Title: Fulvia Fuel Pump
Post by: Neil Cobb on 18 August, 2010, 06:35:39 PM
I've just spent the last 3 days fitting the engine back into my 72 1.6HF having nipped it out for some quick work 5 years ago.

Luckily I had the foresight to label everything, even though it was going back in again the following month.  Unfortunately I didn't label the pipes on the fuel pump so I don't know which pipe sucks and which pipe blows.  I'm guessing by the way the hoses naturally fall that the pump inlet is at the front and the rearmost pipe is the outlet.  Can anyone confirm this just in case I fill the fuel tank with air bubbles when I turn it over?

I've tried searching the Repair Shop Manual and the Tavola book to no avail.

Many thanks

Neil

Is there an in arrow and an out arrow?

Peter, thanks for the quick response.  You are rather assuming that the fuel pump is still visible to the human eye.  I've just been out to the garage and removed the airbox [for the second time today] but I still can't get a full view of the pump body and I'm not removing the carbs again.  My fingers are still aching from the various jobs around the engine and I feel that in the last three days I have done enough to complete modules 6 and 7 of the Open University Advanced Gynaecology course.

I have taken some digital photos from various angles in the bowels of the engine bay but the only markings I can find are Tipo 6012/70.  Shame I didn't check when the engine was dangling from the hoist on Monday morning...

I like your style :)

I did quite well with the engine, but let myself down considerably with photographing and labelling the interior. I've had to resort to working after the sun goes down recently so the kids don't see their old dad cry :D

The pump does have arrows on it - the nozzle closest to the block is the inlet from the tank (you can just see the arrows in this photo - I assume all pumps are the same).

Neil, thanks for the photos.  My pump is quite different to that in your photo as it is circular in section with brass pipes pointing rearwards at 45 deg away from the engine line.  I'm pretty sure I have them the right way round and I will do a test with a jam jar whilst I'm cranking up the oil pressure.  I'm going to have a look through some recent 2005 photos to see if I can spot it.  My knuckles are still bleeding from fitting the exhaust manifold so I'll probably leave that until tomorrow now.  A hot bath awaits: I think the hot tap is the one on the left, no the right, err...

This any help? it's on my Fulvia 2c.

Brian, it looks similar to mine [but not quite the same] and appears to be plumbed in the same way so that's quite reassuring.  I'll report back when my fuel filler cap flies off across the garden.

Sounds like it won't just be the fuel filler that'll be foaming at the mouth.

Its always a treat to see under the bonnet of a "humble" Lancia.  You expect the pair of twin chokes in a coupe but not a three box.  Its the same treat looking under the bonnet of an Appia Berlina and seeing just how similar it is to an Aurelia GT.  The reverse is when a rear engine Porsche pops its bonnet and you half expect a load of damp washing to fall out.

Disaster averted.  Had a proper look under bright sunlight today [that's why it's taken 5 years] and, low and behold, there are some arrows on the body as Peter suggested.  I was just one out from being perfectly correct!

Thanks, everybody, for the responses.

Now for the distributor timing...

Was it the same way around as my photo?

Brian, my pump is plumbed the opposite way round to yours but then it is a slightly different design.  Also your carbs look nicer than mine.  Hopefully I will see them at Goodwood.  I've discovered a live short on the car at the moment so I can't connect the battery up until I've rechecked all the wiring.  More anon...

sometimes the pipe orientation is due to how the top half has been mated to the bottom half, as I think it is possible to go integer 60 or 72 degrees depending on how many screws there are.

Every time I look in the engine bay now, all I can see are the two great arrows on the fuel pump.  I got the engine running today and it sounds pretty good.  Sadly the alternator is not charging and other than checking all the terminals, I'm not sure what else I can do in order to get it to work.

Any ideas out there?

I would be looking at the regulator unit, sticky contacts possibly.

I have a few specialist tools for electrical work.  Would you recommend the 1lb ball pein or the 5lb claw hammer?

I recommend Scotch - by the pint.

Tried pouring a pint of scotch on it to no avail.  Took the regulator off, opened it up, cleaned up the contacts [not sure it was necessary but it felt like I was doing something] then eventually found a faulty wire.  Replaced it, all connected up and it charges at 13.6-13.7v.  Towards the bottom of the range, perhaps, but perfectly adequate.
