Fit the fuel pump drip tray
Remove the drip tray (shown circled in the photo at bottom right) from the
Spares
card and
prepare it: drill a hole in right rear corner, which will be the lowest point when the tray is
fitted, and flock the drain fitting into place with 5-minute Araldite and flock.
Put a piece of tape over the inside of the tray and over the fitting and leave to cure.
Fit the fuel drip tray to the engine-driven fuel
pump: remove the fuel pump carefully and
along with the fibre spacer block, leaving the
gasket on the engine block.
Clean the threads of the cap screws
thoroughly and apply a drop of Loctite 262 to
each screw.
Smear some gasket cement on both sides of
the spacer block and then refit the whole
assembly: hold it together with the Allen
head cap screws through a flat washer, the
drip tray, the pump flange, the spacer block
and the gasket and screw into the engine
block and tighten the cap screws firmly.
