The fuel line on my "60" 4104 between the secondary filter and the engine block is seeping fuel. It's not a spraying leak but more of an oozing through the rubber portion of the line. I have a few questions: 1. Can I replace this flexible line with a solid steel line? (There does not seem to be a need for a flexible line here because the filter/bracket is mounted directly to the engine.) 2. When I replace it, will I need to bleed the fuel system? (I plan on filling the line with fuel before installing to minimize the air in the line.) . | ||

NO What? no bleeding? no solid steel line? . | ||

vocabulary is wonderful,no solid line .if you fill the fuel line ,it shouldn't need primeing,may die once,no big deal,how's that ? | ||

Much better. I am cursed with being technically orientated and simple answers seem to raise more questions as I have a tendency to over analyze things. . | ||

If you have a place in your town that makes hydrolic lines,take the old line to them,if not,order one from LUKE-888-262-2434 | ||

It does look like a hydraulic line. Do you think one made up using AN fittings and braided lines will work? What is the fuel line pressure? . | ||

pressure is TINY compared to hyd. pressure, if you take your old line to them,about half the time they can use your old fittings,saveing you$$ | ||

Yes, AN braided line will work fine. Fuel pressure is approx 55psi at full fuel. Good luck with your repair. | ||

Al or steel AN fittings are OK but brass is better. This line is not under pressure, ordinary auto fuel line will work fine if the wall is not too thin. This is all suction at this point. The mechanical fuel pump is at the end of this hose opposite the filter. | ||

Fuel line pressure is usually below 100psi (unless it's a newer engine with high-pressure injectors). Hydraulic lines can handle at lest 10x that rating (some even higher). Make sure you have the same inner diameter so that you don't choke the sysytem. I'd look for brass fittings if you can find them - they are more durable. Also, don't use teflon tape on the fuel fittings - small chunks of teflon can squeeze into the line during compression and clog up an injector. If you go to a hydraulic shop, they'll have copper compression seals that won't leak - or screw up your injectors by contaminating your fuel system. -Tim | ||

uncle sam invented your steel fittings,they have lasted you 45 years,they will last another 45 years,after that,there will probably not even be diesel engines | ||

It has nothing to do with longevity. Steel to steel (or anything else) rusts, brass doesn't and will always be easier to remove. Since it is softer it also seals better. Al corrodes even worse than steel, especially when attached to steel. Brass won't corrode no matter what connects to it. Most people working on old vehicles (Or airplanes) found this out long ago. I won't use a steel fitting on anything. |
