I posted a thread a while back saying that my 02 lb7 showed it was lacking fuel rail pressure upon fuel enrichment the p1093code. I haven't done anything to correct the problem and nothings come from it. Anyone at all know what this is from? thanks for your help.

clogging fuel filter,irrelivent of wether it has gotten worse or not that is the most likely cause.

which is the best fuel filter. dealer says there's is the best. does the dealers filter not last as long as aftermarkets due to filtering finer particles, will other filters plug the injectors faster.got the same code and just realized i have over 20k on filter ooops!!!!!!!! gettin one today

All the fuel filters for our trucks are made by Racor and rebadged. They are all the same as long as you get the new style.
