1164.0. "Alcohol in the fuel - Gas line Conversions?" by KAHALA::SUTER (Never too Hot!) Tue Apr 19 1994 13:44

    
    	I understand that late 94 or early 95 will bring a certain
    amount of alcohol to our gasoline. I don't recall the percentage,
    but the owner's manual as well as numerous warning labels for my 
    351 PCM, which resides in an '87 Ski Nautique, specifically warn
    against the use of fuel which contains alcohol.
    
    	I believe this warning is because the rubber fuel lines 
    are known to deteriorate at a much faster rate when any type of
    alcohol is run through them.
    
    	Anyone planning on replacing their fuel lines with something
    that can handle the alcohol? For me that would mean creating fittings
    for steel(or whatever) gas lines on the tank, water separator and
    input side of the fuel pump along with making up the lines themselves.

1164.1	oh well	MR3MI1::BORZUMATO	`Tue Apr 19 1994 15:09`	13
	I absolutely refuse to change lines. Mine are all copper, except for about a 12" section. I refuse I refuse {:) Jim
1164.2	Let's trade and I'll worry about the new fuel	SALEM::NORCROSS_W	`Wed Apr 20 1994 08:51`	12
	Mine are copper, too. Rick, why don't we just swap boats and you won't have to be concerned with fuel line swapping. My boat has a new interior (ok, a couple of years old), too. Also a ski pylon and motor in the middle of the boat. You wouldn't even notice the difference. On a more serious note, your boat uses a rubber fuel line from the tank to the engine? With the proper tools and fittings, you should be able to swap over to copper lines without much trouble. There is probably also special fuel lines now that will handle the new fuels. Anybody have a contact at a boat building place to see what they are using and what the C.G. regs call for? Wayne
1164.3	Check for "J1527 TYPE A1"	SALEM::NORCROSS_W	`Wed Apr 20 1994 09:08`	8
	Rick, if you have a Boat/U.S. catalog, on page 59 they list an alcohol and flame resistant USCG approved fuel line. It's called "J1527 TYPE A1" which I think refers to a SAE standard. If your existing fuel line has this marked on it, then you are all set. If not, then they sell everything you would need to convert to this style hose. I can give you more info (prices, etc) if you tell me your hose size (1/4" ID and 5/16" ID seem to be the most common). Wayne
1164.4	Different hoses for Different Folks	SALEM::ABRAMS	`Wed Apr 20 1994 11:43`	23
	There are different standards and for the types of fuel line. Ensure you have the right one that is required. The Standard listed -.1 is for type 1 fire retardant feed hose which may not be required for your application. The different standards are SAE-j1527 type A1, A2, B1, and B2. From what I recall from the standard is that B1 and B2 is a non fire retardant hose that is for alcohol enhanced fuels used on outboards and inboards where fire retardant line is not required. A1 standard is for type 1 fire retardant alcohol enhanced fuel feed hose and A2 is for type 2 fire retardant alcohol enhanced fuel fill/vent hose. The main difference between type 1 /A1 and type 2/A2 fuel lines is the pressure rating of the line. Hope this helps. George (JOY III) p.s. If you are replacing your fuel line and are not sure which one to buy I would check with the USCG to be sure.
1164.5	To BOOM or not to BOOM?	UNYEM::FRASCH	`Wed May 25 1994 17:07`	8
	Rick, See .3! It's right on target and you should have no problems with alcohol. If your present hoses/lines are flexible and not "stiff" you probably don't have a problem. But, ----- better to be safe than go B-O-O-O-O-O-M! Don
