I am have a problem where the fuel pump has now fuel in it every time I stop. I have to suck it into the pump to get it too start. It has been since I put a recon in it. It's a 1.9 Dg anyone got any idears. Changed all the lines and had the carb reconditioned. Runs a dream when you get it started but not easy to start.

Thank you

Push rod should be exactly 100 mm long
The gasket should be fitted in the correct way

Also check you have no air leak at the pump this will allow fuel to return down the line

Most likely a pin hole in the pipe or a bad seal on the tank to pump fuel line, this allows air back in and it drains down, this pipe is under negative pressure when pumping so no petrol will leak hence why you dont spot it.

If it drives you nuts, fit an electric pump. Line is quickly primed then but you do need good fuel line.

Good point there Ralph..
If you haven't changed your fuel lines.. now is the time to do it

As an aside, I had this problem if mine stood for more than two days. Its VERY frustrating I know. I could have bought a new mechanical fuel pump but to be honest it cost more than the Facet pump quite a few of us use now and good as mech pumps are, they don't compare to the immediacy of electric ones. A new mech one may still not cure the problem. With the electric one, essentially all you do is route incoming pipe to your mech pump direct to carb, and fit electric one just after your fuel filter underneath (needs to be close to tank). You can leave mech pump where it is. Remove pushrod if you wish.

Facet 60106 Posi-Flow Fuel Pump

Keep to the 4.0-6.0 PSI ones (model above) and don't be tempted by the cheaper no-brand square metal-cased copies. Ensure its a Facet. You don't need a regulator. Replace all fuel line. I ran new 8mm line front to back. No problems since. Search for ways to get power to it. I used the blue signal wire from alternator as it draws less than 2 amps but you could fit a relay or get the power from the coil. It should be off when ignition is off, for safety reasons - hence the need to tap into something sensible. Trust me, you won't get a dry line again - unless you actually run out of fuel.

They're noisy when line is dry - quieter when its not but a rubber mount helps reduce noise. I prefer the noise - I know its working then. An electric pump can sometimes cure bad running, backfiring etc.
