Suggestion
If you have replaced the fuel pump then the first thing is to make sure you pour petrol into the chamber around it ..
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Ok I give in, I'm going to ask
I have had all fuel pipes off the engine and back on, changed the fuel filter, installed a new Walbro TI Automotive fuel pump with larger output.
I'm out of ideas, problem I have is no fuel coming to the engine, i switch pump on via durametric I can hear it and feel vibration but no fuel :dont know:
Ive changed polarity on the pump supply to no avail.
I'm guessing air lock ?
any advise please??
cheers

If you have replaced the fuel pump then the first thing is to make sure you pour petrol into the chamber around it .. basically if you stick 5 litres of fuel in the filler this should do this as the design allows fuel to go over the pump when refilling .
If this chamber is empty you wont get any fuel out of the pump .
As this is a saddle type tank then you have suction jets , 1 for each saddle .. these work on a venturi effect by pumping fuel down one pipe into the saddle and sucking up a larger volume .
It's possible you have an issue with either of these .. to remove you press the tab in on the battery side of the pump .. but as you have already changed the pump im guessing you know this lol .
To me .. it sounds like your a little low on fuel as im struggling to see a new pump ( when the old one worked fine ) to be faulty .
Overview below .. C4 is the same tank as a Turbo ..

Great information thanks,
these diagrams I have not seen before, this puts a little more meat back on the bone for me to get stuck into,
Off to get my tools out, I might have it going for Dinslaken ðŸ‘😀😂😂
Please dont reverse polarity the pump again
Sparks and fuel worry me so obviously take precautions .
Start by making sure the pump is either covered in fuel or you pour fuel over it .. We can investigate further if req .
Ok
I firstly took the 'lid' off the fuel tank, the pump reservoir was empty of fuel, but more worrying, the small flexible black rubber pipe was split length ways 🙄
So I have put the original Porsche ones back on as they looked perfect and decidedly better quality than the new ones supplied with the pump.
I now need to get more fuel so it's all covered to rule out fuel starvation, I feel once I get the fuel through it will be sorted, so off down to the shell garage in the morning, currently around £1.65
The Very, power stuff 😀ðŸ‘
