I have seen installs completed where the gauge is connected to the bottom of the fuel canister and some to the test port. Is one location more accurate than the other? With installing the snubber is there a need for some type of teflon tape or loc-tite to prevent leaking? Can the snubber be installed in series between the braided steel line and electrical connection?
