I have a carbie 2.6 1988 Magna
On the fuel cap it says unleaded fuel only
I have been putting unleaded but just wondering any chance that cap could be off another car? And that I need to use LRP?

unleaded cap wont fit onto a leaded car. leaded car has a different filler (big hole) where as unleaded has the little one.

your car is after 1985, you need unleaded... 1985 TM was mostly leaded (like mine)

Thanks for that ;)
