Guess I'm a real Ferrari owner now - found my first fuel leak ; )

As you know, this really isn't a problem unique to Ferrari.

David's kit is top of the line. You will not find a better fuel line upgrade kit.

 

When I ordered mine, he mentioned he would consider making an upper fuel hose kit if enough people expressed interest.

 

I'm replacing every hose in my '85.

 

Replace very hose with SAE R30J9 fuel line. Not the typical R30J7 stuff fuel line, which is OK for vapor use, but not totally.

The fuel injection hose is J9. It is expensive.

Look for J9 printed on the hose. If you don't see SAE R30J9, don't buy it.

It's good you found the leak before you had a real problem.

 

Do NOT forget all the injector lines as well. I found several that were about to leak that a visual inplace inspection did NOT could NOT catch.

Verell has the kits.

 

I'm also adding modern FI and ignition with the supercharger.

 

Except it's J30R9

Fuel Transfer Hose (SAE J30R2),
Fuel Feed/Transfer Hoses (SAE J30 R6,7,8),
Fuel Injection Hose (SAE J30R9), ****
In-Tank low pressure Fuel Hose (SAE J30R10),
Low Permeation Fuel Fill and Vent (Vapor) Hose (SAE J30R11),
Low Permeation Fuel Fill and Return Hose (SAE J30R12),
Radiator Hose (SAE J20R4),
Brake Hose (SAE J1401),
Power Steering Hose (SAE J2050),
AC Hose (SAE J51-SAE J 2064),
Windshield washer Hose (SAE J1037),
Transmission Fluid Hose (SAE J2050),
Heater Hose (SAE J20R3),
Oil Hose (SAE J30R2-5)

No need for anything exotic.

 

I don't understand the enthusiasm for replacing old hoses with very expensive 'specialist hoses'

I replaced my all fuel hoses last year (the location of the leak that triggered the replacement would horrify the regulars here). My hoses appear to have been original (i.e. 30 years old), so no surprise that they started to rot.

I replaced on a like for like basis (i.e. rubber with a cloth covering), ordered over the web. The only 'specialist' item was the hose between the filler cap and the tank - this I got from Superformance.

Using standard fuel hoses meant that this was a very cheap job to perform. I will replace them again in maybe 10 years time.

 

Do you have to worry about ethanol in your gas???

 

All the new hoses on the market today are fine for ethanol. This constant rap about ethanol and hoses is another FChat/internet myth. Millions of cars are produced every day and are running fine using E10 and E15 ethonal and nothing is falling off or rotting. You have to get up to 20% ethanol before you have to worry about older hoses rotting from ethanol. Newer hoses are generally fine. And let's not forget about the many flex fuel vehicles being manufactured which can run on E85. Ask yourself what they are using for hoses.

Quote from GoodYear:

For Hot Rod 2011 article on fuel hoses:

If you feel you must have a boutique brand then go for it. Noting wrong with them but it's totally unnecessary.

 

Of course new cars are ethanol tolerant, but when buying hoses for an old car you need to make sure they are tolerant. When it comes to the many fuel hoses on the 308 the last thing I'm going to worry about is a few bucks; and I asked that question to man posting from the UK.

 

All new hoses produced for fuel use will be ethanol tolerant, whether they go on a new car or an old car won't make any difference

 

This entire ethanol thing has been carried to extremes by an industry trying to make a buck off it using scare tactics. Today you read about how bad ethanol gas is because it absorbs moisture out of the air (myth) leading to separation of the ethanol form the gas and this leaves an alcohol/water mixture in the bottom of your tank with all types of related problems. The real problem is, just as it was in the past, condensation forming on the walls of partially filled gas tanks and that water being absorbed by the alcohol leading to separation. But, this doesn't happen that much any more because fuel system are sealed these days. And, if you go back in history before E10 fuel, when gas was 100% gas, we used to add Dry Gas to the tank to prevent the accumulation of water from condensation (or other sources) at the bottom of the fuel tank. And what is Dry Gas? Alcohol! They still make it today. Add a little Dry Gas to the tank and the alcohol would absorb the water and go into solution with the gas. So, back in the day we added alcohol to pure gas to keep water form accumulating in the fuel tank. Today we blame the alcohol in E10 as the cause of water in the tank. It's all BS aimed to create a problem that doesn't exist so someone can profit of fixing it.

As I have posted here more than once before, in 50 years of motoring I have never added ant type of fuel stabilizer to any vehicle or other internal combustion driven device while stored and I have never had a problem with any engine starting right up when taken out of storage.

 

Really?



I have two friends that work on and restore old cars, you should hear the horror stories of what ethanol is doing to old rubber. So like I said, make sure it is a new hose and not NOS or an old reel sitting in the back of the parts store.

 

No one is talking about water, rust, or additives in this thread.
