replacing an os25fx needle valve with os46la valve

hi all i had my needle valve assy break off of my os 25fx motor on my combat plane although it still functions it is annoying to adjust a floating needle valve. so i have an os46la that is not being used would there be any problems with taking and using the 46la needle valve assy it has a nice metal mount that fits the span of two bolts on my plane. the needle valve its self looks the same.

this may sound like a newbie question but does it matter which way the fuel runs threw the needle valve?

If it fits it should work. The OS 25FX is being brought back by OS. You can search for it through Tower Hobbies site. You can probably buy the parts you need to repair your FX through them.
