I just don't want to buy the wrong size barbed fittings.

See post #11 in this thread for a complete list.
EDIT:
I just realized I said 1/8" FNPT elbow when it should have been Tee. I corrected that.
Use 5/16" tubing for the inlet to the pressure regulator + EFI clamps.
Use 3/16" tubing to connect to the low pressure side of the fuel pump + EFI clamps.
The short length of 3/16" tubing on the bubbler port connects to a 1/4" barbed elbow. The hose needs to be soaked for a few minutes in hot water to make it limber enough for the fit. All low pressure fittings that have a barb can use spring clamps, but any hose attached to the fuel pump needs EFI clamps because it has no barbs.
The straight barb that I put on the fuel rail is 1/4" barb and the hose is also 1/4". All barbed elbows are 1/4". The Tee is also.
Make sure you look at the addendum of the video because I had to change the way some of the tubing is connected because of leaks.
