PS
is there anyone here who knows about elec fuel pumps? I may want to try &
fix this one. Autozone wants $199 for replacement, & Ebeay has some for
$70, but many say "all except US built King cab" which is what I have.
If I pull the pump I don't mind paying for replacement if it works but I
want it to work.
