Agree on the hose...in fact they've always made the hose and ends ...that's what is used as far back as the 330's. The Blue & Red Cloth covered hose for example, on 330's & Daytonas is Industrial AQ.
The hose and ends are from their industrial division...but I'm not sure they make RU ends with the o-ring ends...Flares yes for sure. |

Aeroquip now makes ac hose and reuseable ends. Call Summit racing for details. They are braided stainless steel and SS ends. |

Definately splice if you can. A good AC shop will have a "hand held portable, manuel crimping tool" (not bench mounted hydraulic for your application). They use brass ferrels and crimp the ends on just like the factory fittings. I have one and it fits into some pretty tight places.
Don't let an AC shop talk you into anything to exotic or pricey. Look around until you find a real shop that can simply "crimp" new fittings and/or splices. Don't go the hose clamp route. The crimpimg tool and all fittings/adapters cost me about $800 6-7 yrs ago. Not cheap but they install profesional crimped fittings in very small/tight places.
You might want to install the dye penetrant and a little freon and find as many leaks as you can and do any/all ends that leak. |

There is a leak at the evaporator where the hose connects to the "rusty" fitting. Is this something that a competant A?C shop can splice and fix? Also looks like I have a leak in the condenser, which appears fairly easy to pull and then have fixed at a shop. The leaks are all in visible areas, so would I be better off having pieces spliced? |

I was afraid you were going to say that. You have one of those thankless giant PITA jobs facing you with the engine in. Unless you are certian the lines are leaking in a place that's unrepairable...you might think about leaving them alone. The amount of 134a that permeates the hoses themselves has been deemed negligible.
If you decide to proceed anyway, it takes two people and a perfect smooth extremly secure splicing of the old and new hose...then an hour or more in most cases of pulling, grunting, wiggling, pulling, jiggleing and groaning to draw the old hose out, while drawing the new hose in. |

Engine is in and since it was completely rebuilt less than 1 year and 500 miles ago, I don't think it will be coming out in the near future. At least I hope not. |

Is the engine in or out? |

Anyone ever done an A/C hose replacement on a 512bb? Is this a complete PITA or are there any tricks to make it easier. I have some leaks and figure i might as well do it all if I decide to do it. The car already has 134 conversion. |
