My 40222 Facet fuel pump outlet port is a 1/8" NPT female that leads to the International fuel filter housing header...does anyone know what the NPT size is of that female fuel inlet port located on the filter housing? I have it circled in the pic. I wanted to get a brass fitting with a barbed end to make sure I'm not sucking in air at the hose connections. Thx in advance...

 

I'm 90% sure it's also a 1/8 npt.

 

I know mine is definitely larger than 1/8", because I just replaced that part a few months ago and it was too big to fit into the Facet pump. They didn't have barbed ends here on the island and had to go with what they had. Can't remember the exact size and didn't want to go through the hassle of taking it off, then taking it someplace to be sized and then order online. But in order to be positive....

 

I was going to say 1/8 as well, but if not try 1/4. If you can, buy a few sizes and ask if you can return the ones you don’t need as your not sure of your size
