Fuel filter

The filter should not be in the engine compartment. Most people put it in front of the engine, under the (rear) package tray. I have 2 one right out of the tank and one in front of engine..

The filter can be in the engine compartment, as long as it is on the SUCTION side of the fuel pump, not the pressure side. And hoses should be attached with correct size and type hose clamps. And the filter should be supported somehow, not just left dangling there freely.

Please kindly explain why have to be in SUCTION side ? Mind you my Fuel Filter is on the Pressure Side and inside the engine compartment. I am using a electrical fuel pump.

1.) Your fuel pump will thank you. 2.) Clamps will not be fighting pressure. 3.) Safer to have possible failure points out of engine bay. Colin

To keep crud from breaking your fuel pump. I have a filter between the tank and pump and another big hokin filter in front of the carbs - outside the engine compartment.

That's the second craziest thing I ever read. These carburated things run with 3 pounds of pressure.

Wow, I am really scoring points with you. I don't know crap about getting hydraulic valves to behave and I am spewing craziness about 3 psi fuel pressure. Don't know why all these air-cooled VWs burn down on the side of the road, but hey. Take a look at the taper of your average in-line plastic fuel filter with the stepped diameter that people will cram the heat-petrified hose over, and then watch them wrench down on the fuel clamp. The hose will squirt right off the filter under operating pressure and engine vibration, particularly when the hose is a little short and being asked to take a sharp turn between the filter and the carburetor. I say leave the filter out of the engine compartment and you think that's crazy. Watching the Challenger explode because of a slightly brittle rubber o-ring was pretty crazy too. Colin

On the pressure side you risk BURSTING the cheap plastic filters and you'd get gasoline all over the place. And there's those two additional hose connections that could work themselves loose easier with the help of that pressure.

AND, what's most important, you would add a considerable amount of WEIGHT in the fuel line between the pump and the carburator. (Filter full of gasoline). This added weight will put more stress on the fual hose fitting on top of the carb, and it's only a brass tube that's pressed into the aluminum carb top. They are known to come loose! The heavy filter will bounce around in there as you drive over bumps and whatever, and it keeps sending "tug" signals to the fitting. A simple hose won't.

Thanks Jan.

I will remove the filter and install before the pump.

But what if you have a metal fuel line going to the fuel-pump bolted to the pump?? I have secured the filter with a bind wire from one clamb to another under and above the filter. This makes sure the filter will not come loose from the rubber fuel line on the pressure side...

you put the filter in the hose between the metal line and the gas line coming out of the tunnel. right next to the transmission, below the car.

You still need to tie the filter down somehow, to take the weight and movement-caused shocks off the top hose.
