I'm going back to carb from fuel injection can you give me some info on the best regulator on there? fuel pump is in the tank 65 pis I need to get back to 6.5 psi

Is there a reason you are not using a stock mechanical pump?

New stainless tank pump is in the tank

I guess I should say the new motor dose have a mechanical pump I didn't think it would take the 65 psi that's in the tank pump

I don't know if any regulator will drop it from 65 to the 5 or 6 your carb will want. Fuel injection pumps are a little different animal than one for a carbed engine.

I swapped a 5.0 Ford engine into a Jeep pickup I owned some time ago, the Jeep was fuel injected originally and the new Ford motor had a carb on it. What I did was remove the in tank pump completely and I turned that portion of the tank into just a simple fuel pickup tube. Then I mounted a Holley electric pump (after a filter) into the line and ran it that way.

If your engine has a mechanical pump you could do essentially the same thing and just use the mechanical pump as a stand alone. There may be some regulator out there to do what you want, but I have never heard of it. To do what I did, all you need to do is remove that screw in cover that allows you to remove the pump from the tank, then remove the pump and fabricate a simple pickup tube with a weight on the bottom to keep it submerged at all times. Mine worked well for the 5 years I drove the truck that way.

Don is right...........there is no way a carb regulaor will knock down pressure from 65 to 6.5. You have to disconnect the tank pump and follow what Don said.
