R18: Fuel Filter "2008"

[john4o8]

i own a coupe r18, im going to change the fuel filter.
anyone know where its located?? please let me know thanx!

[SRT4H8R]

It's inside the tank man. I asked about it a couple weeks ago.
Our filter isn't as accessible as like an EK is.

Generally infollow the rule, "if it isn't broken don't fix it."

Would you say in this case to go ahead and replace the fuel pump so that yOu don't have to drop the fuel again in the future?

Well if u really want, u can change it. U don't have to drop the tank. Just remove the rear seat and u can access it from there.

If you do go a head and do it, I would recommend burning off as much gas as you safely can with out running outa gas. This way you have less chance of splashing gas around the inside of the car, this saving you smelling gas inside the car. A friend installed a bigger fuel pump for some reason and did it with a full tank, it splashed all over the place and smelt like gas in there for a good 6 months.

I have the HELM manual for the car and there is nothing in it to even suggest bothering with the fuel filter unless you have a damn good reason to mess with it. If you filled up the tank with apple juice and charcoal starter you might want to change it. Or maybe if you buy gas from a guy who sells it out of milk jugs, then it might be worth changing. I don't think it's worth fussing with unless you have a real reason to bother.

Maybe at 150k if you buy cheap gas, otherwise I wouldn't bother replacing at 40k unless you got nothing better to do.

I lold so hard when I read the intro

Ok so I'm confused.. if we never have to replace the fuel filter, then in my case what would be the cause of horrible gas mileage? i use 93 octane on my 08 r18. I dont rev hard all the time, tires are properly aired, i maintain it well every 3k miles it gets oil changed, i dont keep my car heavily weighed down the inside is regularly clean. I dont understand why I get maybe 170 miles out of a tank. and i fill up when my gas light comes on. any ideas guys? only thing i can come up with is its some of the mods i've done, but i thought better flowing engine would increase mpg not dramatically decrease it.

The R18 is tuned for 87 octane from the factory, not 93. That's Si territory.

Ok but wouldnt using higher octane increase horse power regardless?

[JDM498]

No,^

Using higher octane gas on a r18 will burn your spark plugs up faster and cause a hazing over them.Also no need to change fuel pump unless its not priming.

[Russell764]

Check ur battery amperage might be the reason, or spark plugs

ok thats good to know. So if i go from 93 oct to 87 oct on the next fill up would that clog something? or should i gradually go down in octane?

False. Near zero effect on the plugs.

1- 3k mile oil changes are not needed. Read your owners manual.

2- check air filter

3- if higher mileage maybe timing or valves need to be adjusted. Perhaps a tank of high quality fuel system cleaner.

[JDM498]

true/\

I would be glad to show you proof of this ryker .

And also additives are not recommended read your oem honda manual .
