WEN Generator adapter for Vacuum pump - extended run time.

THIS DOES NOT WORK WITHOUT DOING A "VACUUM FUEL PUMP MOD". - Requires a cheap honda vacuum fuel pump in line after shutoff valve and plumbed to modified valve cover. For no modifcation, I designed an adapter to make a GENMAX electric fuel pump work. I did the mod to not need 12v power for the transfer pump and its all vacuum now.

Designed this to put on my WEN 2500-WATT Generator. Fusion does not have correct thread pitch so to correct this when modeling. Rescale the Z axis ONLY to 81.82%, X&Y 100%.

Does Require an Oring for bottom seal.

O-Ring Specs OD 2", ID 1 5/8 - works with 2 files.
O-Ring specs OD 1-7/8", ID 1-1/2" withs only with "WEN_Generator_Vacuum_Cap" only. I did see issues with this smaller oring setup not sealing long on my other setup (GENMAX powered pump setup) might not have an issue under vacuum, but switched back to larger oring setup.

Requires Hand tap 1/4NPT and 1/4npt to barb fitting for your suction line. I have not tested performance of vacuum as i went to GENMAX electric pump setup. (also uploaded)

• Edited a stronger design (WEN), best to print on its side. Uses a smaller seal O-Ring OD 1-7/8", ID 1-1/2. Both would work well, just stronger with smaller seal and reinforced wall.

*Edited, went back to larger o-ring. added beefier setup and flat spot to print on its side. ABS appears to not be too effected (white discoloring after about 4 days on electric pumped setup, and smaller oring not staying sealed) but printed last one is ASA.
Orings come in HF standard size red boxed o ring kit (nitrile). Can use those or order viton ones off amazon.
