91 Ls400 Fuel Filter

[vyhanh]

Hi,

Last night, I changed my son's 91 LS400 fuel filter according to lexls.com instructions. I may add that it would be much easier to undo the 2 bolts that attach the filter to the frame and also undo the bolt of the bracket that wraps around the filter. It is because with these bolts loosened up first, it is much easier to unscrew and screw the filter.

I got onto ALLDATA website and found out that you can disconnect the fuel pump from the trunk and stop the gas flowing thru the fuel line at the filter.

Checked vol1 of manual: Did not say specifically about fuel filter but for other components: every 36000 miles.
