Are you usingna genuine turbo carb or an hif44. I had the same issue when using an hif44 Makes no difference the carbs are essentially the same Yes i moved to the darkside |

Or a bigger return line. its 8mm ID already :( could go ten i guess but seems abit over the top oo just a thought, it may be the return pipe into the tank could be made abit bigger as thats 7mm ID PITA to do though Reading up on RTS Clutches On 21st Sep, 2006 Paul S said: Go on, be brave, put it in the car and tell us how it works.

You must have a restriction somewhere. Or a bandjaxed regulator. If something is worth doing, it's worth doing half of. |

Drop the return into a jerry can if the pressure goes down your return is the problem Yes i moved to the darkside |

tried that with 8mm return and same stuff just overpowers the reg and lifts the diaphragm probably the spring tbh they are the originals that came with the mettys 25 or so years ago Cant do, a weak spring or lifting the diaphragm would result in a low pressure restricting the flow back to the tank is the onlyway to increase the pressure Now either the regulator is doing it or something after the fuel outlet of the regulator is (since that is the point your measuring it at ) Yes i moved to the darkside |

fuel pump puts out 9.5 psi FPR is putting out 4 at idle boost @ 5/6psi its fine lol anyway its whether you can keep the fuel float chamber full and not lean off its not an injection car and havent sat it at 70mph for an hour so never runs out around town & a roads need a new FPR as soon as i hook up the injection pump it shoots through 40psi worth of fuel regardless how tight i screw down the FPR either that or a tougher spring >.< Good luck with that one. What is the pump flow rate at 9.5psi? What is the expcted HP of the engine? and what AFR are you running at full throttle? On 26th Oct, 2004 TurboDave16v said:

im going for a happy running turbo engine with an afr of around 14.7 full throttle is 15.1 not too bad pulling it out over winter to put a SC gearbox, better head, lightened flywheel stronger clutch, distributor-less ignition blah blah so not too fussed in maxing the power atm the "metro turbo" fuel pump is back in the box for now :) On 26th Oct, 2004 TurboDave16v said:

have two regulators, both diaphragms are fine one has a longer screw which i used, tightened right up with the injection pump (43psi) and it still forced its way through needless to say the same test with the red top and it returned fine may look for an aftermarket reg any ideas? When you say 'tightened right up' do you mean winding the screw all the way in so the threads don't show? You need to back the screw off to reduce the pressure, i.e. turn the screw anti clockwise when viewed from above. The screw sets the preload on the spring and this force acts on the diaphragm from above, fuel pressure acts on the diaphragm from below. Once the fuel pressure reaches a certain value the force exerted on the diaphragm from below will overcome the spring force and the diaphragm will lift, opening up the return port thus allowing fuel to return to the tank. Winding the screw in increases the preload and therefore your fuel pressure. If you've wound the screw right in I'm not suprised you're getting 43psi. Edited by neilj1678 on 19th Aug, 2013. |

14.7-15:1 is way too lean when on boost. you will end up with a holey piston. If something is worth doing, it's worth doing half of. |

John's right. 15-1 under part throttle cruise is fine, but under boost you need to be looking for 12 - 12.5 or it's goodbye Mr Piston ! |

Like I said earlier if the pump is providing so much flow that the retun line can't is being over powered so you can't regulate the pressure you need to fit the inline fuse to the fuel pump. Own the day

That makes no sense what so ever. The fact that the fuel pump can flow a great deal of fuel should be of no concern here so long as the return line has no restriction. I run a Walbro 255 (thats 255 litres/hour!) pump and standard SPi fuel lines without any problem. At idle, its all going back to the tank. also, I think you'll also find that TurboDave has stated that he runs a Walbro 255 with a carb set up without issue, so its very likely nothing to do with the pump.
