which sending unit?
« on: September 13, 2010, 07:42:53 am »
I'm doing a blazer tank conversion on my SWB and wondering why the blazer unit have 4 outlets instead of the 3? Assuming; 1 supply, 1 return, 1 vent to filler neck...what's the fourth one for? I've had this truck apart for too long...

seriously...I need to start putting a list of things together to get this truck running again.
Before I finish fabbing the tank, I need to know which sending unit I need to use. I dont have a blazer unit, only the 3 outlet form my pickup tank

The 3/8" line is for gas going out to the carb.
      5/16 "    is for gas return to the tank.
      1/4 "      is for a fuel vapor line (breather) oops- this might also be a 5/16" line.
      5/8 "     is for a filler vent hose.

Thanks DN...so I can use either a 4 port or a 3 port unit as long as I provide a fitting on my tank for the 5/8" filler hose vent.
