Bill V, its funny how you mention you'd like to get everything ahead of time (and that's great), but with a Ferrari, you'll always be running back to the parts store for something... Always. Murphy's Law. Good luck!  | ||

Here is a list of the hose sizes and lengths that I used when I did my 80 carded gtb euro last winter. Use these sizes and lengths only as a start. I am sure some things will have changed over the years (especially those with the fuel system). I used some 1.5" silicon tubing I purchased from Rutlands to make the small coolant couplers. It was exspensive at something like $40 a foot, but I only want to do it once. I also replaced every hose clamp with aba smooth style clamps (about $250 worth of clamps). Everything said and done replacing EVERY hose on the car except for the air horn line and the water drain out of the AC I think it came close to $1000 for everything (not cheep but need to be done, most hose were still original). listed by type, description, diameter, length Coolant drivers side heat exchanger inside to T 1/2" 16� Coolant heat control valve to T 5/8� 6.5� Coolant pass side heat exchanger inside to T 1/2" 36� Coolant engine to heater switch 5/8� 131� Coolant pass side heat exchanger outside to return T 1/2� 29� Coolant driver side outside heat exchanger to return T 1/2� 27� Coolant return T to large line to radiator 5/8� 72� Coolant exspansion tank to water pump 3/4" 20� Coolant exspansion tank to water pump 3/8� 20� Coolant 1.5 couplers on hard lines/water pump/ etc. 1 1/2" 3-5�x 9 pieces Coolant 1.5 90 degree bend on radiator drivers side top 1 1/2" NA Vacuum engine to one way valve 1/2� 9� Vacuum one way valve to brake booster 1/2� 132� AC dryer to expansion valve 5/16� 8� AC condenser to dryer 5/16� 21� AC compressor to expansion valve 1/2� 112� AC compressor to condenser 13/32� 134� 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� Washer from windshield washer tank to splitter 3/32�? 64� Washer from splitter to drivers side nozzle 7/64�? 11� Washer from splitter to pass side nozzle 7/64�? 14� Emissions coupler on valve cover breathers 3/4" 2�x 2 pieces Emisions dry sump tank to valve breathers 3/4" ?

While I've again learned a lot about the proper hose to use through this discussion, my original Question hasn't been addressed as yet--namely, approx how many feet and of what size hoses are needed to redo an '85 308? I'd like to purchase everything I need ahead of time to save myself 99 trips to auto parts stores this Winter. Thanks for any info, as always. | ||

I mis spoke when I typed in Silicone hoses as the Green stripe is usually a direct replacement for the silicone hose and has many advantages. The Green stripe hose is a better substitute for automotive use than Silicone hose. Read about it. http://www.gates.com/brochure.cfm?brochure=925&location_id=1175 | ||

Hans, Ed says he used silicone hoses for the heater hoses. The long hose from front to back is a heater hose. That was my question, Did he use silicone hose on the long front to back heater hose. Lets wait for his answer. | ||

I think Ed mentioned Gates Green Stripe. Not silicon, but still top-of-the-line! | ||

Ed, Didn't you use reg. clamps with the silicone hose and didn't you replace the long front to back hose with silicone hose? | ||

Hans, You will NOT be able to get the 5/8 hose in one piece for the full length however all hoses are available in silicone and yes they are all pre-cut.( most 3 feet except elbows) It sucks but that is the only way to get it. As to the clamps there are 2 kind. The shrinking sleeve and the stainless clamp. Don't confuse the stainless with the regular hose clamp as the second will damage the hose. The plastic sleeve is the ONLY safe way to go as you NEVER have to adjust. I have found the silicone hose from a race supply store for 1/2 the price than gates. They also have the 45 degree hose in silicone. I will provide you with the supplyer tomorrow. ( I'm traveling )I have used their products before and NEVER failed. You will save BIG BUCKS. | ||

Tommy: You keep mentioning 1 1/2 inch hose. What about 5/8 heater hose in silicon? Still need special clamps? Still must order pre-cut? (which seems a little bizarre) | ||

Hans, Silicone is the best hose that money can buy. I have seen also the 45 degree bent hose in silicone. | ||

Sam, silicone hoses do need special clamps. The best is the the kind that Gates offers. It's a plastic sleeve that you install with a heat gun. They will never leak and easy to remove. The hoses come in cut lengths. You will have to check with the local supplier. I do know that the 1 1/2 ID comes in 3 feet lenghts. | ||

How about durability (if I change hoses, I'm *not* doing it again!) comparison of Green Stripe .vs. silicon .vs. nitril ? | ||

McMaster-Carr has a great selection of hose at good prices. They have the best prices on Slicone and they carry a nitril hose that is wrapped and looks very similar to the original Ferrari hoses. Their catalog is on line at http://www.mcmaster.com/ | ||

I just put normal 5/8" Gates hose because that is the heater hose they had at my local parts store. For the brake booster I put a real heavy duty Gates hose in that I got at a hose supplier in the area. I wanted to make sure it wouldn't collapse under vacuum, which a normal heater hose mostly likely wouldn't anyways. It was the whore of the earth trying to get that heavy hose through. I think I will use steel braided on the fuel system only. For the heater hoses I'll stick with rubber until one blows or gets cut, etc making a gigantic mess. If that ever happens then I'll swap to steel. | ||

i Heard that silicone hoses need special hose clamps, is that true? Also anyone go in for steel braided hoses..expensive overkill ? I use them on my Jaguar whenever a hose blows or swells and I never had a nother issue ever..gives great piece of mind (also hole in pocket and a little difficult to fit sometimes) but looks great if you like non-stock look) | ||

Sounds like Gates is the way to go. Approximately how much of what sizes should I get to complete the job? And, about how many of those short connection hoses are there on the car? Am I correct on the sizes--ie 1.5" for the connectors and 5/8" for the heater hoses? Any other sizes for any other hoses? | ||

The silicone hose may be expensive but as diffcult as it is to replace the silicone hose will be around for a long time. | ||

Gates green stripe is not a silicone hose. Their silicone hose is white and costs near $60 for a three feet length of 1 1/2 ID. | ||

I used the Gates Green stripe silicone hose for the heater hoses and they should last the life of the car. I used Gates hoses as well on all other applications except the curved ones under the intake. All the hoses are easy to replace except the long heater hose through the rocker panel. It is virtually impossible to replace without removing the left fuel tank which ain't that easy either. I officially replaced every hose on my car during the rebuild. | ||

Good point Tom. Also someone here on the F.C. replaced the long heater hose from front to rear with a silicone hose. Seems like it was Ed Gualt. It should be in the archives under "silicone hose". You should also find the other posts on replacing the hoses under the same topic. As Hans said Gates green stripe was also used. | ||

The two small hoses under the intake plenum should be bought from the dealer. The material that they are made from resist high temps,and they fit perfectly. | ||

Probably wouldn't hurt if you guys would also chime in with brand of hoses. Last that I heard, Gates Green-Stipe was the only way to go. Still true? | ||

I'm considering changing all of the hoses in my 308 this winter and , being new to this, am wondering what quantity and what sizes to stock up on for this job. For instance, how many short , pipe-to pipe 1.5 " hoses are there on this model and whereabouts are they all located ? I'm aware of the 2 very long heater hoses on the car --are they 5/8" ? Aside from the upper radiator hose are there any other molded hoses that I'd need to get from Ferrari? Thanks for any help/ advice. |
