the foamy stream is a massive air leak. it could simply be the housing is not machined flat and the filter seal isn't sealing. or the hose fittings, or the primer itself.

More than one person in this thread in another forum saying non-genuine fuel filters caused problems similar to yours.
I avoid dealers whenever I can, have done my own vehicle servicing and repairs for the last 35 years and have always gone with Ryco, but am considering a move to Mann.

so jumped under it today to suss this fuel tank breather and can’t for the life of me find the bloody thing. do you have to drop the tank to see it? or am i just being a bit special today? pretty frustrated so that might not be helping
(someone pls draw me an arrow on one of the pics?)
opened the fuel cap and it definitely sounds pressurised, which i thought was normal tbh but maybe not
been trying to buy another primer, second hand but genuine, with the water separator so hopefully one of these fixes the issue

the breather is one of the three pipes on top of the fuel tank. it runs into the engine bay on the firewall. drivers side if i recall correctly.
that website is great, will definitely be saving that for future reference, thank you
right, i was looking at the chassis rail directly next to the tank, makes a lot of sense to have the breather come up higher. will suss tomorrow.
latest update.
bought a second hand filter assembly, installed it and the primer is cooked, pumps forever and never gets solid. sweet.
and the water sensor has the wrong plug and also didn’t help anything with the clear lines. so that was a pointless activity
however! the aftermarket primer i bought had an o ring on the inside lip of the filter as well as the outside (both at the primer side) genuine doesn’t as far as i’m aware. i took that out and left just the outside one and reinstalled it and it seems less foamy.
then, i lifted up the filter and held it at 90deg and the air in the line disappeared
i’m so confused.
also, to check if it was a blocked breather (not sure if this would even work, but i think so) i had it running and opened the fuel cap, but that changed nothing. outlet side of primer was still foamy
vid won’t upload so pics attached of holding filter up, bit hard to see the foamy fuel in the first pic
