PCV for adding a fuel pump to Champion Inverter 3100

Ok, So There's no way I'm gonna pay someone to ship me all the parts to and an external fuel tank for my Champion 3100. The guy selling this kit sells all the parts minus the tank fro almost $250 (OUCH).

I have pieced together the entire kit on AZ for $130 so far but am stuck on identifying the PCV he uses in the video.

It looks like some fuel line to a barb Tee and then the PCV but I don;t know what pcv to buy. Any suggestions?

Here's my list so far to buy. http://puu.sh/oxGlK/4d600fb13d.png
  • i need to watch that video again
    but depending on where it is placed, it would allow intake vacuum to operate the pump without the reciprocal back pressure to damage the pump

    Biggest thing I found out is that the cap on the Atwood tank needs to be cracked or it built up pressure in it.


    sealed tank, with fuel being pumped out, would built a vacuum inside the tank
    sooner or later it would stop
    air must be allowed in, to take the space of the fuel being pumped out
  • what exactly does the check valve do? i have watched this guys videos before, i did not see this on his yamaha build? he used the crankcase vent that went back into the air filter box to run the pulse pump?

    my brigs rider doesn't use a check valve either, and its ported off one of the valve covers?
  • More money could also be shaved off by using plastic hose barb fittings as well as some comparison shopping.
  • Sure thing.

    Went great! Here is the parts list I used. All from amazon and preference given to Prime shipping over slight price differences because I'm impatient.

    Only extra thing was cheep clamps for the fuel line from the auto parts store, pipe tape, and a 3 ft section of 3/16th's fuel line to go from the shutoff valve to the fuel pump (The stock fuel line is metric (Don;t remember what size) and wanted a more common size to use for the fuel pump and to help feed it so it didn't bog down.

    Biggest thing I found out is that the cap on the Atwood tank needs to be cracked or it built up pressure in it.

    Ran the genny for 2 days straight on this setup.
  • Any chance of listing all you parts and letting us know how it went?
  • I believe you are correct. I have all the parts on order and will report when done.

    That knowledge is what costs $120.


    Lol that's expensive knowledge. (It will be more like $180 after I add in the fuel tank that is not part of his kit)
  • I think "Supergen" had an inexpensive kit
    a few years back, i just checked online, and its not listed anymore
    you might contact them to see if any still exist
