Do these gauges work well?, maybe because of the lower fuel
flow it's inaccurate ?
How often do you replace the filters? It's got about 150 hours on it now.
Thanks for the help
You can see if the Racor needs changing just by looking at it. If it is pretty well blackened, then it may need to be. If it is not, then it definitely isn't. What micron are you using? If 10 - 30, then your OEM filter may be crudded up with what passed through the Racor. If a 2 micron and your symptoms are accurately indicating a clogged filter, then I would guess your OEM filter has been on for awhile.
And yes, the gauges do work, as long as you are sucking the fuel through the filter and not pushing it. Sometimes these are plumbed up wrong and if you're pushing the fuel, the gauge won't be accurate.
