What are the odds that i will be successful in removing and replacing my filter without destrying the lines? See picture. I've been soaking it in PB blaster a few nights in a row to prep.

Keep soaking it I believe one side has snap release other side two wrenches and try to tighten first then see if it will come apart is where line goes into compression nut line will probably twist line and break just have plan to make something up for repair for new filter. Good luck with repair.

Holy Smokes! You win the internet for today. The only one Ive ever seen worse than that was a VW Jetta in central IL that all the brake and fuel lines just fell apart when they were bumped during a transmission Remove, rebuild, reinstall.

For the love of god....DONT TRY TO HEAT IT UP WITH A TORCH!!!!!!! Liquid Wrench is your friend....and it will take atleast 2 cans and 2 weeks of soaking every day at that!

IMO, it would be a waste of $ for the cans and a waste of time.....All new lines and filter and hoses while you are at it.

Agreed.......I'd keep soaking it and make sure you ha e GOOD line wrenches when trying to loosen it. I think it's 20mm and 3/4" if I remember correctly....been about 10 years since I did one on the frame Iike that.

From experience, just take it slow and steady.....back and forth to try and break it free. It may come loose, I've seen worse. Patience my friend.

If that ails and you don't have a fuel delivery issue or drivability issue I'd just leave it and plan on sending unit replacement if/when the time comes to absolutely replace it.

If the truck runs fine you may just want to let it stay that way until it dies...
It may come off after soaking. It may not.

At this point, it has gone so far down the road to corrosion-ville, you may want to have new fuel lines ready to go when the can of worms is opened.

i'd be less worried about the fuel filter and more concerned about the rest of vehicle condition, mounts, brackets, brake lines!
looks like a death trap to me

Thanks guys. I've had this truck for 5 years or so. I can't believe ive never replaced it. Esp at 312k miles now. It runs great, just noticed a slight delay on cold starting recently. I have the PO's records and the pump has been replaced at one point years ago. For the naysayers, the brake lines were replaced a couple years before i purchased it.

I suppose I'll plan on a fall project of dropping the tank, and running new lines and pump while its open.

That settles it, they use some sort of "Super Salt" up in Maryland. At one point the pump was replaced? What point was that and was the filter done at the same time?

Your "slight delay on cold starting" tells me that your fall plans to drop the tank and replace fuel pump may be sooner than you think. The stereotypical symptom of a dying fuel pump is extra cranking on a cold engine....not a fuel filter plugged up. A plugged up fuel filter typically runs fine on idle and starts to sputter on off idle engine speeds.

Your fuel filter has been there awhile by looking at the amount of corrosion.....unless you recently drove it through a vat of acid! So it obviously needs replaced.

Due to the amount of corrosion on that fuel filter I would do a thorough inspection of everything from the trannsmission pan, rear diff cover, ALL brake lines, Transmission lines, emergency brake cables, ALL electrical connectors and grounding. But most importantly the CHASSIS. Makes sure it isnt rotted out heavily somewhere.

This vehicle needs to be on a lift.
