[yote1234]

i want to eliminate the eec canister in my 72 cheyenne during my restoration. i know the fuel cap needs to be changed to a vented one.


my questions are...
1- can i use my original tank,and neck?
2- do i need new single tube sending unit ?
3- do i run only (1) fuel line from tank to carb ? and what size ?
4- will the new vented cap fit my factory 1972 tank?
5-after change,can i eliminate the in cab wall vent line?

thanx in advance... dave
