802a starved of fuel?

[Light in the Dark]

So finally got around to playing with my 802a yesterday. It seems the unit is getting fuel during the 'priming' stage, but once running... she runs dry about 30 seconds later. I can hear the pump running on both Prime + Run as well as Aux + Run... but is there a separate circuit for keeping the pump running while not in prime stage?

I was getting this, then changed out the inline fuel filter in case it was blocked, but am getting the same thing. The fuel/water separator I could not unscrew to save my life... don't know what the **** I am doing wrong, but these 5kw units certainly are crammed in the case (compared to the 10kws). I can't even get my hand to the front of the block to access the drain T (was flushing the system yesterday).

The 803's aren't any better for the fuel / water separator. I had to remove the separator and base completely from the unit and introduce it to my bench vise and strap wrench. And even then it came off in pieces.

As mentioned, the seperator is a pain. They age on there, I have had luck with filter wrenches. It IS a filter, so could be stopped up...

Howdy,
The spin-on fuel/water filter is put on by King Kong. I have totally destroyed everyone I have taken off. I mean destroyed.

The angle to get in there totally sucks on these 5kws. I feel like if I torque the assembly any more, I am going to break the base and the sheet metal which its mounted onto.

So past the PITA separator... anyone have thoughts on the fuel issue?

May take an air hose and blow out all the lines.

My first though was remove the fuel line after the 2nd filter and see how much fuel is making it that far... Then repeat down stream.

If you take the side cover off, you can get in at a better angle. AND STILL turn the filter into wreckage.

I wish the government had specified threaded PEMs for the backing nuts of the sheet metal, versus the integrated washer/nut combo. I dropped a few of those nuts into the sheet metal seeing if they were threaded in, or if they had backing nuts.

Going to probably need to find a source for extras, if my gut tells me anything.

 

[Guyfang]

Yes, you just might need to have a few on hand.

I gave up and ordered 100 stainless screws and nuts and am just replacing them when I have to pull a panel.

 

[Guyfang]

That is what I did, but ordered 100's. I worked on sets from one end of germany to the other, so just took along bags full.

Know the size offhand (as well as the mating screw I guess.. should just replace them all as I go).

 

[rhurey]

#10-32 x 3/4" Hex - Unslotted Drive Indented Hex Washer Head Grade 18-8 Stainless Steel Machine Screw

#10-32 18-8 Stainless Steel Serrated Flange Nut

1/2" might be long enough also. But I went a bit longer.

Howdy,
Go to this thread MEP-802/803 Filters and Parts
