I asked my mechanic to change all the fuel lines in my ‘74 A lfa. He left the odd sized one between the filter and the pump becaus e both were filter and pump were new and he assumed the line was too . I clamped it off with a vice grips to check the pump and this is what happened. It’s why you change every rubber part that touches fuel in a 45 year old car.

Like dissolves like. Even if it takes a couple decades

I assume he meant even things that don’t touch fuel like coolant hoses , belts, etc. , but yeah probably best not to use condoms of unknown origin either.

When I first got my 75' 1502 it reeked of gas. Like I had to drive with the windows open in the winter or I’d get dizzy. Turns out the original fuel line that BMW decided to run inside the car was still there and seeping away. Now there’s a steel line from tank to carbs run through the tunnel.

Yep! I just went thru this with my 56 Thunderbird. Luckily I only drove it to my storage unit 2 miles away and noticed gas pouring out from underneath it when I got out . I was able to clamp it and push it into the unit while I waited on a new line. Had I been going a further distance it would of pumped out all of the gas and/or caugh t on fire.
