David Brown 990 Fuel System
Back to the wire wheel and the bench grinder to clean up the old parts
DPA pump rebuild
Striiping down the pump, cleaning everything inside and resealing with a sparex kit.
the kit contains all necessary seals, filters and caps to complete the job, I had to buy a 5/16"
allen key to release the drive bush from the front, some big fisted bugar had been in here with a hammer
and given the retaining bolt a lip.
