Hi bcbasser,

You can also buy the ofna valve [link=http://www.killerhobbies.com/items/nitro-products/nitro-accessories/ofna-fuel-filter-with-primer-pump-ofn10168-detail.htm] here [/link],

I can personally vouch for the CEN Racing Direct Store, it is fast & they are eager to help!
You can aslo try the Bay, if your LHS's are as greedy as mine. ('PM' me if you want a coupla reliable sellers).
