Which Facet pump did you use Geoff? (there are several available for cars with carburettors)
I've been using Carter fuel pumps - I say plural because the first one died after very little use - maybe that was part of the problem. I gather they don't like infrequent use and they are cooled by the fuel itself. One good thing about the Carter pumps is that they are relatively quiet - you certainly can't hear my boot mounted pump when the engine is running. They also come with rubber isolating mounts. I have an Edelbrock carb on my 411 and use a fuel pressure regulator set at 5.5 psi. My pump is connected to the original fuel uptake pipe, but with hindsight I would look at mounting the pump underneath the car to guarantee an instant gravity feed of fuel. |

Fitted the pump this evening - went for a Facet Silver top. I used the same location in the boot but spent a bit of time making sure that it was unable to vibrate against anything and used the bobbins provided as part of the kit. On a brief test run it seems to work fine and to my ears is quieter than the SU - I cannot hear it at all when the engine is running.

Yes I'm using the pickup from the top of the tank. The flexible pipe had all been renewed last year (from tank to pump and pump to hard pipe going forward) in an effort to ward off E10 issues and because the old one was pretty ropey anyway which made the pump swap easy - otherwise I would have done that at the same time.
The Facet pump also comes with the ability to change the pressure by unscrewing the bottom and using a different spring (like the SU dashpot spring!). The carb on mine (a 500 cfm Edelbrock) wants a maximum of 6.5 psi and the pump as it comes is 6 - 7 psi so I changed the spring to a 4-5 psi one. Happy to post pictures - will have a read how to do it! Andrew Last edited by AndrewA; 06-10-21 at 05:11 AM. |

Brief update - using car daily until recently - and getting more impressed with it day by day! Handling is lovely and all is quiet within apart from what used to be slight whirring from the rear that is now becoming more audible.
With this in mind I dropped it off at Hardy Engineering with all my new bushes and they will go through everything. Drive up there was swift and enjoyable and was pleased to be shown three other Bristol axles they'd just rebuilt - it appears the car is in good hands but time will tell! |
