be sure to apply some oil to the rubber seal before installing the new one other wise you will experience the same problem

And don't crank it on so tight when you put it on. It takes about 200 psi to blow out that gasket. Put it on just like an oil filter. Contact then just 1/4 turn extra.

Also, be sure to fill the filter with fuel before re-installing. The filter instructions and service manual don't mention this. Maybe it's supposed to be common knowledge, but I didn't know. I eventually took off the newly installed filter after the engine stalled after starting and it was bone dry. After filling it and starting again.....problem fixed.
