Hey, I've got an oil leak and I'm pretty sure its coming from the fuel pump gasket (at the rear of the block) Any tips and/or pointers of the best way to go about it? will i need other gaskets after removing exhaust manifold and carbs etc? Thanks - Milly |

If you have small / dexterous hands you can do it without removing 1/2 the engine. I did it that way last time and although it was some effort with twin carbs and LCB extractors, is doable. The only real main pointer I have for you is that when you reinsert the fuel pump, you run the inside of the flat lever that the cam pushes on against the inside of the block so that it goes in nice and easy. |

My tip related to the Goss mechanical pump (fitted between 65 and 75) If you grind the webbing of the casting on the pump body near the bolts you can actually swing a spanner easily from above. Also, there is a spacer between the pump and the engine block, there is a gasket on each side of the spacer. Thin spacer of about 5mm = Goss Australian made pump Thick spacer of about 10-12mm = English pump. The spacers are known to crack and leak. With twin carbs I just remove the left hand carby to get to the pump. |

I ground the ring end of a sidchrome ring/OE spanner thin, cut the spanner in half, then welded it together in an L shape. I also bent the shank slightly where it joins the ring end, so it's square to the bore. Much easier to swing around in there now and I can flip it over easily too. Clears the Goss pump casting fine. |

I use a 1/4 drive tube socket and stubby wobble ratchet. Glue the gaskets and spacers as one piece with the likes of 3bond, don't use silicone. From memory, some had bolts and others had stud/nuts, the stud nuts type is easier, if yours is bolt type grab 2 manifold studs from auto shop. |

And make sure you get the correct pump. There are different ones. Or.... Fit a blanking plate and go to one of my Electronic Fuel pumps ($50 post free) and fit it at the back in the rear sub frame with an inline filter before the pump... |

I managed to get mine off today. I removed the intake manifold and got down the back with a 3/8″ ratchet with a uni joint. It was done in minutes. |

I replaced mine once, later when the engine came out it got removed and replaced with a electric pump. |
