I have the square looking one that is on this page http://www.facet-purolator.com/fuelpum.htm on my dino coupe right now. It ticks when I turn it on but i can't hear it at all with the engine running. Of course it's a pretty loud engine but so is a 308 I'm sure. From what I hear about Bruno's experience with the interupter facet pump, I think I'll keep buying these cheap square ones! |

Oh. when I had it mounted in it's original position with rubber grommets insulation etc. It was so loud that it was all you heard while driving the car.It even sent vibrations into the frame and vibrated behind the seats.I recommend a rotary pump unless you are going to boogie it like I did. Who knows maybe mine is bad although I contacted superformance and they said that is how it is. |

LOUD read my earlier post on this thread on what I ended up doing. Now it is very acceptable but it is boogie rigged. It does work fine . |

my 308 is injected, and has a banjo fitting on one end and a female fitting on the other. Made by Bosch in Checkoslovakia, the # is 0580 254 975
i believe this is the replacement pump. |

I can hear my Holley when the car is running and the door is closed. It is very very loud. It was around $40 or so but it is too loud for me. If there is a quieter alternative I will try it. I may try the Mallory. Rich what type of Holley is yours? Is there a quiet pump like FI cars have but with much less pressure than the roller cell pumps? |

Bruno and others who have purchased a pump from Superformance: Did it look like this? http://www.aldonauto.co.uk/shop/images_versions_large/470.jpg
Or was it square body? The square body ones that bolt to same pattern (but have inlet and outlet top and bottom instead of side to side which may require you to get some 90 degree fittings or mount elsewhere), are available at chain autopart places in the U.S. I got a 3-4psi one at Kragen for like $35 in a pinch and am still running it. I can hear it if the door is open and I'm running the pump only but once the car fires up I can't hear anything. Was going to replace the one I bought in an emergency with the Facet from Superformance but not if it is noisier than what I have now! |

George/Paul/Bruno -- the carb-308 fuel pump specs are in the 308GT4 WSM (page C13):
pressure = 3 +/- 0.5 meters H20 = 4.27 +/- 0.7 lb/in^2
capacity = 100 litres/hr
I don't know the max inlet pressure the needle valve in the carb can handle without direct flooding, but going to higher pressure would only increase needle valve wear on the early cars (without the downstream regulator), and on the later cars, the regulator (if it can keep up) would be near-constantly starving the pump inlet to to keep the pump outlet presssure down. An 8 mm fuel line feeding a 3L motor is like using a 7/16" fuel line on a mid-300 in^3 pushrod V8 -- it's already overdesigned a tad so no improvements required -- JMO.

I suspect you are right.If the volume is always there.I know the new one I just got is rated at 7psi.It runs fine.just noisey.I am told what you want is a rotary pump and that will shut it up.Of course supeformance didnt tell me that til after I bought and installed this one. I'm mildly disappointed with them.If I could return it I would. |

Thats interesting bruno, I would like to check mine one of these days. I got that spec from a weber book. If the spec is 7 and Im running 4psi, it probably wounldnt matter as long as the volume is there. |

CTK, thanks for the info....found out that the K-jet system requires 75-76 lbs of constant pressure, and 43-44 Control Pressure, don't know exactlly what that means, or how it's translated into PSI.
Place in Columbus, Ohio, Evans Automotive, has the replacement pumps and filters... |

The K-Jet system depends on continuous flow of fuel under high pressure to work properly. The original Bosch fuel pump is cooled via fuel passing through the pump itself. The pressure is over 5bar and the excess is returned upstream, without this overpressure delivery the engine will not perform efficiently. The Bosch pump is similar to earlier model Benz K-Jet engines type, the pumps are now made in Eastern Europe and not Germany but it does not matter. The pump is very quiet and has a faint buzz anything louder suggests a blocked fuel filter. The pumps are common to all K-Jet engines, with small differences in the way the electrical connectors are mounted or the central post for fuel is designed, a little DIY with adaptors will set you reight. BTW, make sure you get the check valve to prevent fuel pressure leakdown. Hope this helps.

Good point....that's what I was planning to do...get a Mallory pump from Summit...stay away from Holley...am running a Holley on the vette, and if not for the side mounts drowning out the pump noise, I'd go batty...at least the exhaust sound is more tolerable...kinda neat to hear all those horses exiting the side mounts.
What is the stock pressure, 4psi or 7? |

Why not but a vane type pump that you wont even hear and regulate it down to 4psi with an external regulator? Obviously the correct pump isnt being used because of availability so why not go all the way with a really good pump? My pump is alittle noisey at times and Ill probably be in the same boat next summer. Ill get a high performance aftermarket pump from summit or something like that. |

Holley is the noisiest on the narket, Mallory has half the decibel level as Holley. |

My fuel pump is very noisey. I think it is a Holley but I am not too sure. Has anyone found a quieter pump? |

And I would like to return a spare motor I ordered but there In England and by the time I send It there I might as well kep it. Returns are a problem. I am cheap and will tolerate a little garbage but a heads up would be appreciated. |

I sympathize with superformance not being able to get the good parts anymore. But they need to improve their communication with the customers and change the online catalog when something changes. I got a window motor that had to be modified to work and had to figure that out on my own - at first Mike didn't believe me until I showed him how the shaft was shorter. I also got a clutch cover that required the flywheel dowels to be removed to use it but wasn't given that information so I assumed it was simply the wrong product. Ordered a rotor and expected Marelli but got a no-name rotor that turned out to be flawed. Have heard many other things. I still recommend Superformance because of the prices and the fact that Mike has been a big help, but I tell people to check first before ordering. |

Magoo, Cant fit it in same mounting holes with 3/4 blocks. Can lower it about 1.5" and redrill and mount there. I unbolted it and wrapped it in more rubatex insulation and suspended it next to the fuel filter with panduits(nylon straps). It is now quiet as can be. It is just hokey looking.Superformance got back to me and said it is noisey and they dont have a source for rotary pumps anymore. I will run it till winter and then find a rotary pump. Or maybe leave it alone You cant see it unless you get the car in the air and look up.I am disappointed Superformance would sell one that loud. |

Bruno, Try using a rubber block about 1/2 to 3/4 inch thick between the pump and the mounting area using longer bolts. Make sure the rubber is not too hard. Then run the wire to ground. This is all in hoping the pump is not defective. |

Seems that way. I'll leave it alone till winter now. But it will have to go. I hate changing it and finding new one is loud too. |

That's the problem with aftermarket electric pumps. They all are loud. Think the quietest pumps on the market are Mallory. |

Yes,There was stock rubber grommet mounts there and I added rubber and wrapped the pump body in rubatex (insulating rubber tape like on airconditioning lines).It is still LOUD. I think most of it is vibration. It sounds fine if I jump a ground to it and run it hanging there. Waiting for response from superformance. it also isnt the usual high pitch sound it is a low rumble sound but at higher decibal rating. Hard to describe. Its LOUD. Where's Magoo when u need him?????????? |

Bruno, did you try to insulate the mounting with rubber? maybo rubber control arm bushings cut in half. Have Holley pump on my vette, was unbearably loud, then cut a control arm bushing in half.....amazing results |

I ordered one for my 82 European 308 (I don't know if a carbed 308 takes the same pump or not)from O'Reilly's for about $250. As I recall, NAPA could also get one for a few dollars more. I got the filter from T Rutlands, but don't remember the price. |
