Faint whiff of gas fumes near and inside the truck

NBS Flex KOEO spec is 48-54 psi.

Being a Flex, you probably have a fuel filter inline on the frame. Has that been changed lately?

Yes, new fuel filter installed almost a year ago in preparation for a big road trip. AC Delco.

OK, I'm pulling together my parts list to purchase for this intake manifold gasket job. Are there other 'preventative replace' type things I should do while in there? (I already replaced the camshaft position sensor within the past year. I also replaced the crankshaft position sensor, but it's not located near this work zone.) Here's my list so far.

Required

• Fel-pro intake manifold gaskets

Optional?

• 2 knock sensors (which brand?)
• Dorman knock sensor harness
• RTV to create a water dam/diverter
• intake manifold bolts (some recommend this, not sure why?)
• Clean throttle body (some say to replace?)
• replace MAF?
• thermostat

I'd rather do some preventative work while I'm in there so I'm less worried about our next long road trip.

Consider replacing the oil sender (AC Delco) since it will be easy to get to.

how did you replace that camshaft position sensor without removing the intake? I was able to do the oil pressure sender without removing intake but it was a bit of a bear on my back. I could not get to the camshaft sensor essentially next to the oil pressure sender.
Agree replacing oil pressure sender with removing intake since it's way easier. Recommend only using ACDelco for knock sensors but not the advantage line. If I recall, some people had good luck with Delphi but otherwise don't go aftermarket.

I found a YouTube that showed how to replace the camshaft position sensor blind. It was quite an odyssey and it took me about two hours as I took my time, making sure I could reach the part and two bolts with my hands and tools.

I'm already stumped on this project with removing the fuel injector connectors. The service manual isn't any help and I haven't found an external reference that's helpful, either. See attached images for my installation. The injector connector I have doesn't match the service manual. I figured out how to removed the retaining clip, but can't find a tab to push that will release the connector.

What am I missing?

Brilliant, I'm now unbocked! My mistake was dismissing later model Youtubes as not applicable. Thanks!

So did you have to use the pick? Or did they come out easier than that?
