Hello , I have searched and found several posts on the fuel problemwith the dual tanks on the F150s. I have a"92" f150 supercab 6ft bed, custom,have owned since new, new motor, new tran. Have had it in for all the recalls. the dealer put the inline check valve several years ago, but i am haveing problems with the front tank over filling, I pulled the bed, since i am going to relace all the cracked fuel lines , I figured it would be easier to get at rather than drop the tanks, I am having a problem getting the inline check valve,since it was a 'fix' the parts dept doesnt know what it is. i took a valve to them, and showed them pictures of it installed on the vehicle. does any one know the Part # for the check valve? also there is one in the fuel pump which they do have a part # for that part, which i was all so going to replace since i was pulling the pump to replace the fuel sending unit. it the check valve in the pump an easy fix, have not pulled the pump untill i get ready to do the job. Thanks for the help. I am new to this site, but from what i have see, it is a wealth of info

They know that there was a recall on this model, which was done ,but have know idea what the parts are suppose replace the check valve. does any one know what the FoMoCo part # is? thanks for your help
