3. "I ♥ turbo lag."

2. "I really wouldn't know what to do with another 75hp and of torque anyway."

1. "CIS: it's the future, I tell ya!"
#10 is serious because the 10% ethanol content in todays E10 gas is only going to go up. Our ______ president is as far from being a car guy as it gets so he doesn't care about what happens to older classic cars with this ______ gas we'll be getting in the future.

From what I've read the original o-rings in CIS fuel heads can handle E10 for a while now but it makes them rot away eventually. They say the ethanol content in gasoline is going to go up in the future and when it does the original o-rings in CIS fuel heads will swell up or disolve or just rot away inside the fuel heads making them unusable and needing a rebuild with modern o-rings to work again.
CIS Flowtech can do that for you or you can buy aftermarket USA made fuel head rebuild kits with modern o-rings on ebay and try doing it yourself.
