Hey All, I have a heater valve blanking plate, and a fuel pump blanking plate which need to attach but I dont know what nuts/bolt to buy to attach them. Can i use nuts to attached the heater blanking plate? or do I need studs + nuts? and what size thread? For the fuel pump, there are already studs in the block, but no nuts, so what size nuts should I buy? Thanks! |

Blanking plate / heater connection on head is 1/4" UNF, you can use either bolts, or studs + nuts. Nuts on the fuel pump studs are 5/16" UNF. |

Awesome, Thanks. If I get nuts for the heater connection, what length should I get? I presume the holes aren't very deep? |

If it has nothing in there now, go buy two bolts, 1/4" UNF x 1/2" long. With a spring washer on each. Less hassle than studs and nuts. |

Kev, would I be mad if I seemed to think they were 1/4 UNC to the head? I screwed up a thread a little while back and seem to remember they were UNC... |

Nope, they are all 1/4 UNF unless someone has retapped them. Manifold stud holes are 5/16 UNF, rocker stud and thermo housing stud holes both 5/16 UNC. |

Usually all threads into steel are UNF and if the thread is in alloy parts, such as gearbox or flywheel housing it is UNC. |

True but there are exceptions, particularly for studs, eg oil filter, fuel pump and head studs screwed into the block are all UNC. But they have UNF nuts on em. |
