Thanks I need to put the eletric water pump to work

Hi Tiagus,
I would like to know how you get on with the electric pump, as I said before they work very well in race engines where the needs are a little different to stop/start normal road conditions.
The electric pump has to deliver enough flow to cope with full throttle conditions, will have a constant electrical demand from the charging system and is most probably a little heavier than the belt driven pump.
As you had made a bearing housing, shaft and pulley, it would probably be easier to make an impeller to complete the pump

Sorry but the presentation does not have to steel tubes for the site, as a water pump already working, stay on it I'll see if the pump works or not.

About the original water pump, I dont wont to brake another engine because of that.

You'll not get much flow with kinked hoses like that, too much strain on the pump and not much cooling. I'd look for alternative hoses as domestic garden reinforced hose won't cope with the heat either, end up going hard.

Yes I know, that is just to test the pump I'm preparing some stainless steel pipes for there.
