I need to get started on replacing my fuel system on the Cougar. I have collected all the parts, and am ready to go, except for two things-

1) Which side to run the new system on? I see where a lot of cars have switched to the passenger side. I am thinking about keeping on the drivers side, kind of to have a template to follow. My battery is still up front too, so not much room on the pass. side.

2) Where to put the regulator in the engine bay? Can you guys show me some pictures of how you have yours mounted?

I will be using a Holley Blue with the supplied regulator, along with braided line, if that helps.

One reason some of the racers run the fuel line up the passenger side is get all the weight ovdr to that side they can to offset the driver's weight. They put the battery, fuel pumps, etc on the right rear corner.

Also, most Holley's with center hung bowls, have the fuel inlet for the carbs on the passenger side. This saves a few feet of very pricey braided SS racing hose.

But, it really comes down to the preference of the car builder/owner as to which side you installed the fuel line.


No fast Fords at this time but one fine cruising 96 F350 CC DRW Power Strokin diesel.
And one rusty 64 Fairlane nick-named the Rust Bucket....And sometimes called the Money Pit...

I think the reason the factory ran the fuel line on the driver's side was because that's the side the mechanical fuel pump's on. This would be a mute point if you have an electric fuel pump.

I ran my fuel line (electric pump)on the passenger side because of the Holley's float bowl outlet which means less expensive fuel line to run and less restriction, more area to mount the regulator, and less clutter because of the things like the master cylinder, steering box, etc. that are on the driver's side.

Mine is also on the passenger side. It was also ran on the passenger side on my granada. We mounted the regulator off the shock tower. It made for a fairly straight shot to the carb that way.
