zd30 stalling randomly

yeah, lift pump seems like a much better idea, at least you’d see a fuel leak

i’ll check the bottom o-ring and tank breather and if neither fix it i guess changing all the rubber fuel lines isn’t a bad idea.

with the clear lines though, i had only reallyyyy tiny bubbles on the inlet side and then a foamy stream on the outlet side, so i’m taking it that suggests a problem at the filter housing yeah?
o-ring or the actual water sensor
filter is the correct part nb, new ryco filter too. maybe the new primer housing is dodgy

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
