Jonn prepared a new fuel tank for installation in our 1974 Triumph Stag, transferring all required components and applying foam padding to designated areas for protection. He then installed a new fuel pump and connected it. Fitted the tank, secured it, and connected all fuel lines and the filler neck. Installed new fuel sender with seal, then refitted the spare wheel, boot floor, and carpet.
He also installed the water pump and housing, initially finger-tight. Used feeler blades to measure the gap between the housing and mating surface, selected an appropriate gasket, then fitted the housing with gasket and torqued to 20Nm. Removed the PAS belt to fit and secure the lower radiator hose, then refitted and adjusted the PAS belt.
Fitted and secured the heater hose. Positioned the inlet manifold to check hose clearance but was unable to continue due to incorrect manifold bolts. Once the correct bolts were available, Jonn applied Wellseal to all inlet manifold gaskets and allowed ten minutes curing time. Fitted the manifold, aligned all holes, and tightened evenly. Connected and secured all associated hoses, replacing two hose clips that failed to tighten.
Performed a vacuum test on the cooling system, which revealed pressure loss. Retightened all jubilee clips and isolated the heater to retest. System still lost vacuum. Inspected radiator bleed and found it loose. Fitted a new fibre washer and tightened it. System held better pressure, so proceeded to fill with new antifreeze, topping up via the bleed screw. Reassembled carburettors and related components.
Removed carburettor pistons, inspected diaphragms, cleaned, and refitted them. Installed air filter and connecting pipes. Switched ignition on to check for leaks; both carburettors were leaking from the float bowls. Removed air filter and hold-down bolts, then removed both float bowls. Found the O-rings on the bungs had hardened. Cleaned the areas and prepared for installation of new O-rings once they arrive.
