Quick-connect adaptor, straight 332/K7784 JCB, genuine

Quick-connect adaptor, straight 332/K7784 is a genuine JCB part for the JCB machines. This is a straight adaptor.

A quick-connect adaptor joins a fuel hose or plastic pipe to a filter, pump or tank connection with a lock that can be connected and released without tools. O-rings inside provide the seal, and locking tabs stop the joint pulling apart under pressure. Straight and angled (elbow) versions let the line be routed without kinks. An adaptor with a broken lock or hardened O-rings leaks fuel or draws in air on the suction side, causing hard starting and loss of power. Plastic adaptors become brittle over time from sunlight and heat.

Fitting

Before disconnecting, clean around the joint and release the lock as the maker intends (by pressing the tabs or pulling the ring), since yanking breaks the tabs. Push the new adaptor onto the end until it clicks and pull back gently to check it has locked. After bleeding, run the engine and check for leaks. When the joint is released, some fuel spills from the line; mop it up with a cloth and keep it off hot parts. Each time the joint is undone, inspect the adaptor's lock and O-rings.
