* Barbs and Clamps: Fuel hoses often have barbs (small protrusions) that fit into corresponding slots or inlets on the pump. These should slide on easily but securely. Clamps are then used to secure the hose. The hose must go on the barb in the correct direction. Force should never be needed.
* Size and Shape: Fuel hoses come in various diameters. Make sure the hose diameter matches the inlet/outlet size on the pump. The shape of the connection point (e.g., straight, angled) should also match.
* Identification Marks: Some hoses and pump fittings may have markings indicating the flow direction (e.g., an arrow). Pay close attention to these.
* Fuel Return vs. Supply: Fuel pumps often have two connections: one for the supply line (from the tank) and one for the return line (to the tank). These must be connected correctly. Consult your vehicle's repair manual or the pump's documentation to identify which is which. Incorrect connection can damage the fuel system.
Crucially, if you are unsure, consult your vehicle's repair manual, the pump's installation instructions, or a qualified mechanic. Incorrect fuel line connections can lead to engine damage or fire. Don't guess!
