I am replacing my Fuel Pump on my a 318LM --- one problem that I am going to encounter is that the nut on the copper line to the Carb from the old fuel pump is fast on its way to being stripped... any suggestions?? I have tried wd40 but it is not budging...

Thinking ahead....

If I cannot get that nut off... I will need to replace that fuel line... what to replace it with??? It is copper... and the copper has done well so far so I would like to go back with it... but who makes copper fuel lines?? I have called some Industrial supply places that make hydraulic hoses thinking they may handle other types... they said no....

Thanks....

Go to a propane supplier. They can make one up for you with the correct copper and the proper fittings. Take you old one with you.

Can a flexible fuel line be used? Copper makes me nervous, vibration could cause the copper to crack, leak,,,and boom!

Use your vise grips to get it off then replace it with hose barbs and marine grade fuel hose, or find you a SS braided teflon hose in McMaster Carr and put that on there. Copper on an engine will work harden and crack.

Vice grips are a bit of a last resort. Flare wrenches are best, but you may have entered the vice grip zone.

I'd say he's in the vise-grip zone. You need to get some PT-Blaster to loosen up the Tread-lock that's most likely on the fittin' and take the tubing to gas shop or a good mom and pop garage/marina and have a steel one made or if you have a good hose shop in town they can make S/S braided hose rated rated for corn gas.

Just a note of caution; I've ran into more than one surveyor that was not happy to see a braided section of fuel line installed as they cannot tell what type of line is under the braid. It then becomes a red flag on the survey.

'Surveyors' are part of the socialist plot, like insurance. I don't let them near my boat.

try fluid film, wd 40 is mostly water and not really great for freeing up frozen parts. Be prepared to apply and give it 24 hours to do its stuff, check out their website

Just putting the surveyor thing out there for those that do use them!

What is fluid film ?

The stuff really works!

Hey no problem on the surveyors. Some of my best friends and even some family members use them.

Jerry,

That Fluid Film looks pretty good. Where are you guys buying it? Is it expensive in the spray can?

I use Boeshield T9 http://www.boeshield.com/ - developed by Boeing for corrosion protection on aircraft, but its expensive (even when I buy at wholesale). According to Powerboat Reports, "Our test of greases, oils and aerosols finds Boeshield T-9® and good old Vaseline are best buys in protecting metal brightwork."

The best penetrating oil I've found for loosening rusted or corroded threaded connections is PB Blaster. I would not expect a fuel line fitting on a carb to be excessively rusted or corroded. It should come right out with a good pair of vise grips.
