2.5 fuel pump

[mark_i]

M20 2.5 fuel has stopped working...
can we use a pump from a 4-pot as a temporary fix/?

looks like the return pipe line would need blanking off

You can use it as a permanent fix if you want. The actual pump is exactly the same.
Either block the second pipe with a short piece of hose and a bung, or swap the pump into your old frame.

Thanks Brian. Any thing to be aware of when resoldering the motor wires?

[Brianmoooore]

Just normal soldering things, like plastic melts if you get it too hot for too long. Wires must be the correct way around, or the pump will run backwards.

Then the pump blows rather than sucks,and no fuel gets delivered to the rail....
