Advice for getting the fuel filter off?

[Motor7]

I bought the kit to swap out the frame mounted 3 outlet oem filter to a two outlet(cheaper) filter. The one on my MH looks to be original. The fuel lines are Stainless Steel, but for some moronic reason they used regular steel fittings which are pitted and rusted. I hosed them down with Blaster, waited a few hours then tried to loosen them....nope, nothing/nada. So, I hosed them down again and packed up the tools.

We are leaving in a few days for the beach, so I am not taking a chance that I will twist the fuel line, or strip the fitting. When I get back I will try again, so are there any tricks to getting these lines off without turning them into twisted spaghetti?

The kit is the Ultra one:

Maybe by the time you get back the blaster will help, maybe take the can of blaster with you and hit it everyday.


Maybe get a dremel with a small wire wheel, to try to knock of the rust.

Use line wrenches on both hexs. Pull one towards the other, in one motion.

I just changed the filter on ours, it's the 2 outlet kind. The fittings were pretty snug but the fuel lines did not twist at all. I didn't have any penetrating oil here, we're in an RV park, so I just sprayed them with WD-40. For some reason they decided a filter with SAE fittings and fuel lines with Metric fittings was a good idea. I hate these newer vehicles, you have to get out 2 sets of wrenches/sockets to do anything, 1 SAE and 1 Metric.

With visions of changing my fuel filter on the side of the road,from the first filter change,the filter and fittings have been coated with Fluid Film to prevent rust. The securing bracket hardware is stainless. Filter changes are easy,well as easy as anything can be in that location!

That's funny...I was grumbling to myself the exact same thing yesterday as I drug out both the SAE and Metric tools

All my spare parts are in a small suitcase that also contains a list of the wrench assortment that I will need under there.

I bought a set of wrenches at HD, after Christmas closeout. Contains both short and long SAE and Metric. When I saw the set for $20 I couldn't pass it up. They've been in the MH since I bought them.

Best way to go is with the wrenches twinboat posted so you don’t round off the fittings. Especially if there that tight.

I have cheap set that suck.....have to find a better made set.

I don't / can't wast time with those at work. I cut the line and use a repair line with a compression fitting. They are available at any auto parts store.

I hear ya, and I have done that w/brake lines. If they turn put to be stuck fast, then a splicing I will be.

Well I guess heating the fittings up with a torch is out . If you can cut the filter in half , then hold the fitting on the line with one wrench and use the other to turn the filter. That will prevent twisting the fuel lines. Another method is to take a dremel tool with a cutting disk and slit the fitting on the filter ,being careful not to go to deep. Then split it open with a large screwdriver. This will relieve the pressure on the threads and it should come off . Try tightening the fitting first . It sometimes works.

Don't dremels make sparks.
