Intermittent shuddering

[Eagle1]

I've recently renewed my fuel pipes, carb car. It wouldn't start. I found my problem to be the concerned with the two pipes out of the sender. After replacing them the car started. Now I've only got to deal with the wonderful Pierburg end of life

You can temporarily bypass them by removing them, mark them first on both the sender unit and underneath the car. Get a helper to gently wiggle at the top end whilst your underneath that way you won't confuse the pipe orientation, hopefully. Add two pipes and go through the bung under the foam seat insert. It's a bit tight on the sender to fit them so warm the pipes in hot water and add a bit of lube. They won't fit in the standard orientation but will work.

Just to double check. Is this the correct seal for the fuel tank sender?

Does anyone know where I can get another sender unit in case this one breaks when removing it?

Seal looks right, cheaper one here.

Is your fuel sender the plastic type?

I have the original fuel cap, will this one fit it? Which gasket will I need for it too?

I've bought a new fuel pump in case that's the issue. I bought this one

Does anyone know where I can get the gasket for it? Weird that VW Heritage don't supply one!! Thank you

it should be a standard oring that presses into the back of the pump, you will need 2 as the spacer block behind it also needs on o ring.

Original cap fits, You won’t need any new seals, possibly some new jubilee clips depending on the condition of yours.

Ok cool, thank you

If you are replacing the fuel filler neck I would recommend you replace the rubber hose between the filler neck and fuel tank, they can become very brittle over time.

With the o ring on the fuel pump I searched the part number and size on line and then ordered a O ring from ebay, just make sure the o ring is ok with the heat and oil.

Part number and sizes.

I think its 049 127 311 A search part number online and 36 x 2.5mm comes up, I searched for a 1989 Mk2 Scirocco.

Hi Mark,

Thanks for the advice regarding the rubber hose between fuel filler neck and tank as well as the o-rings.

In the meantime, I may have found a fuel sender unit
