Thread: How To: Upgrade Your Fuel Filter!

First off, there are NO pictures regarding how to do this upgrade unfortunately but this info comes from a trusted friend that's been working in the auto industry for 33 years. He did this on an '02 Chevy Impala and his '05 Bonneville. I was gonna do this on my '97 GP but the line never seized or broke so I didn't bother.

Secondly, this is considered an upgrade because some people end up breaking and/or twisting the line trying to get the fuel filter off and need to repair it. Sometimes the nut and line rots or seizes. It's also an upgrade due to the fact that this will make filter changes easier then ever.


Last but not least, Credit and Thanks goes to TurboMike321 for supplying photos and a simple walk through.

Did this to mine.. Makes the filter change so much easier.. Hope you don't mind me posting some how to pics

FYI: in order to choose your preferred brand of fuel filter.. just look up a 95 chevy caprice 5.7 to get yours

Damn that looks like a good idea. And a lot of rust.

Lmao thread-jacked the poor dudes how-to

No worries... I know what you mean.

I would be interested in trying this as well. Matter of fact I almost DID do this because I think the nut on my line is finally done for.

I was just thinking the same thing.

How do you put the brass ribbed connector peice into the hard line?

Nevermind, turbomike, what part number is that compression fitting? Or what size?

Yea definitely not a thread jack. Just had to do something for a how to because it's tiring when people keep making a thousand posts on how to fix the fuel filter line.

Might do a suspension thread and consolidate all the info. Too many what springs, which struts, will these wheels fit, etc....

Sent from my LG G3

Does the little clear rubber piece on the end of the flexible line come in the package or does it come on the hose? And the little brass piece with a hex on one side and then it tapers inwards, which way does that go in?

Everything in the cart looks good right?



The compression fitting says it has different attachments for 1/4", 5/16", and 3/8".

Thank you Mike! I've got it now .
