FASS fuel pressures....

[jwilliams3]

Lately I have noticed a drop by about a pound or so in the last month.

I changed both filter and separator with no real change in pressure.



Is this normal? Maybe a settling of the pump?



I am running about 13. 5 psi. constant.

If you are running an isolator, try refilling it completely with antifreeze. Worth a try. Mine recently dropped from 17 to 9. After changing the prefilter, main filter with no difference, I filled up the isolator on my Di Pricol gauge and it came right back up. Good luck.

Nope, just a sender.

Its a Westach fuel gauge.
