So, I'm doing the coveted EFI to carb conversion on my 88gt guys. The only thing I'm struggling with is how to retain use of the stock fuel lines without cutting them up. Does anyone know how you would route the lines if you're using the stock efi in tank pump with a holley 12-803BP fuel pressure regulator with a return line?

Hi Pete,

I did a carb swap on my 84 mustang and I still use my in tank fuel pump. I ended up using a steel fuel line that with the right nipples, threaded right onto my mallory fuel regulator. I have no problem with fuel to the carb and the return line is steel also. I have it all going into an edlebrock carb so it might be different, but I think that when you get the right nipples to thread into your fuel regulator, you can just use hose clamps to hook them up. Good luck.

I have a pic of my fuel regulator set up but I can't attach them to this post.

Hey Pete, I just used a hacksaw to cut my lines, we have a sending and a return line. What I did is once I cut it I "T" the two lines, put the other end to a Holley fuel pressure regulator. I use rubber hose and slip them on and clamped them. That way if I want to go to EFI again I can just put a disconnect tool on the fitting, and hook it back up to the EFI Fuel rail when I want to. All together I used rubber hose... and works great for me...
