    I have done a search and read most of the relevant post on how to replace the long heater and vacuum hoses that run up the drivers’ side of the car. I now have a specific question. It seems all of the instruction was for a 308 GTB(S) and I have a 308 gt/4. Many of the post refer to taking the back half of the front wheel well out. All I seem to have is a 4” x 4” inspection hole with a cover that is attached with pop rivets. Does anyone know if and how to pull the wheel well liner out? Or if I need to?
    I moved the fuel tank back and out of the way, unbent the two sets of metal tabs on the firewall but the hoses do not move. Are there metal tabs up front that I am not finding?
    Thank you for any help you can give. -Skip

    You will have to pull the wheel well liner out and get the fuel tank out of the way. I removed the side fire wall also (there are 3 aluminum pieces, one large in the middle and two small ones on the sides). Once you get that opened up you can really see into the void and makes the change that much easier. Attach the new hose to the old one and pull it through. Might as well do the vacuum line while you are there.

    Thank you Jay. I have teh tank out of the way and I believe the hoses are free and unattached in the back of the car. My real question is in the front wheel well. Is it just that 4 x 4 inspection hole or do you need to talke a larger part of the wheel well out.

    Could someone rename this Thread as "heater" hose not "seater" hose. Or tell me how

    I seem to remember just using that small inspection hole but it was several years ago! It's a tight space, unfortunately I can't seem to find a pic from when I did it. I'll keep searching but there are over 1000 pictures.

    A mod will need to change the title but I think most of us can figure out what you mean :D

    Yes, that little inspection plate that is riveted in give you needed access to the hoses. Right behind that cover the hoses make a 90* bend from the door sill and head up to the heater valve.
    To remove the left side fuel tank I had to remove the transfer gear cover, the front studs that for that cover, the brake disk and caliper and then it would come out.
    If you pull the panel behind the tank and the panel next to the rear seat you will have no doubt why the car is as loud as it is. There's no sound deadening, and the panel in front of the tank isn't really sealed to anything and the metal wall next to the rear seat is probably resonant more that it is any kind of sound block. I stuffed a bit of sound deadener from McMaster in there, but I don't think it will matter. And I only did the one side. At least it didn't add much weigght!

    Grease it up, get a neighbor, he pushes and you pull.

    I was able to do my 83 308QV by just loosening the tank and moving it back as far as it would go. I alternated pulling at the front and pushing from behind and was able to get both hoses in at the same time by myself in about an hour after taking everything apart. Lubrication is the secret. I used liberal amounts of dish soap in a pump bottle with a long hose on it to get into the tight spots. Once that hose got moving past the first tight bend at the rear, it pulled very easily.

    There is no way my car would have let go of the hoses just by pulling and pushing. Maybe the GTb/s will allow this or maybe my car was just posessiveof its OE hoses. Next to the back seat where the hoses go from high above the gas tank to down low through the sill there are two steel fingers that are bent over as a clamp to hold the hoses. These fingers are exactly like what is on the bottom of the frame member right next to the coils that holds those same hoses right as they point towards the engine. Thses fingers were not going to let go, and as I pulled on them the sharp edges of the fingers skewed and dug into the rubber, enhancing their grip on the hose. On my car I think the hose would fail - especially my apparently fragile 34 year old heater hose - before it would pull out of those two clamps. And without opening the secret front hatch you'd be pulling around a sharp 90* bend. It seems pretty unlikely that even well lubed you could pull that through. Perhaps the GTb/s is different or perhaps series 2 GT4s are different and you can just pull with lube. My car was pretty tough. I actually wound up pulling the heater hose one direction and then the vacuum hose the other direction because I couldn't pull them both at once and they were easier tlo pull in opposite directions for some reason.

    Brian, if I may, I have a picture - taken back in 2001, when I did this job - of those fingers and I'll post it here so that the others will get an idea of what it looks like (don't look at the rust... :( ):
