Everything I've read says I need the '99-'04 Corvette fuel filter/regulator after the Walbro inline fuel pump for my 5.3 swap into a '72 Chev. 4WD. The LM7 engine I got already has a pressure regulator and return line on the fuel rail. Do I need anything different? Thaks for the help.

Then you just need to run a return line from there. You won't need the vette regulator, but you will need a filter of some sort.

It makes sense. I expect to run a pre- and post-pump filter. Thanks for the help!
