Fuel System Flush

Fuel System Flush
I have a 2012 MDX Tech with 48,000 miles. I use only top tier premium gas. The dealer says I should have the fuel system flushed. Is this really necessary?
Thanks!

Fuel system flush reminds me of the good old days with 2/4 bbl carburetors and they actually put lead in the gas. Those were the cheap crappy gas days you get from U Pump It.
I can see needing a fuel system flush if you park your car +12 months and it is not running well or there is condensation in the gas line (car won't start below freezing temps). You can add alcohol based additives to get water out of the tank and gas line.
I have +120,000 miles on my TSX and RDX. I use Sam's and Costco gas about 85% of the time. It is not part of routine maint, do we need to change out the fuel filter in X amount of time or mileage?

mrgold, I know the sedans (TL and TSX) have inaccessable fuel filters. (it's hidden in the gas tank)
so, the assumption there is that it should work for the life of the vehicle, especially if using premium fuels.
not to sure where they are on the SUV's, but knowing honda and their frugal penny pinching ways, I'm assuming its in the same spot

Flushing your fuel system is a relic from the 60's.

You can also do a "longer" cleaning with Redline SI-1 Fuel System Cleaner. It uses P.E.A rather than harsh detergents to clean the fuel system. It raises fuel octane by a few points (like 1 octane point) and it returns a MUCH higher fuel efficiency right after dumping it into a tank of gas.
I'd gain 2MPG on a tank with seafoam in my 760. I started using redline after I started having a lumpy idle on the V12 and was told I had carbon buildup on the valvetrain and needed to dish out 3K for walnut shell blasting. I ended up holding it off until 105K with the use of redline SI-1. Also I ended up needing less fuel pump sensors with the redline SI-1. The sensors' contacts would rust, went though 4 in the first 50K. After I started using redline at 50K, I only went though 2 until 105K.
Best place to buy redline is off amazon.com. I ordered a case and dump in a bottle every oil change in the gas tank. It's cheap insurance to keep the cars running until 500K.
