Of course they create a partial vacuum, i never said they didn't, what i meant was they will push fuel higher than they will suck it!

Go on post a picture of your nipple suckers in situ

probably!

Heres another spanner in the works to think about though.......i had a look on the separ website and there is a nice cross section of a filter showing a bleed screw at the top.
see my point? if the bleed screw it to get air out, then the primer has to be before the filter or you will be pumping all day(ooh err) and sucking air in

I give up! either way works

No, we're way behind JSP's 'changing gear oil' thread:

the 10mm nut on the separ is more for back flushing the filter, open the tap on the bottom and release the nut on the top and it pulls all the crap off the filter into the bowl, back flushing works quite well, imo only recor or separ are worth fitting

Priming Bulb Before or after Filter ?

The priming bulb should be after the filter.Fitted in the vertical plane before the engine.If fitted before the filter there is the potential to burst the filter element medium and allow unfiltered fuel to the engine.The priming bulb would be operating in unfiltered fuel and the non return valve subject to debris contamination and hence loss of priming efficiency.Use O.E.M primer for your particular engine and S/S crimped pipe fittings,steer clear of jubilee and plastic ratchet type pipe fittings.Only M.H.O !

Is anything about an outboard set up simple except for the tucker using it?
Will leave it as it is. Mines after a water separating fuel filter, that make any difference?

Yeh, there's the right way and the wrong way! And it seems the majority are yet again wrong!

Do you include the OEM in that statement who fit filters in the powerhead after the primer
Once again my mate who works for a filter manufacturer has clarified things,
aparently a water separator can go before or after a primer,but the primer should always be close to the tank , a micronic filter should go AFTER the primer and after the fuel lift pump due to the more restrictive nature of the filter medium.

Who really cares. It isn't really going to make much difference where it is. And it only really matters if you have inbuilt tanks. A portable 20 litre or so tank doesn't really need a filter, hence the reason why the motor comes with a fuel tank and fuel line that doesn't have provision for a filter.

I only fit spin on water seperators to outboards (60+ hp) as per the manufacturers instructions. And then only if the boat has integral tanks. At one time we were informed by Barrus not to fit anything to OPTI's, as they had their own filter on the powerhead, this has now been revised to a mercury style spin on and a bulkhead fitting.

When asked by the customer for something in excess of that, I fit a Racor, as they seem to be the only ones that are approved for petrol, most of the separ type filters seem to be for derv only.
