Technical Fuel pump oil leaking

[Bernieszy]

My Tipo is pumping oil from the drain hole in the fuel pump I have checked the engine breather system and can blow air through the whole system.
Has anyone experienced this problem
Has anyone got any ideas why this would be happening.

I'm not quite sure what you said but if your fuel pump is leaking oil replace it.

When my one leaked my Tipo like to switch off when the revs dropped.

Leads to lack of performance and excessive fuel consumption.
