anyone used or using this type of TDO4

I dont run a filter on mine, the only issue i can see is the inlet would be pointing towards the bulkhead, IMO may be more likely to pick something up but would be tight against bulkhead too is say,

I dont know how grinding it back would go as youd probably be best grinding halfway through the 90

And as for swapping the inlet housing it has to have the same wheel etc
