This is a complete in take fuel pump system for use with carb applications. Still requires a return fuel regulator and is adjustable 20psi and lower. Will support up to 350hp. Has -6 Out port and -6 return port and also a vent.(5/16" barb or taped 1/8" NPT) It uses a "C" ring that is fed through the top and then bolts from bottom or inside.
Includes pump, mounting flange, 2x filters, hardware and detailed instructions. Will not fit in stock vw sending unit hole. You will need to hole-saw your tank with a 2 1/8" hole-saw then drill the 6x bolt holes. its not hard but take your time. I recommend welding a washer for pilot drill bit used on hole-saw to help keep it from walking because vw gas tanks are thin.
