37H1247 - Diaphragm for Simms injection pump used on the 3.4, 5.1, 5.7 BMC lorry (truck) engine.
Diaphragm is fitted to lorry engines, but we have been asked for this diaphragm for tractors when old lorry engines have been fitted in as replacement engines.
Please see part number AAK77 for the tractor version. It is important to get the correct diaphrgam for your injection pump, so that it governs correctly. If you are unsure please contact us.
