putting a edelbrock 600 cfm carb in place of Nikki....do I need to regulate fuel pressure????

 

Oh my.

You'll need a new fuel pump that is capable of more than 6.5PSI and then regulate it to 6.5.

How will you solve the plenum to seperate runners dilema? The edelbrock likes a plenum manifold. Did you get an RB Holley manifold or something? Or a fabbed adaptor to mate the edelbrock to the Nikki manifold?

How about oil metering into the carb? Gonna use one of the vacuum nipples? I'm going to try the one on that's not pulling vacuum at idle. Then again, I might need to drill into the bowl to mimic how oil flows into an RB prepped Holley. Or premix instead?

 

what is the psi on the oem fuel pump?????


I fabbed an adaptor......don't have the cash for a new manifold...

 

premix ...............

 

will a return line not work??? will it just push to much fuel ????

 

The stock pump isn't enough pressure. I think it's something like 4psi.

 

well if I don't regulate it ???? I just hook uf the returne line

 

get a new fuel pump and pressure regulator, hook up the return line on the regulator and plug the one on the carb.
