Fuel pumps

Will a pump/pickup assembly from a '98 (return style) fit in a '99(returnless) and up tank? I know that it will bolt up, but is there sufficient depth? someone suggested that the '98 style is longer. Does anyone know for sure if there is a difference in the dimensions of the two tanks?

I'm no expert but I have done several fuel pump swaps in various 97-99 Mustangs. I think the tank itself is different. Lines were located at different locations. But the inside of the tank is also different. The baffles are different in the tank. I think the return cars had more baffling to prevent pump cavitation. Where the returnless cars use the bucket for that and there is also mounting points in the tank for the returnless bucket.

Thats not to say something can't be figured out, but just that they are a little more different than you would see at a first glance.

I'm not sure about the GT's but on the 98 Cobra's they switched to the bucket and upgraded to a 190 lph fuel pump. The lid to the bucket may be different between 98 and 99 due to the 98 having a return line.

ok, how about this: will a walbro 255 pump fit on the "bucket" from a '99 and also fit into the tank?

If so, could i then run a return line back into the tank at a different location (such as one of the various vents, etc)?

I have a Walbro 255 in tank that I bought from vortech. Its different from the one that goes on earlier mustangs up to 97. I just looked at my receipt and it says for 98+ years.
The part # is 8F101-260 and it was $125 plus shipping.

I'm not sure about the return line but on mine it runs back into the bucket. I think it needs to go there to keep the bucket full of fuel. Somebody correct me if I'm wrong.

I was told that the fittings have to be welded to the stock lines comming out of the tank.

Hopefully someone knows of an adapter.
