Q: Is the 1/8 AN840-4 hose nipple pipe thread a 1/8-27 for use with Facet fuel pump 60200?

The AN840-4 has 1/8" NPT and a 1/4" nipple fitting. It can be used on a Facet pump with 1/8-27 pipe thread.

Q: I am confused about the tube i.d. and the thread size on the chart for these AN840 hose nipple piped thread fittings. The hole I need to screw this fitting into is one half inch diameter. Which one of these do I need to order?

The "TUBE I.D." column is in reference to the rubber tube inside dimension to be used on that unit. These units have national pipe thread, which is a tapered thread, and not measured to identify the listed size, but if the hole has NPT threads, and is approx 1/2", then you most likely need a 1/4" NPT threaded unit. The AN840-6D is an aluminum fitting that has 1/4" NPT & would use a 3/8" I.D. rubber hose.
