Supply your 3/8" threaded water/meth pump from a thin OR thick-walled plastic tank. If you're flowing 70/30 or richer, our package of black braided hose and 6AN elbow fittings is the fuel-grade answer. Or, if you're not so bold and seek to save some hard-earned cash, then opt for our basic version with 90deg Push-to-Connect OR compression fittings. This is the relaxed side that passes lots of volume but at low pressure. All configurations feature a generous 3/8" (9.5mm) internal flow diameter.
Note: Kit comes with grommet and bung to tap any thin-walled reservoir with no internal hand access required. Add any 3/8 fitting to start your setup.
Note2: Right side of above image shows Push-to-Connect fittings and direct tapping of thick wall tank vs. use of grommet in thin-walled tank.
