Ferrari Mailing List: Replacing non-return valve, accumulator and filter

[Rui Gigante (rui.gigante]

Hi listers,

I'm currently replacing the non-return valve (fuel pump), fuel filter and
accumulator on my 328

Question is: since the pump has no fuel, do I need to prime it first?
What's the best way to do it? Is it enough to let gas flow into the
(non-running) pump? Should I loosen the valve when the pump is back in place
to allow gas to fill the pump ?

Any previous experiences welcome ...

Thanks

Rui
