I was using a honda gx390 and triplex cat pump and it died mid job with the casing burst and inside was mangled.. So im putting an interpump 202 with gearbox at 21lpm and was wondering about feed hoses. I currently use a yellow 3/4 inch with direct feed as it was 15lpm on the cat pump so no need for buffer tank. Should i be thinking about using the 3/4 from buffer to machine and indeed using a 3/4 to feed the buffer. If i am better doing that rather than a 1/2 inch standard garden hose any idea where i could get a filter for that size of hose. Any advice from anyone currently using 21lpm would be great.
