What is the best method to clean all of the nasty stuff and glitter out of the Suction and pressure AN hoses after an engine failure?


I have a parts washer and have flushed the parts with mineral spirits and then rinsed with hot water.


Is there a better way?

No clue but the first thing that comes to mind is gun cleaning brushes and solvent?

I'm with you. They're not THAT expensive. Nowhere near as expensive as the engine they'll be feeding.

We shoot foam pellets through new hydraulic hoses after we make them.  We cap one end and fill with filtered mineral spirits and cap the other end.   Shake and pour through a paper filter and inspect/weigh the filter and inspect via microscope.  This is done on a few only to validate our process.  

I agree though to look at new ones.

Realistically I'd only replace the clean oil hose from the filter to the motor and any other hoses after the filter.

And flush the others.

The filter should catch anything trapped in the other hoses.

Clean the ends and buy new hose and reuse the ends?

New hoses and oil cooler as well unless you havs a $300 engine (and don't mind doing the swap again, soon).

Agree with reusing the ends but you'll never (cost effectivly any way) get all the fine metal particles out of the hoses and cooler.
