Plumbers tape on Brass Fuel barbs?
« on: May 16, 2012, 01:59:33 PM »
Got my tank in, and now I need to run the fuel line. I have a 5/8 fuel barb that screws into the tank pickup. Should I use teflon tape with this? I believe the tank pickup (which also screws into the tank) is a progressively  thread.

Any advice? Tape? No tape?

Also, the barbs and fuel line i have is 1/4 inch internally. Is this OK? A 115 Yami shouldn't starve, correct?

Don't use the tape. Go to the auto parts store and get some of that black goop that is gas resist...use it LIGHTLY. Don't want it going in the tank.

Also remember to remove the anti-siphon valve. There is a pic on here somewhere, try the "search" feature :thumright:

If its pipe thread (NPT) which I'm sure it is, I would use thread sealer (pipe dope) as first choice, then teflon tape as a second choice.  Either is Ok, were not talking pressure here, but the thread sealer will help even the tightening, prevent gauling the threads and make it easier at some point in the future to remove the fitting.

If you search online for the 2002 Yam outboard  rigging guide you will find it in PDF ( I found it but can't send it from this thing) and that should verify the size for you, if your have any doubts, go bigger.  Thead tape or chemical resistant pipe dope is recommended.. Pipe thread (NPT) is tapered but is not self sealing..

I guess the best way is to check the nipple on the motor itself? I really hope all the stuff I have fits.

I will head over to the brain trust that is my local autozone and see if they have the pipe dope.

Marc hit the nail on the head with the galling.  Use a pipe dope that is fuel resistant.  Last time I picked some up at Ace Hardware.

I used a product called Seal-All (figured with a name like I couldn't go wrong :lol: ) Got it from ACE for $2-3.  reminded me of contact cement, maybe stronger.

SO,

Went to the shop late night on the way back from work and checked the fuel line on the motor. It appears to be 1/4 inch internal diameter. I'm thinking I'm in the clear with the fuel line and barbs I bought. I guess I'll find out when I put the hammer down and run the thing lean and blow it to pieces.

The rigging PDF didn't say anything about the fuel feed diameter.

Should have the deck glued and screwed this weekend if everything goes to plan.

Yamaha fuel line is a metric size, bigger than 1/4" but smaller than 3/8".  We use 3/8" barbs, the Yam line WILL go on the barbs, just a tight fit...

Bob,

Being that the 115 is a smaller engine, do you feel the 1/4 line will effect the delivery? It is a SMALL difference between the 2, but I want to be sure I wont have issues. The floor goes in TOMORROW, argh.

Christian,
Even on 115s I use 3/8"  Actually, the only 1/4" ID fuel feeds I've ever dealt with were on Westerbeke and Kohler generators...

annnnnnnnnnnnnnnnnnd I'm back.

5 dollars a foot....that sounds reasonable. West Marine preys on unprepared boaters.

Anyhow, got the barbs too. 3/8th it is.

Thanks again for the help guys!
