Hi all,
An update to this - when pulling apart the mechanical fuel pump (again) i found one of the o rings had been eaten away by the fuel - hence the loss of fuel pressure. That o ring was less than 6 months old!
Anyway - o ring replaced and the engine is now singing again. I'll stick with the mechanical pump for now.
Cheers
Dave

Thanks Julian,
I can see where the confusion is happening - (apart from the manual!)- my cylinders are stamped as follows:
4. 5
2. 3
6. 1
Fan
Cheers
Dave
Confusion yes. Mine are stamped as Dave's. Is this method of head numbering to match the distributor cap numbering, whereas Julian's numbering is assending numerically from the fan pulley rearwards? Also Museo Motori states 1 4 3 6 5 2 as firing order. Would anyone here be able to post a schematic ht lead diagram perhaps in plan view of what works correctly . My distributor numbers match my head stampings at present. Richard |

So I now know that some heads are stamped to match distributor cap numbers and some are stamped to match cylinder numbers. Back to electric fuel pumps, despite some instructions saying horizontal mounting is ok, outlet at the top is logical to allow vapour to escape, so I have remounted my Facet pump vertically/ outlet at top as a precaution against previous suspected fuel starvation.

Regards using the Silver Top Facet, I bought one with a spring specified to 3 psi so I don't need the fuel regulator.

Good idea, I see the spring is also available separately. Looking at some engines of the period, I see some are fitted with yellow coloured fuel hose. Does anyone here have experience of this/ know of it's real world merits or otherwise? Richard |

Back to the distributor firing order I have marked the cap for future reference, as each rotor arm contact/ ht lead connection was not obvious to me until I performed a continuity test. Richard

You can get the Facet Silver Top electric pump with different rated springs. The standard spring gives 6psi and the optional spring is for 3psi. (There may be other springs available?).
I have a Solex twin choke 40 PAAI that needs 3 psi, so don't need a regulator since I've got a 3psi spring in the Facet. However a regulator will get rid of pulsing in the fuel delivery that apparently is desirable.
Before fitting the 3 psi spring I had fuel leaking from the carbs and the plugs sooted up realy quickly. Now its sorted.

Useful to know about the spring rates available, thank you. I have made this ht diagram for quick reference for anyone who may find it useful.

My PF Coupe does not have a reserve arrangement (I have had the tank refurbished and I would have noticed how many outlet pipes there were). I have a Facet pump in the well behind the left rear wheel arch. Previous electric pump (name unknown) gave trouble several times during a journey on a "smart" motorway and so had to go.

Hi Richard, regarding the Yellow Fuel Hose you mentioned. It is REGOSALVA and it was a period fitment on many Italian cars such as Ferrari, Maserati. Lamborghini, Alfa, Lancia etc. It is 5 layered, inner spiral wound spring, white string, rubber hose, yellow sheathing and a spiral wound outer spring. It is very strong and difficult to bend into a tight radius. The price is prohibitive at around £20.00 PER INCH! I don`t know if it is Ethanol proof, as the question didn`t arise then. You can buy it from a proper Ferrari specialist, but I suspect you will not.
Best
Jaydub.

I wonder what the prohibitive cost is due to?

In the US, I think its even more ridiculous!
The B20 had its hose remade like this, but it now sits in a box on a shelf! A simple black fabric fuel hose gets the job done.
