What's a 'reasonably' priced fuel flow regulator to run with a 45mm Weber? I've got a mate's on at the moment and I was looking for a nice one with a gauge.

Whatever you buy you definitely need a gauge too. Purolator regulators were way out on actual ref their markings. Here's some pretty ones- http://www.vpw.com.au/Category/Index/360777 |

Best thing to use is a low pressure pump if you are running SU. With so called Fuel regulators I have not yet found one that does what it is claimed to supposed to do. |

I'm running a facet pump, but had got it in my head that somewhere around 3lb was the sweet spot. |

Not sure what psi the Facet pumps push , but i'd think somewhere between 2-3 psi would be adequate pressure . I used to run a Holley regulator on my old ski boat , ( 350 Chev , Dual 650 Holley carbies on a Hi Rise Manifold ) and it only run about 3 psi . |

There are high and low pressure Facet pumps, check the model specifications before purchasing, or run a regulator. It's also a wise idea to check the fuel pressure with the engine under load - I recently had a 1310 Cooper S engine running on a rolling road dyno when we found that over 4500rpm in top gear the reconditioned SU pump was unable to maintain supply. Fuel pressure figures were in the negative - a great recipe for disaster, especially on a competition engine. |

I stock Electronic Fuel pumps which deliver 2.5 to 4 PSI ideal for SU. I have fitted them to every Mini I own and even my MGB which has twin 1 1/2 inch SUs. I sell these for $50.00 post included. I also supply rubber mounts with them for free. just PM me if you want one. |

I've used the round regs as pictured with success. The pump I used turned out to deliver too much pressure. |

Definitely check with a gauge to ensure whatever pressure regulator you use is accurate. Have seen several similar to the original picture which are totally inaccurate, still providing over 6psi when it is supposedly turned down to 1psi. |

2-4 psi electric pumps (so called import pumps) in North America have worked in my experience. |

The round regs are rubbish. 3.5 pounds on a weber. The holey reg is the best option and can have a gauge added. Bear in mind most low pressure gauges are inaccurate unless they have a capsule movement rather than a borden tube. |

Agree l have a one of those regs (redline) ATM bloody useless, installed a gauge and no difference in pressure when the reg is adjusted. I've since bought a Malpassi with filter though yet to install fingers crossed! |

Malpassi had some quality problems in the past. I trust they have been resolved as i think its cool to see the fuel go through the filter in the glass version.
