He may need to add a regular just before the rail. I would probable remove the vette filter/regulator and put a regulator neat the rail and a return hose from there.

We run the 450 pump to a set of stock truck return style rails with the regulator as part of the rail and have not issues with pressure at the rail.

After researching I'm seeing others have had this same issue with the walbro 450 with a vette fuel system. Some have solved it by enlarging the return but my return is -6 just like my inlet so I don't know where to go from there. I wouldn't mind trying the return style system but that would require buying more fuel line and a different set of fuel rails. I think I'm gonna stick the stock pump back in and if the pressure goes back to normal I'll just run it that way until I can afford to replace the vette piece with an adjustable regulator and filter. That way I can mount that setup next to the tank and not have to buy more fittings or fuel lines. Don't know if I mentioned it but the company I work for recently cut my pay by over $1000 per month so until I find a new job I can't afford to buy anything else so I'm trying to work with stuff I already have right now.
