Fuel Pump Question

[ciaoflyer]

Does the pump need priming once fitted, suck it through, or should it just start by itself when the engine is cranked?

[Pete126]

The pumps are self priming but it will take a while for the petrol to come through, Electric is the way to go   It will also save the starter motor and the endless cranking

i have to admit that with an electric pump it will start straight away like pete says the advantages do show on start up.

Do you guys fit safety relays? If so, what kind?

[Pete126]

I wired mine through a relay supplied through the ignition switch,  But on my things to do list is fit a fuel pump inertia switch They can be picked up cheaply on Bday

Any tips on where to get electric fuel pump?

[Pete126]

As long as your 126 isn't putting out more than 105 BHP this should do the trick

Cool, My manual pump has three pipes this has only two, how to I fit it?

[Pete126]

You just block the return fuel pipe off.

[ciaoflyer]

You don't need the return then?

[eben80]

No you don't. The pump automatically stops running when the float chamber is full. If you had the return it would keep on pumping straight to the return rather I think.

That's not a bad idea. I  ordered the 5 second priming & ignition sensing VW relay because that's what I've been using in electric pump aircooled VW conversions. I hope that the ignition pulse in the twin will also make it work correctly for the Facet that's going in the Fiat.

Will this from 126FAN fit the BIS?

OK update, I have fitted and tested both fuel pumps I have an neither pump a drop of fuel, I have sucked fuel through the end of the pipe but still neither will pump a drop.  I assume there is no special procedure to fit these, you just fit and it pumps.

Think I will order a new mech pump as it saves messing with electrical connections and the pump fitted has worked since 2006!
