Plenty of hours in the shed lying on concrete over Christmas playing with the fuel system and the mechanical lift pump appears to be dead.

At the moment i have swapped to an electric pump and may keep it as I can buy electric pumps off the shelf in the UK.

What do we all do with the old pump? Leave it in? Can you buy a blank to cover the hole? Make a blank?

Thanks
Jordi

A blank cover would keep diesel fuel from mixing with engine oil (from a cracked diaphram).

It wouldn't be hard to saw one up out of a piece of steel plate.

IIRC the 6.2 uses a plate with the pump, so you could probably pull that one off to use as a template.

I'd cut a flat plate out of 1/16 or so aluminum take the arm off the old pump and reinstall it over the blanking plate. That way all your fuel connections in the front remain intact.

Would that be needed? I’d have no pipes there.

You should have 2 factory lines at the pump. With the pump being the junction between the 2. Did you mount your electric pump 8n the front not back by the tank lower than fuel level,as is normally the best place to mount a pump?Pumps push better than they pull if you mount an electric pump in the front thayvare over worked and don't typically have a long life. The shorter the fyel run to an electric pump the better as long as you keep it below the level of the fuel and away from hot exhaust.

Its not mounted anywhere yet. Running off a jerry can as all the fuel lines are messed up.

I need to investigate further with how its all been piped up. Have another post about binning the change over valve and swapping to 2 electric pumps.

Ideally i want to take the intake manifold off and run a new metal pipe off the injection pump to the bulkhead. Flexi and/or metal pipes down, along the chassis to the tanks, split it with a Y, none return valve either side, pump, tank.

Not 100% sure how efficient it would be compared to the original change over valve?
