I am assisting a friend with his truck build, and have a question to run by you gents -
A tale of two trucks! The first truck is a 2003 SilveradoSS with aftermarket valvetrain and Magnusson Radix kit - this truck suffered a vehicle fire (suspect = aftermarket stereo install) and it burned badly, was a total write-off. The second truck is a 2004 Silverado SS, bone stock. The project is to swap the drivetrain from the burned SSS into the stock 2004 truck.
The issue is: the 2004 truck has the "returnless" fuel system; the donor truck has the full-return system, and is in good order. As both trucks will be completely torn apart for this thrash, I am seriously considering swapping the entire 2003 fuel system (tank, evap, lines) over to the 2004 truck, so that it will have a full return *plus* an external fuel filter. I'm pretty sure that this is technically possible and there will be no issues with chassis wiring or PCM tune etc, but I want to hear your feedback as to whether there is any benefit (small or large) to doing this swap. Would doing this swap make the truck easier to tune, or more consistent in tuning? Any other advantages/disadvantages? I am heavily leaning towards doing this swap, is there any reason I shouldn't?!
