Question Evap bypass

has anyone bypassed the evap system on their blazer? I have my tank out and id like to get rid of anything I don't need, we don't have and smog bylaws here so id like to just run a single vent line and a fuel line to the pump and get rid of all the other junk. Has anyone done this before without any issues?

Re: Evap bypass

Vehicles didn't have evaporative emissions systems before that time so yes, it is easy to do.

Although, the system saves some fuel and seems to keep fuel a little fresher, longer. Plus you cannot buy a truly vented gas cap anymore. They all hold at least a couple pounds pressure.

Re: Evap bypass

Why get rid of something that works? EVAP systems, EGR etc... are all good things if you understand how it works and what they do. IMO, keep the truck the way it was designed.
