Ok where is the fuel filter located on the 94 s10 blazers? Under the hood or by the fuel tank. The reason im askin is mine is runnin shoddy and i was thinkin maybe it was the fuel filter.

 

it is behind the framerail on the driverside right in the middle of the truck. Generally right under where the back door is, that is if it is a 4 door.

 

What's is the best way to releave fuel pressure on this truck? thx

 

If I am correct there is a valve under the hood on the fuel rail. Looks like tire valve, twist off cap(if there is one on it) and push on the valve inside it. Make sure to have a rag handy for the fuel that will come out.

 

A much easier way to relieve fuel pressure is to pull the fuel pump relay and try to start the truck. It'll relieve it without spraying fuel out...
