Can anyone tell me what it is, the rubber fuel hose that runs from the nipple on the FPR to the hard line, it is about a foot long or so. I have searched high and low and can find diagrams of it but not an actual size, I'm thinking 5/16" but want to make sure, thanks if anyone can tell me.

 

Honda uses metric hoses. 3.5mm 5.5mm and 7.5mm

#26 the hose?

 

Yes I 'm thinking that is it, although it sucks it doesn't show the FPR, and on the diagram that does it doesn't show the hose.
