Plumbing for a Dominator

That dominator is probably overkill on that motor, but if it runs and you want to be "period" then go for it. The availability of billet stuff has been relatively recent. As to plumbing, you are probably looking at modern race motors that really need a Dominator. These motors need a lot of fuel. They need a good electric fuel pump supplying more fuel than the motor needs at low speed, so they have a regulator to bleed off the extra fuel through a return line back to tank. At high speed it works well, supplying all the fuel it now needs. I hope I explained that OK.
