Help please - no petrol

Thanks clan
In response to your suggestion I have ust been out and checked.
The rockers do move and I braveley (foolishly?) put my finger in the hole that the fuel pump fits into in the block and felt the cam move.

i guess the pump is faulty from what you say , its probably been hanging around on a shelf for 30 + years and maybe the valves or diaphragm have deteriorated , it might be a good oportunity to go electric pump but a mechanical one is the ultimate for reliability ..

I took the fuel pump back and although giving me a few funny looks they have agred to order another one hopefully for collection later today. I asked if they could find another make.
THe one I took back was a QH QFP102.
While looking on line last night I found another seller who listed the same QH part number as being as Volvo part 1336184 (and also gave AC part 461-150 and moprod FP 129). However another listed Volvo number 1336185 that could also be used on the 200/300/700/900 but from the picture it looked like the heat shield (spacer) and gasket had different shape cut out for the lever arm even though everything else looks the same.
To be sure I asked two volvo specialists, FRF Swansea and parts for volvo online, to check and to my total surprise neither can give a definitive answer! They both say they have no part number data for the 164.
I am now 99% sure it is in fact 1336184 that is correct, by looking closely at pictures from other sites that confirms my supplier got it right. So I did have the corect QH part, but shows how easy it is to jump to conclusion when parts look the same. On the other hand maybe the part was improved for the newer models and would work as well or better on the 164!
Looking forward with some trepidation to getting the new pump and trying it.

Just a quickie Jonathan: I think the 164 fuel pump has mounting holes different to those on the 200+ range. Thats before you compare length and angle of operating arm, but as I don't have a 240 pump in my hand or have number reference books, just my two-pennuth. Also I remember Simon at Brookhouse saying the same when I ordered a new one for our Amazon (the same pump for all 100-series cars now).
QH are as good as you can get nowadays, but as has been said before, perhaps you were sold old-stock, which had dried-out seals.
I realise it doesn't help but you're not the only one to have 100-series Volvo fuel pump problems. I concluded years ago that they are only fit for the bin if the car hasn't been run for a while - may be modern fuels don't help though.

If you are thinking of fitting a Quinton Hazel pump , i wouldnt hesitate and fit an electric pump , much more reliable .. !

New pump made by 'first line' just fitted together with new short length of flxible hose from metal pipe to pump but still nothing coming out the pump.
Sitting here I am now wonderering if I gave it long enough turning over on the starter. As I can suck petrol through (just tried it again) with very little effort in couple of seconds I would have thought a 30 second burst on the starter should have produced something in my jamjar?
Should I keep it going longer?
I cannot see any way I could be fitting the pump incorrectly?
The only thing I can think of to try next is to take pump off car again and try working it by hand from a can of petrol. If this works maybe I could then try feeding this to the carbs and see if the engine starts?
It is looking to me like the engine is not operating the pump but I know when I put my finger on it the cam that operates the pump moved when the starter was turned - but I did not leave it there long! Could it be loose on its shaft and slip when the resistance of the pump is applied?
As a last resort does anyone have any experience of rigging up an electric pump and by passing the mechanical one?
Any suggestions please

Thanks clan - your post must have come in while I was writing mine.

Quick update.
The new pump came with a single sheet instruction sheet (the QH one came with nothing) and did say that in some instances it was necessary to leave out the spacer/heat shield as it may be incorporated in the new pump.
The pumps looked identical but worth a try.
Easy to do until I found I had to find shorter bolts for this - and when done you guessed no different!
In the end I will probably have to give in and go electric but at the moment I really want an answer and I would refer to keep the car as original as possible.

Further update - the answer should be easy now!
The pump is still on the car (without the spacer/heatshield) and I put a pipe from the pump fuel inwards side to a can on the ground and the engine now starts and runs. The pump is therefore working and feeding the carbs. from the can.
I connect a clear tube to the (new) short flexible fuel pipe that joins the metal pipe from the tank to the pump. I can blow back into the tank without restriction and I can easily suck petrol from the tank and see it coming up the clear tube.
I connect the short flexible pipe to the fuel inwards side of the pump and there is no output.
If the pump can suck fuel from the can, and I can suck fuel from the tank why can't the pump suck fuel from the tank?
Help

Maybe the pump doesn't like sucking air?

Run the car for a few minutes using your separate can of fuel, so it's warm and the the carbs have some fuel in them.
Fill the car's tank-to-pump pipe with petrol, so there's little air left in it, then connect it.
Start the car (it should have enough in the carbs to run) and hopefully this faster running - faster than the starter motor - will get it to pull through the fuel.

I wonder if the lobe on the cam is worn, so it does not pump very hard? Never heard of that before though.
