Getting the fuel line fittings off the fuel pump? 98 V70XC

Post by DaveP189 » Wed Jan 11, 2017 8:19 pm

I mean, how do they actually attach or come off? Do they work similar to a fitting for an air tool line? Do I hold down the 'elbow' while pulling up the 'collar', or ... ???
The entire fitting will move up and down a bit, but don't seem to want to release. Every 'how-to' I can find shows a plastic fitting - these are metal (not rusted, actually a bit greasy, and I've hit them w/ a couple doses of WD-40).

You need to look at the connector from an engineer's perspective, i.e. how it was designed?

I posted the diagrams in the thread below.
Pay attention to the post from Nov 28, 2013: The key thing is to get the right-angle pliers UNDERNEATH the release tab.

Thanks, but those are plastic - mine are metal. And the tubes coming out of the pump have a ring around them, either as something for the fitting to grab on to, or to limit travel.
Or are you saying they're basically the same just more compact? I've tried a couple different ways, but don't want to break them (and spend days waiting for replacements).

OK, got it swapped and "it's alive!". :)
Was able to get the fittings undone with the "modified dinner fork" method, but discovered that I should have cut the hole a bit larger - was very tough maneuvering the lines/fittings to fully clear the ends of the outlet tubes during removal/installation. (I'll try to search out one of the better "how-to's" and add that.) I'll admit I was a bit confused with what was supposed to move on the fitting and what wasn't, but all good now. I'm also always over-cautious of breaking something because I live in a very rural area and have to order everything.
(I also mangled my right/dominant hand in an accident with a power saw about 4 months ago, and only have maybe 50% use of my fingers, just to add a bit more challenge to the issue. :roll: )
The retaining ring presented no issues to me, just a very big screwdriver and a lot of tapping to turn it off and on (like a bigger version of hundreds of electrical box connectors I've installed over the years). And zero leaks on the first try (yay!). I can also add that ~5 gallons in the tank is maximum to avoid spillage; mine showed ~6 and I got just a little bit - in fact if I leaned on the car to maneuver something it would spill out, it was that close.
3 on-offs with the key was all it took to prime and pressurize.
Only issue is it's got a high-pitched whine at idle, but I'm chalking that up to buying an off-brand fuel pump through eEuroparts ($109) instead of the Volvo part ($380). And I'm OK with that.
Thanks everyone for the help. On to the next things (passenger seat doesn't move, door chime)...

Dave - do those fittings release with the equivalent of a fuel line tool - something that goes up into the gap between the line and the outside line - same as at the front of the car near the intake manifold?

I bought a set of fuel line tools from Advance for under 10 bucks - made it back charging widows and orphans for the service quickly.

So quick question.. I was having the same issue getting these off and didn't do enough research, does anyone know how this goes back together?
There seems to be an o-ring, clear plastic ring, a metal clip, and a black plastic cylindrical piece. I believe I damaged a few of these parts and would like to know if anyone knows where to get replacement pieces and how they go back on correctly.
