Hi, I'm Ron and I will be helping you today.
Stand by for a moment while I prepare your answer.

Fuel goes bad in about six months and causes the fuel sysytem to become contaminated.

The tank needs to be dropped and flushed out and fuel pump needs to be replaced.

The fuel lines need to be flushed and the injectors need to be cleaned. Varnish buildup is evident.

Thanks, Ron
