Baldwin BF7773 5 Micron Fuel Filter

This Baldwin Filters BF7773 is a new spin-on fuel filter designed to remove contaminants from diesel or petrol systems. It carries a 5 micron rating and uses an M30 x 1.50 thread for direct mounting. The housing measures 7 19/32 inches in height and length with a 4 1/4 inch outside diameter. Integral gasket and post seal are included for a secure fit.

Suits engines requiring M30 x 1.50 5 micron

This filter fits applications that specify an M30 x 1.50 thread and a 5 micron spin-on cartridge. It is not for systems using a different thread pitch, a finer or coarser micron rating, or a cartridge-style housing without spin-on threads. Buyers needing a different port size or filtration level should look at another part.

Critical spec is M30 x 1.50 thread

The thread size M30 x 1.50 and the 5 micron rating together determine whether this BF7773 matches the engine’s fuel circuit. Verify both values against the service manual before ordering.

Questions about this item

Which thread size matches my engine block, M30 x 1.50 or another pitch?

This filter uses an M30 x 1.50 thread; verify the engine or housing specification before ordering.

What does the 5 micron rating mean for daily driving?

It traps particles down to 5 microns, protecting injectors and pumps from fine debris in the fuel.

Does the M30 x 1.50 thread limit flow on high-output pumps?

The thread is a sealing standard; flow capacity depends on the filter media and housing design, not the thread alone.
