I swapped out my nissan factory filter for the CAV296 when I had the 2.8TD engine. When the conversion to the Chev was done,Brunswick left the CAV in place. It wasn't until I added flowmeters to the diesel supply and return lines that I found out what the engine fuel system was doing. Long story short, the CAV296 is rated for 42LPHR, so it might be a good check to check what your engine demand is before swapping to the CAV - I liked the CAV as its glass bowl made it easy to spot water, however it was way under size for the Chev in N/A format and totally undersized for the S/C. I now run fleetgurd units rated at 300LPHR with a lift pump rated at 440lpHR. I expect demand to be around the 180 - 200LPHR thru the filter, with maybe 90% going back to tank
