Attachment: MINI Heater Hose Routing DSCF2370.JPG Question: I have a plate that may go over another plate that secures the hydrolastic metal pipe to the body as seen above. Is the other plate used as well but on the inside of the car or not used at all? |

It should be: Crossmember Gasket Lower plate with steady holes for fuel/hydro Gasket Upper plate |

If did that timmy, my twin SU float bowl would hit that assembly. |

The twin HS4 fuel bowl should clear the heater hoses easily. Attachment: Heater hose HS4 clearance.jpg

Bill B I see you are using 2 spacers on your setup for the carbies. How thick are those spacers. I am only using one spacer. Just wondering which is correct - mine or yours. Attachment: Mini 1 Point 5 SU IMG_0461.JPG

timmy201 Just wondering where you get the gaskets and the part number. |

The gasket is available from all mini shops as NAM9197 |

The specification for SPO41 includes two spacers for each carby to enable the one-piece heat shield (ex MG Midget) to clear the original Cooper S pressed metal extractors and the fuel bowl to clear the firewall. Longer manifold studs are also needed to accommodate this increased thickness. I understand the sequence is inlet manifold (AEG573), gasket, spacer, gasket, heat shield, gasket, spacer, gasket, carburetor. The spacers are part number AYA0210 being 0.3" thick. |

Thanks winabbey. Was about to say something similar, although I also thought the extra spacers helped the throttle linkages clear the 1-piece heat shield. However the sequence you list implies that 1 spacer was enough to clear. From memory, the fabricated extractors bent down and fitted closer to the motor than any aftermarket version. The 1-piece heat shield was awkward to work around so I made a 2-piece that helped a bit. For "cooperess", it isn't really a question about which is 'correct', it is just that the police Ss were the only factory-fitted HS4 twins. If 1 spacer works, go with 1 spacer each. Saves buying more - they seem to be very expensive for what they are. |

I suggest most SPO41 cars these days would be using aftermarket extractors rather than the fragile original pressed metal type. My car came with aftermarket style extractors which meant the one-piece heat shield was bent out of shape to clear them. The easiest solution in this case is to use a two piece heat shield which has a gap where the centre extractor pipe now sits. I have installed original extractors and heat shield as I wanted to return the car to its original configuration. Re the positioning of the heatshield and spacers I haven't finalised the installation on my car so the statement about heat shield positioning is my best guess. I hope to get back to my car this year to complete the restoration, at which point I'll know more. |

By the way, my theory about the position of the heat shield started when I noted two thin spacers specified. Surely it would’ve been cheaper and easier to use one thicker spacer in the circumstances? |

I’m guessing they used the standard spacers from the other HS4 equipped minis/other cars and it was more cost effective than making custom spacers just for the SPO? |
