Thanks for your comment...

Better suggestion is to leave your transmission in "regular drive mode" and have your transmission's fluid flushed every 75K. New fluid is the lifeblood of a transmission. I recommend a bottle of Lucas brand Transmission Conditioner at this time too....

What really is the use on this hard inline fuel pressure sensor? I know there is a 2nd fuel tank pressure sensor which effects filling up our gas tanks- But it is a different animal. I have a 2012 GMC Sierra C1500 5.3L I bought new. It now has 140,000 miles on it. I have only used original GM parts on this truck. New GM O2 sensors, spark plugs & coil wires were installed at 100K- Just for maintenance reasons. I had all of the AFM crap removed round this time too. I had a GM master tech install a non-AFM GM 6.2L cam and a GMPP Performance roller lifter set. Then a local programmer installed a mild 87-Octane tune. I had an old mass air flow sensor code 2 weeks ago. "Perimeters out of sync". It is the original mass air flow sensor and no maintenance had been done in it's lifetime, so I bought some CRC brand electronics cleaner and "refreshed/cleaned it". I had a Code P0171 flash up on Monday. Check engine light has remained on steady-No flashing all this week, and it has never cleared itself. I experienced a hard jerking while using my cruise control at 65MPH yesterday, during lunch. The truck ran fine this morning coming into work on the same 65MPH highway. I have an appointment on Monday to see an old GM master certified tech, who now works on the side, and is very good young man. Same tech cleared an alcohol monitoring sensor last Friday. He said my trucks was flooding itself thinking I had E85 in my gas tank?? Said alcohol content was reading above 61%!! I only run 87 octane 10% gas in this truck. I have no scan tools, nor diagnostic means here. Just curious if this fuel pressure sensor (PN# 13500745) is the same sensor that also reads the alcohol content?? I can not find it anywhere in my parts schematics. It is my understanding these 2007.5-2013 GM trucks used the very first, and rudimentary, alcohol monitoring sensors? If this isn't the one in the same sensor, where is it?? I believe the 2014+ GM trucks sensor was vastly improved for future use and moved elsewhere in the fuel delivery system?? Brainstorming in Texas....

Check PN# 19418403 These trucks still have a steering wheel position sensor too. Just a thought.

Yes.

How did this end???

"RAM IT". Take you existing cover off. Find a rubber plug, drill you OEM cover to match, then "plug-it" up. Newer RAM trucks have this feature & I haven't seen any broken down on the side of the road with the plug "missing". I have seen RAM's broken down for OTHER reasons though!! LOL!!! ?

I would buy a rear set of Belltech Street & Performance "lowering" shocks.

In that case, I would go back OEM from a junkyard truck. They only made a million on those trucks... LOL

Side note, aftermarket lights ARE cheep, but tend to fade rather quickly...

I would start simple. Try removing each horn & cleaning the ground contact 1st....

Tough to tell with these pics. But short of cracked axle tubes (very unusual), it would have to be outer axle seals. If you are loosing brake fluid, worn metal brake lines running out to the L/RT wheel cylinders could also be the cause...

You need to make a good parts counter "friend" at your local dealership. He could give you wholesale pricing & the parts would arrive FASTER & without any shipping too!! ?

What "Ianf" said above... ?
