Flushing the fuel
I had a 'check engine' light up so stopped at a dealer - reported it was probably from a loose gas cap - code was cleared but I was told if it came on again I would need a canister vent valve as it probably had a leak. I had refueled a week or more ago.
I have a '97 F150 Ext Cab 4x4 with only 78K miles. Both the truck and my wife's '98 Expy (145K miles) have had the loose gas cap code before so I don't panic when the dash light comes on, still, need to get it checked tho.
It was $89 to check the code plus perform general insp and top fluids. Maybe it's time for me to buy one of those computer code readers - all I want to do is read the codes and/or clear the codes. If the code is something important, I'll give the code number to the dealer and get a repair. Any suggestions on a brand of code reader?
They also suggested, for my $89, that I will need a fuel filter soon and maybe a fuel 'flush' for $175.95 (TECK 861 SA 1008 - what ever these mean). What does a fuel flush accomplish? Seems to me the fuel is always fresh as I need to add fresh fuel when It gets low - so what gets 'flushed'? Is this simply flushing / agitating the fuel in the bottom of the tank to remove and sediment or moisture in the tank? Seems the fuel would be agitated just from driving over the RR tracks and pot-holes and with stops and accelerations.
