Well done. Helped me a bunch, and saved me a ton of money I would have spent on a new one. Thank you, and keep up the good work. Is there a known torque spec for a nip, or just a bit? LOL. Just kidding, thank you.

Thanks for the upload, my 1.9 tdi oil sump is filling rather rapidly with diesel, besides the injectors do you know if a bad seal/gasket on the tandem pump can let it in that way ?

[@jasonboi7466]

Thanks for this! mech told me my vac pump is leaking oil. It’s been hard to start for a while too, I was thinking it might be fuel pump non return valve failing but looks like it’ll be the vac pump. Got a stiff pedal too so all my seals must be shot! I’ve got low pressure to my turbo too, mech said it’s 300 when it should be 500 (Don’t know what unit he said). Wastegate is well noisy, it’s over boosting and has some hesitation, would you think this could all be down to the vac pump too? It’s just had a new n75

[@Naz9mm]

if its only a a tiny leak of oil and fuel. do you still recommend opening the internals to do all the little bits? or would the outer main gaskets be enough.. no other fuelling issues with pressure etc

Nice video. Why not buy a new one ( aftermarket ) ? Al the work that you put in it.

[@realjiver2]

I've noted that, the repair kit for the1.9 PD 8 hole tandem pumps don't include those small springs. Is that because they are not necessary?

[@garyparker5012]

So which part or seal actually fails in those tandem pumps
