If I remember I cut the filler pipe and made the rubber hose fit.

The reason the replacement sender doesn't have a "Low fuel sender" is, from my understanding the aftermarket doesn't make one. And any that are out there are just old units or "cobbled" up units with parts from who knows where.

The cougar tank is the same as the Mustang. On the early cougars 67-68 the fuel fill is in the same place as a Mustang, except the license plate covers it. It's between the huge long tail lamps.

Still sounds like a very good project, if the extra fuel means that much to you. I don't really care that much for more fuel. When I had my 68 FB Mustang I drove it to Atlanta, GA to a large Mustang show. Around 400 miles one way. Stopped every 100 miles for gas. Small tank, 9-10 mpg. Plus, I needed to stop. Believe me, these old cars are NOTHING like driving their modern brethren of today. I love to drive them around town and on short hops.....but several hundred miles on the road....just not as much fun.

Take care, hope that helps...
