Also, will my car still run after this install?
And also, will my car still run after fuel feed mod and fuel pump re wire?

when I did my -6 feed I took the factory feed line off completely and ran the new line right where the factory one was. took a little bit of messing around but it works well and doesn't hang down.

But I was having issues of it going lean uptop.
Maybe I still have a fueling issue elsewere?
It has stock fpr and stock rail.

With a rewired 450 your probably over running the factory fpr. Even on my car when when I had a rewired 450 with a Aem rail, -6 feed and a fuel lab fpr I couldn't get my fuel pressure below 60 pounds at idle without doing a -6 return back to the tank and drilling out the siphon tube. Just drilling the siphon tube might of been enough but as long as I was in there I did my own return line also.

What injectors are you running? Were you running the walbro 450 on stock wiring?
DO NOT do a straight rewire on that walbro 450. You need to do a dual voltage reqire or it will over run the stock regulator. The stock regulator and return line with the siphon drilled to 9/64's CAN handle a walbro 450 as long as the rewire is done so that it maintains the stock dual hi/lo voltage function.

I realize that over running the reg causes a rich condition not lean, my point was more or less just the fact that he should probably upgrade the factory reg with a rewired 450 not that it was causing his lean condition.

I have the re wire kit but waiting on my hobbs switch to get delivered from spoolinperf.
I did a fuel pressure test with a old school guage and was at 43 with vaccum on and around 48 off. Also already drilled siphon to 9/64
