    Default 504 fuel pump oil, newbie question

    Hey, bit of a newb question, when refitting my fuel pump on my ti, should I fill it up first? When it was off and cleaning it I lost a bit of oil, any advise appreciated, Im guessing I will anyway but just checking as I don't want it to spit all over my fresh engine bay paint
    Thanks

    Injection pump? They have an oil feed from the engine? Normally you won't pull that off?

    Fuel pump is at the rear of the car?

    Does not compute!

    Umm, yes they are supposed to have a particular oil in them.
    The oil line is there for long service interval protection of the pump. The oil of choice was Auto oil.
    Dexron 2. Dexron 3 is fine. There is a 10 mm headed level plug on the side of the pump facing the passenger side. Fill the oil into the filler hole and it will dribble out the level hole. The drain for the pump is a 13 or 14mm and it is very hard to get at under the pump. Of course it also lets the oil piss all over the engine when you undo it. Change the pump oil every 20,000km was the interval, I think. If you want the dinkum KF workshop manual specs, let me know.
    The reason for changing the oil, especially if it is run in the engine oil only, is oil degrades and loses lubricity. There is a tiny little cam in there with tiny little, close tolerance pistons to pump the fuel.
    Please don't rely on the engine to lube the pump.

    from memory yes ATF at 10-15 vis will work but it tends to be a bit harsh on the TI pump

    Castrol used to make a light oil to suit and would be worthwhile to chase up if you want the pump to last
