about low spots.

... i'd rather bottom out on a driveshaft...

Good point. Independent rear suspension, not live axle.

THis is new to me....good place to hide a body or gun (Just kiddin). Well thisl help some with the DIY...just in case my local ford dealership go bye bye thanks to the economy (If it is going to happen)

is that access hole large enough to remove the sending unit/fuel pump? Reason I ask (some of you probably know where I'm going with this) is that even though many cars have this, the access hole isn't always large enough to pull the unit, just room to get to the harness and fuel lines...hence why the stealerships will still remove the tank ( or will at least charge you for that). Personally, on several occasions, with crappy cars and permission, I've just "enlarged" the hole to remove the unit...

When the dealer needed to replace the sending unit for the gas guage, he just worked under the seat. Didn't drop the tank.

BTW, if you smell gas while driving, the dealer or mechanic probably pinched the gasket/seal for the access hatch. My dealer goofed and I smelled gas for a few days until they fixed it.

Maybe on a live axle... not on IRS. Drive shaft is stationary.

What I don't understand is why they saddled it over the drive shaft and not under it, once I see the layout I will understand.

Hope I didn't dig up someone's grandpa with this thread, but I was under the car changing the oil when the real reason for this hit me. (Well, not literally. ) The tank is "saddled" over the driveshaft because there's an obstruction under the driveshaft--the exhaust.:slam

On an IRS car this isn't true. The drive shaft doesn't move with suspension travel like on a solid axle car. One the Mark VIIIs the tank goes under the drive shaft. Plus the Mark doesn't have the rear seat access so you have to drop the tank to drop the drive shaft and change the pump.

Dam I'm tired I didn't notice this was already said or that this was an old thread.
