I am sure it is 1-1/4 od. but put your dial calp. on it and check. then go from there. If you need 90 deg. pipe and silicone . hose, call race car solutions and they will have everything you need, clamps etc. They are in FL.. and really great to deal with. Don

 

fuel line

OOPS sorry, it has been many years since I ran a Enderly pump, If you need a adapter. to make it into a hose end from a -12 Call JR @ RBS. He has some new ones that go from a -12 to 1-1/4 hose with 2 -6 return ports for something like $36 Don

 

A -16 (1") should be fine for your combo, heck you could probably get away with the -12 (3/4"), why didn't you ask Spud?

 

fuel size

When it comes to the inlet side bigger is better. And when your combo becomes slow to you, you don't have to buy something again. Don

 

The line from the pump to the barrel valve will be the restricting point, then hat & port lines then nozzles. As long as the pump is back filled, I don't think going from a -16 to a -20 is going to do much with his setup.
