How do you replace the fuel pump on a 1999 Chevy Astro AWD?

Answer 1

# Remove the negative lead from your battery # Drain the tank (siphon or pump out) # disconnect fuel lines (requires a special tool to make it easy) This tool (actually a set because there are three different sized fuel lines) can be purchased for not too much money at a local parts house. # Disconnect the filler hose # Support the tank and then unbolt the tank straps # lower the tank # disconnect the electrical connections to the pump assembly # pull tank out from under van # remove old fuel pump assembly...there are several methods that GM has used to hold the pump assembly in. Most common is a rotating locking collar. It can be easily moved with a "BRASS" punch. WARNING!! Do not use a tool that will spark when tapped with a hammer...thus BRASS is a necessity. # install new pump and reverse removal procedure # after completion, contemplate the reason you took on such a major job...this is one that I have decided not to do again...a shop can do it in a half a day...it took me a lot longer and required me to purchase stuff I'll probably never use again.
