Hello - new MEP-803a owner here

You may need to stick a wire into it, if its plugged up. But its not a problem.

Ok so tomorrow I'm going to try taking it apart and doing the fuel lines. Any pointers for them? How do I get them all off? And anything I should do in addition? I have the fuel tank nuts but seeing as I just put 3 gallons in I don't want to pull the tank if I don't have to Diesel is expensive! I will figure it out but thought I should ask!

Even if that gets wasted, it's better than a full tank (or more if AUX is being used) being wasted when the existing one leaks the first time you run it overnight & it decides to spew. Then you are out the fuel & power. Changing them out is not fun no matter the route you go, but making sure it is done right, you won't even need to worry about it leaking again.

Better to drain the tank now when you have time and control, than later when you might not. I would suggest that as this generator is new to you, while you are changing the tank nuts, check for debris, slime, and crud in the tank, and wipe the inside clean. No sense in washing crud into your filters or worse.

There are several threads here that cover changing the fuel lines, but in general, they are just fuel lines.

All the best,

So I got it disassembled it except the fuel lines. They scare me a little. @CallMeColt do I need a heat gun or do I just pull the tubes off and on? The petcock worked great. The bolts to get the muffler off were a PITA though!

Pull, yank, cut. Doesn't matter. They're designed to bond after some head cycles to seal well. It's why those plastic tees are a throw away item in my opinion.

The hoses are on barbs, so don't cut those

 

[pstansel74]

What size hose clamps do you use? I am having trouble finding 1/8inch.

On return lines, I use zip ties at each line end. On the main lines to the metering pumps, you can use hose clamps effectively. Just find some 1/4" - 7/8" hose clamps, most auto parts stores, ag supply stores with bolt bins, etc will have hose clamps. You may be able to reuse the compression fittings for the pump side, and only use a hose clamp at the top feed side where the line interfaces with the rigid fuel delivery line.

None are needed with the OEM line as it is return line, not feed line. It will "bond" after a heat cycle or two & seal up. For piece of mind, a zip tie will do but again, not needed. It's why they're hard to pull off after they have been on. If you are using something else, get something that is the right OD for that fuel line, just don't over tighten. These don't get more than 10ish psi.

Success! I got it cranked and running. Still bits and bobs to replace but it was a good start to hear it running and not have it spitting fuel! Next up is testing the electric generation and taking a run up to Mass.

They sure are nice when they are running right
