Fuel lines under pressure?

Newbie question: OM says to drain tank before changing inline fuel filter. I will probably do that anyway to see what comes out, but curious...can you change in-line filter w/o draining everything? Thanks.

However, you do have to drain the tank in order to change in internal tank mesh filter (fuel outlet bung)

Two small long nose vice grips either side of the filter - replace.
As for the internal one, similar, Run the tank low (about 4 liters) clamp off the bottom and tilt the tank outwards - remove, clean replace. Leaving the lower connecting line in place works in your favor because it assists draining fuel to the lower side.
I carry a pair of long nose vice grips in my tool kit after watching a Gobium video. Great idea.

A handy, multipurpose strategy, Andy. I carry two of these little fuel line clamps.

They're not quite as quick to clamp on as vise grips (though it doesn't take many turns to get 'em tight), but they weigh nothing, so they don't make the fuel hoses swing around and slap paint when I'm careless in removing the tank.

Quick release fuel line fittings like BMW? Basic ones are cheap.

Easier on the rubber as well.

I removed the little fake petcock mesh filter when I did the low fuel warning sensor and changed the fuel filter
am really glad i did
bottom 1/6 of it completely blocked with gunk
it was pretty easy on 2014 model to disconnect the fuel line on the right side of the bike and let the fuel tank pee into a gas can
Had to be really careful to not run the pump dry
Also very glad that even with only around 1800 miles I changed out the fuel filter, removed the tank and flushed the tank out with fresh gas
lot of paint bubbles/sludge/gunk came out of the tank and quite a bit of particles/black looking gas from the back side of filter

I was going to say:
EFI= Yes
Carbie= No, in-line fuel filters were/are probably owner installed.

Nice debris find. For some reason folks don't go checking and cleaning out the petcock and filter like they should. Then wonder why the heck they end of having fuel issues.

I swear that some of it had to be factory debris/grease and paint or powdercoat overspray....
there were so few miles on the rig when i bought it
should I ever get a brand new ural I would clean that screen with 1st break-in service...

BTW: the napa gold fuel filter works great with some auto-zone fuel injection clamps
