    i did my fuel filler hose and all of my fuel lines recently. i know there are other, probably better threads, but please folks, keep an eye on these things!

    Ferraris, boats, aircraft - it doesnt matter, FIRE SUCKS! i think 5 years is a good number for replacement of non fuel injected lines ? anyway here are some pics of my old filler hose. i did the carb/tank lines for the hell of it, so they would all be on the same time/inspection schedule. i work on airplanes too much i guess!

    if anyone knows what the heck the "A O USA" means on all of my upper control arms, i would love to know!

    :)

    not worth its own thread, but i had enough Swepco 201 from my 911 Porsche gearbox oil change to also do the 308. its been a few weeks and the car shifts great. the 308 shifted fine before, so i cant say it did anything one way or another. i do like the Redline 70W90NS, but i had to use what i had in inventory!!! :)


    just "FYI".

    Michael,

    I have a couple of notes to add to your plea:

    do ALL of the hoses, not just the big filler, cross over and supply lines, do the evaporative ones as well. I am here to tell you that they will PIZZ fuel all over if the tanks are full and you park on a side hill and you still have the orriginal fabric stuff. Replace it with the good stuff.

    #2, I used 300 psi rated rubber NAPA fuel hose for all of the supply lines and evaporative lines. it costs a bit more but is stronger, tougher - cheap advantage over the standard hose.

    BTW, the black car looks sleeeek.

    best,
    chris

    Michael,
    Can you tell us more about what hose you used for the carb and tank lines?
    My 77 308 is due for new fuel hoses too..

    Metric or standard? Is it the same size from fuel pump up to and through the carbs?

    Did you drain the hoses by pulling the fuel pump fuse and running the engine, or is that bad for it?


    Already did the fuel fill nozzle and tank crossover tube hoses (don't forget those!)

    Thanks,
    Greg

    I bought my stuff on-line. I'll find it and post where I got it. It was 7mm fuel line and OEM style clamps. I think it's German stuff. It does not have the fabric covering on it.

    The filler hose can be found at NAPA.

    Michael,

    the pic of that hose says it all. this has moved way up the 308 to do list now! what NAPA hose size did you get? is there a thread with all the hose sizes,

    Yeah, if anyone has a list of all the hose sizes and lengths that would be awesome. I think I'd like to replace all mine over the winter.

    I'm 95% sure that those markings are to help the factory identify which flexible bushing was used in the subassembly (and to make sure they get it in the right version car). I can't recall exactly, but mine were marked either "USA Aus" (USA version or Austrailian version) or "NA Aus" (North American or Austrailian). Same thing on the TR -- many components have "USA CH" markings (USA or Swiss) since they share a lot of the same components (that aren't used on a standard version TR).

    i copied this from the stick 308 Cross Ref thread. this info is very helpful and was posted my CHRISMORSE originally:

    "quote
    Fuel pass side carbs front to back 5/16" 6"
    Fuel drivers side carbs front to back 5/16" 3"
    Fuel drivers side back carb to pass side back carb 5/16" 13"
    Fuel fuel pump to drivers side front carb 5/16" 58"
    Fuel return line from pass side front carb to pass tank 1/4" 21"
    Fuel fuel pump to filter 5/16" 12"
    Fuel fuel tank to pump 5/16" 8"
    Fuel fuel filler to tank crossover hard line 5/8" 10"
    Fuel drivers side tank to crossover hard line 5/8" 5"
    Fuel pass side tank to crossover hard line 5/8" 5" quote"

    i have used the closest standard size lines on all of my 308s when changing fuel lines. there may be a place near you that sells the correct metric stuff, but there are none near me, and i aint driving all the way into "town" in work traffic to buy metric line. ( i live outside of Savannah, not in the city)

    Napa had the large fuel hose, part number 1055 for $16.89 a foot. they did not stock it, so i ordered 2 feet of it as my original hose was around 6 inches long. :) they only had 3 feet of it at the warehouse and gave me the rest free. i am sure i will use it on my future 308's / L cars.

    i have not done the cross over lines between the tanks. i *think* you have to use some funny size metric line on those. i have had NO LEAKS. i only bothered to check the fuel filler hose when i ran my wires for my new Crane XR3000 ignition. i saw the cracks in the hose and ordered the stuff the same day!

    How much of this crosses to the 328? I suspect quite a bit, but I would like to have all of the info before I start work. Thanks for the great information!

    I just replaced all my fuel lines too... and the coolant lines, and the two oil lines, and the breather lines, and a LOT of other stuff. Pricey, but highly recommended.

    And while we're on the subject - I've said it before, and I'll say it again - don't forget to verify the integrity of your aluminum crossover pipe at the *top* of your fuel tanks.

    This pipe allows the pressure to equalize in the tanks, so one tank is not fuller than the other. So, if you have a hole in this pipe, what's coming out? Gas *VAPORS*, which, as we all know, are the *REALLY* explosive part.

    The one on my former car, I found out, had been sawed through by a poorly placed stainless steel mesh-covered fuel hose going to the carb(s). Luckily, I found out before it was too late.

    CHECK THOSE PIPES - don't just assume that because they're aluminum, they're ok.

    I'm NOT a Ferrari tech by any stretch, but when I had my 328 fuel lines replaced in January there were fewer than Carreaper lists. I'm almost certain the injected cars have fewer rubber fuel lines.

    But this is an important thread. Even in my '87, one of the lines replaced was hardened and on its way to becoming a risk, and the cost to have this done -- for you other wrench-challenged types out there - wasn't bad. I think the parts and labor for all of it came to a few hundred dollars.

    I plan on doing this myself. I guess I'll just remove and label every hose and go down to NAPA and get replacements. Thanks a lot for the replies!

    Gene, just buy the 5/8 an 1/4 fuel line, about 4 feet of each ( i like to have extra) and do one side, say the fuel pump side up to the carbs, then do the rest. i had my car on jacks with the wheels and wheel well panels off, and let the fuel pump run a bit and then started the car to look for any leaks. after a few drives i took the wheels and panels off again and rechecked ALL of the hose clamps to see if the heat cycle made any of them loose. a few were, but not enough to leak.


    a very helpful tip on getting the NEW 1055 fuel filler hose on :

    we use Vaseline on fuel panels at work on aircraft fuel panels as a lube and a sealer. the stuff is petrol based and wont hurt anything in small amounts.( there are a BUNCH of fuel panels on an airplane wing!!!) i applied a lite coat of the stuff to the inside of the new hose and it slid right on. i tightened the clamps and rechecked them a few drives later. the filler hose clamps were still tight. i did not use the Marmon clapms as my original
    clamps were fine. so for really tight fuel hoses/lines , a little bit of Vaseline will help. the filler hose fits very tight and without the lube it will be hard to get both ends in and have the clamp in the right place to tighten it with one hand.


    i hope this helps !

    :) i need to start passing a hat around to buy the red Jalpa on ebay. my 911 hasnt sold yet and i am a few Gs short!!! :)
