Objectives of this task:
In this task the drip tray will be prepared and fitted to the fuel pump and then the fuel lines
will be fitted from the firewall fitting to the fuel pump and then to the carburettor.

5-minute Araldite and flock
Loctite 518 gasket sealant, lock wire

Spares

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.
