74-5.7

58psi is the magic number. the corvette fuel filter/regulator is a 58psi unit, the return line will come off the filter regulator. the wix part number is 33737. these can be had with 6AN fittings instead of traditional fuel injection fuel line connectors.

That's what I am using. I think you need another 644123 for the Hemi fuel rail, but double-check that. I have an aftermarket fuel rail, so I don't have that fitting in my fancy spreadsheet.

The fittings I used are:
1x Russell 644113 [5/16"] return port
1x Russell 644123 [3/8"] feed
1x Jegs 555-103121 [3/8"] regulated output

You are correct Alan, that is why most of the gen III restomods run the corvette regulator as the psi requirements for the vett and gen III are basically the same

Apparently Jegs sells it as a kit ?

The kit looks like it will work just fine.

Think "factory connections" from a mass-production standpoint when looking at the corvette filter. They just used push-connect connections to make it quick, no threads.

That's a pretty convenient part, glad I clicked.  Hiding something up under the car, close to the tank, is my goal as well.

what problems were u having with the corvette style filter??

As I understand it, the FiTech can be run with or without a return line.  On my 340, I installed the return line.   I had a pressure gauge in the line for a bit but never saw anything other that zero on the gauge.

I would echo prior comments about using a braided flexible fuel line vs. hard lines.   I used braided stainless steel AN6 throughout and mostly followed the path for the stock fuel lines, but it was very easy to adjust when needed.
