I need to replace my fuel filter. need to know where it is and what i need to do to access it.


Hi,

Regarding Fuel Filter - Under vehicle, driver side, below seating area, front of fuel tank, mounted on chassis in fuel line.

A device located in the fuel line to remove impurities from the fuel before it enters the carburetor or injector system.

INSPECTION

Fuel filters can be located in a fuel line, in the tank, in a carburetor, or in any combination of these. A carburetor often has a filter behind the fitting at its fuel inlet.

REPLACE

Fuel filters and elements are serviced by replacement only. Some vehicle manufacturers recommend fuel filter replacement at 30,000 miles (48,000 km). Always replace the fuel filter at the vehicle manufacturer's recommended mileage.
The fuel filter replacement procedure varies depending on the make and year of the vehicle and the type of fuel system. Always follow the filter replacement procedure in the appropriate service manual. The photo sequence below shows a typical procedure for relieving fuel pressure and removing a fuel filter.

I have 1988 chev c1500 V8 5.7. Truck turns over but will not stay running. I put fuel in the carb & it fires rite up but then quits. I took it to a shop & they replaced fuel pump, fuel screen, fuel...


The only thing left is the carb, Have it rebuilt, sounds like a needle valve or the float is sticking. Check the choke, make sure it's open first before having it rebuilt

No fuel to carberator


What you replaced is 3/4 of the equation. The only thing left is an obstruction in a fuel line, unless I am missing something, and assuming that all the replacement parts you put on are functioning properly. Hope this helps and good luck with your problem. I would check things like the fuse for the fuel pump, ect.

1995 GMC 1500 sierra loses power


The bad typing is hard to understand.I ll take a stab at it anyway.You replace the plugs,distibuter,feul filter, and the air filter.Did you notice that i dont even care about the sea foam garbage.When you replaced all that stuff did you do the spark plug wires or the rotor or the coil or the fuel pump?Maybe your mechanic needs to make a few extra bucks off that last job he did for you.Good luck

Stalling


Have you done a back pressure test on it? If you have no idea what I'm talking about, unbolt exhaust at heads or before the catalitic converter/converters. Try starting then driving it then. If that solves your problem, your catalitic converter/converters are clogged.
