I am trying to replace the fuel pump in my wife's B2500. I have raised the bed, removed one hose and tapped on the outer ring to get it moving. But I can not figure out how to get the high pressure fitting apart (see photo)

. I have pushed in on the clip hoping it would release the hose but it doesn't. I don't want to destroy the hose, so I'm asking for help. The video I have used to raise the bed and replace the pump shows completely different fittings and hoses. 4 instead of 2 and easy to remove push fittings. Not at all what I have. Any help would be greatly appreciated,

 

That is a typical "Quick Release" fuel fitting. There are a lot of tool manufacturers that make a tool for removing the connector. Just release the metal safety clip, and use the appropriate size tool to release the connector.

Here is a video link showing the removal process......

 

Here are some of the different styles of tools that companies make for these fittings.......any of them will work if they are the correct size for your fuel fitting......3/8" is a common size.

 

Here is a video where a guy made his own tool out of a Sharpie marker cap......

 

Thank you so much for your quick response. I did not know about these tools. The word "Frustration" across that video is the perfect description :-)
Thanks again.

 

You're welcome.......and welcome to the forum!

 

Well, the pump is finally out. But I thought I might save some others some grief by mentioning that I could not get the sharpy cap trick to work, so I bought the Harbor Freight version of the tool as it had many (like 6) different sizes. Unfortunately, it did not work either, as it's extensions are to short! So I strongly recommend you don't buy that tool. In desperation, I measured the line (3/8") and bought the tool at Advanced Auto which only had 2 sizes, but it worked perfectly.!

 

Hmmm....that's strange! From your photo in post #1, the fitting looks like it is the standard depth. You do have to push the hose towards the metal tube, prior to pushing the tool into the fitting in order to allow the "prongs" to be fully depressed by the tool though.......just wondering if that may have been the issue with the HF tools......or maybe the HF tool(s) are shorter than the manufacturers of said tools. I have used 2 of the different types of those tools that I posted, but my white plastic tools that have different diameters, were made by Lisle Tools, not HF.

 

I've only used such tool on stooopid heater core "quick disconnect" fitting on a 2005 Yukon. I got the Lisle tool from O'Reilly.

 

FYI - I went thru the reviews on HB website and apparently I am not the only one who found the HB tool to short. There were others that gave it a 1 star review and said it was to short. Guess I should read them first next time. I did pull the hose forward, it moved about a 16th of an inch, and tried the HB tool multiple times. I even tried to use the sharpie solution with the HB tool behind it to push. All I did was ruin 3 sharpie's. I soaked the fitting in PB blaster, it did not help. Did not work. But the AA tool had the fitting apart 1st try. I was shocked. The AA tool is at least a 3/8 inch longer than the HB tool and about $4 more expensive, but worth it. Thanks again for the help and happy holidays to all.
