Hello fellas i have searched and tried to find the answer to my question and can not find it... sorry if it already has been covered many times but i could not find the answer.

2006 silverado 4.3 v6 swaped out for a 2005 escalade 6.0

i have swaped everything out already and last thing i need to know is

6.0 returnless fuel system(e85 bla bla)
4.3 has a return line

now my question is...how do i make fuel system work w/ the 4.3 fuel lines?

or should i just switch everything out form the escalade.. fuel system
lines pump assembly ect.?

any ideas would be greatley appreciated


any write up links/pics would be nice PLZ help

OH! and will the 06' V6 rear diff gear be ok or should i switch it out?
