Vettech:
I think this subject has been minced over a few times, and I've  never followed thru with fixing them, but now I've four (4) seats to contend with.... time to bite the bullet.

First port of call will be a cycle shop. Stay tuned.

MY081:
TUBES ?????????

MY081:
Bicycle brake cables also make great emergency Bonnet pulls just hang it state down. Ray

Vettech:
Yes - Tubes
When I can walk again and for that matter "drive" I'll ring a Joe I know will know.

These pumps are very simple, electric motor  turning a cam with an offset arm which pushes a pawl up and down, this has a rubber diaphram attached with screw and washer at its end, the resultant reciprocating action causes the diaphragm to draw air in and then pump it out - aided by a set of very tiny reed valves. The electrics on all four pumps are ok, the rubber diaphrams have literally gone to pieces.

Vettech:
Very small - back together less the pawl and diaphragm.
