I stripped the fillter drain screws , apparently
 

My fuel drain valve was leaking to weeks ago so i replaced it. Apprently i striped the threads in on one hole in the bowl, any ideas to fix it or how much it will cost to replace ?

Isn't the drain side mounted on the housing?

Yes sorry. Im used to fords. Thats why i called it a "bowl"

There are 4 screws that hold the drain assembly on. Is that one of them you stripped?

It is now it leasks very slowly

I don't know the cost to replace, but you could try drilling and taping the hole for a machine screw one size larger.
