Much needed gas filter change
- Today I got around to changing the gas filter, this must have been the original at 57k, boy the gas pouring out of that was filthy.
This took about an hour, I had to pull back the aftermarket exhaust pipe to get better access.
I used a AC Delco fuel filter and completed the job with some Techron fuel cleaner.
car runs very well and I am glad this is out of the way.

My '01 C-5 has only 25,000 miles on it, but I've changed the fuel filter a couple of times, as maintenance......and because the first "replacement filter", started dripping fuel from the output side seal. I'm suspicious that the ethanol fuel was the cause of the leak.

do you add any light oil on the output line to lube the o ring going in?

Absolutely...........HOWEVER, even though you lubricate the O-ring, prior to installation, there's always the possibility of dripping gasoline diluting the oil, so it can be a tricky deal.
Before I retired from full time work, I spent well over 30 years in the precision optics industry, primarily working with high vacuum equipment. Every piece of vacuum equipment we had on site, had at least 10-15 O-rings. I have plenty of experience with the use/handling of O-rings......

and lucky you that your car has the fuel filter along the driver's side frame rail.

So when the o-ring starts dripping gas, it drips right on to the hot exhaust pipe, causing it to immediately evaporate, therefore it takes a few days to track down the source of the gas smell. Those engineers knew EXACTLY what they were doing.....

now you got me rethinking, when i was done, I ran the car for five minutes jacked up and saw no dripping or anything, I never actually crawled under to visually inspect the connections.
I guess I would be smelling this in my garage by now if it was

After I put my new filter on, I started the car and did a search for any leaks - no, not with a flame......seriously, always check, you never know when one of these components you buy may have a faulty O ring.
BTW, I changed mine as i was hearing odd noises coming from the area of the fuel filler, so I changed the filter as step 1 - and that fixed it.
