I just bought a 1986 fourtrax 350(my wife took over the TRX 250 while I was deployed). It wouldn’t start and I’ve narrowed it down to the fuel pump. I called a local shop to get a replacement and he said he converts to to a vacuum pump. It seems like something I could do myself if I had some guidance. If anybody and has any examples with pics that’d be great!
Also, what happens to the cut out relay when it no longer has a pump to talk to?

Thank you for any info!
