EARL’S AN Fitting AT9894DBHERL; AN to Metric Adapter AN to Metric Adapter Black -06AN Male Straight 14mm x 1.5 female o-ring

Earl's GM metric fuel injection adapters are now available in black. These special metric adapters screw onto the special male tube nuts found on the GM fuel injection fuel tanks. The OEM male tube nuts have an O-ring that seals on the inside of the female metric fittings. Most vehicles use two sizes of these fittings with 16mmx1.5 on the fuel feed line and 14mmx1.5 on the fuel return line. These fittings are ideal for use with Earls UltraPro AN hose and hose ends, since PTFE liner on this hose is impervious to all types of fuels
