Fuel Pump Differences

Depending on where you live in the world and their rules it may be illegal to use this aftermarket pump. If you happened to be under a warranty it would void it..  If it failed and you damaged your plane and the regulatory authority said the pump was the cause an insurance company could easily refuse your coverage. If a mechanic installed this under the same scenario then he'd be liable in court.

Why open a door you may regret.
