Hi, I’m Ron and I’ll be helping you today.

Before we get started though,Please understand that I don't know your skill level or tools you have to assist us. Also understand that I can't see,smell, hear, or touch the vehicle either, so patience is appreciated.

My goal is to make you happy and get a great rating in return for my time.Sometimes I have to give you bad news that I know you didn’t want to hear, so please don’t shoot the messenger.

You can tell for sure by doing a fuel pressure and volume test with a gauge. It's probably easier to just replace the filter if it's that old.

Thanks, Ron

I know that it hasn't been changed,so I'll try replacing the filter first. Thank you
