Correct, '03s are 48 psi factory. Mine's thirsty so it idles at 68 psi and goes up from there.

What kind of fuel pump or pumps, are you running FrostKing?

I'm hoping to keep both of my 03 fuel pumps at 50 to 58psi. If my setup works, I'll post up the mod on the forum.

I am using an'03 and '04 pump together in my original '03 basket. They are setup as a return style system and no longer use the stock pressure regulator or fuel lines.

Hummm... Did you have problems with it?
Here's my setup. These are both new 03 fuel pumps. This message has been edited. Last edited by: Ghost03hemi, document.write(''+ myTimeZone('Sun, 20 Mar 2011 18:42:17 GMT-0700', '20 March 2011 09:42 PM')+''); 20 March 2011 09:42 PM

I will have another OEM fuel line supplying fuel to the passenger side fuel rail.

I'm waiting on some s/s crimp clamps to come it for the stock plastic fuel pump hoses. Once there here, the assembly will be installed.
