Fuel leak on MEP 803a

[2mas-]

Hi,

Started up my new MEP-803a yesterday and it ran OK. Noticed the diesel return leaks in the fuel line i marked it the pictures. Is it possible to buy this fuel line new? Or can I put on a transparent fuel line over the steel line with a clamp on?

Its seems weird that the clothed fuel line is "pushed" in to the steel line, looks like a bad design..



Hope someone can give me some good advices here

You can replace this line, your choice to hunt down OEM or another solution. This topic is well covered in the forums. I would use the search phrase 'fuel return line' and see what you get. Many different options, but an easy fix.

The barb holds the fuel line just fine.

You could use Swagelok blue hose with push-on fittings
It is like all over the place for cheap
That stuff is good for medium pressure and never leaks and jacket takes higher heat .. OK

It's not a bad design. The rubber degrades faster than the cloth covering. Your leak is most likely at the bend because hard rubber that's bent leaks first.

I would replace all the return lines as soon as the generator isnt needed. Usually this requires removing the top lid and the cover by the fuel fill.

With rubber fuel lines, if I have a leak and don't know the age of the other lines, they all get changed. They're not far behind usually.

Wow, not sure about these gensets 802 here. Today the return from the injectors pissed diesel al over the engine. After 45 min run I heard this hissing sound thinking it was my air compressor but found a smoking genset.. I am not impressed.. that return line should not be hooked up to the inlet and be under electric pump pressure.
I felt lucky that it did not start a fire. .
We have three of these . By now I am surprised why the military used such a poor design...between the chafed wiring , poor fuel system and overly complicated electronics...
