Mounting fuel filter
Is it acceptable to mount a canister style fuel filter in the engine compartment?
I want to move it from under the car off the frame to clean up the look from behind my car.
I was wondering if it's ok to put it on the fire wall with a heat shield around it?

Re: Mounting fuel filter

Re: Mounting fuel filter
Heat is an issue as well as engine parts exiting are the only thing to be concerned about hitting it or lines would be my only concern.

Re: Mounting fuel filter
You want the fuel filter at the back of the car, mounted/plumbed before the electric fuel pump on a street car.
Get a smaller body size fuel filter. The common $10 OEM type inline paper element fuel filters
flow HUGE volume. That huge body fuel filter is mostly show hype.
It's pretty looking but not better.
Get a suitable normal good OEM style inline fuel filter and flow test it in your on car fuel system on your car and see. Spend $10 and replace it once a year.

Re: Mounting fuel filter
If you end up at the track then you will probably be bounced in tech. No fuel system or components to be mounted on firewall.
Re: Mounting fuel filter
Every stock fox body mustang at the track should be bounced in tech too I guess? The factory fuel supply and return lines run across the firewall and into the back of the engine to the fuel rails.

Re: Mounting fuel filter
Most race Tech inspections frown on pressurized fuel containers due to the possibility of fires, and that extends down to autocross. The single exception is an all-factory setup and you may have to document that for some inspectors. Regardless of where an actual filter is mounted, it should be BEFORE the fuel pump so you don't have a container of gas at 45+ psi (or even 6 psi with a carb). Those are more properly called "bombs".
Re: Mounting fuel filter
The fuel filter should be after the pump.
'Never use any kind of filter-other than a simple screen- on the suction side of a fuel pump.' From the original Holley book written by Holley engineers.

Re: Mounting fuel filter
100 micron on the inlet side of the fuel pump, 10-40 micron on the outlet side of the fuel pump depending on whether efi or carb.

Re: Mounting fuel filter
This is false and it makes no sense... You want the fuel filter before a electric pump to keep dirt out of the pump.Geoff2 wrote:The fuel filter should be after the pump.

The filter does not restrict flow at all. You read too much.
