4150-Style Dual Fuel Inlet
More from my cleanup efforts in my garage....
Here's a dual fuel inlet for a Holley-style 4150 carb. It has the port for a fuel pressure line as shown. It came with a carb I got and I didn't use it. It seems to be the Russell Performance #641150 that Summit sells for $72.
I'm in the Detroit area. $35 plus shipping.
