Fuel Leak from Civic EG B18

[tnguyen]

I know roughly because when i fill up full (until it clicks) then it leaks until it reads half on my gauge. Then when it's reading low i fill up 25-30L (abit over half on the gauge) and it doesn't leak. And the tank is from a dc2 vtiR so im assuming its a 50L tank.

I reckon because the 2 way valve for vacuum is on the middle of the fuel tank, that's why u are not losing fuel.
So again check the vaccum lines and return line. Tell us what will happen

No worries will get back to you guys soon

I'd say it's the line... hmetro knows his shiznit!

Still leaking fuel. i've checked all three lines and they're all connected properly and used another dc2 vtiR to confirm but still leaks fuel -.-

Have u check the three line in the engine bay or under the fuel tank ?

I'm not sure why no one suggested changing all the fuel lines ?

You do realise that EFi fuel pressure is like 10 times carby pressure ?

Change your fuel lines asap.

Get rid of the charcoal cannister while you're at it Haha.. jk... But it does clear up a lot of mess.

thanks tiksie, i'll try source myself some dc2 lines, do you know if dc2 fuel lines fit eg or is it a bit longer?

[hmetro24]

Are they using high pressure Hoses for fuel feed and return. or just normal hoses

[tnguyen]

They are using fuel line rubber hoses - has braided/threaded lines within the rubber

Hey guys just replaced and switched the return/vacuum hoses and NO MORE LEAKS so far! Cheers for the help! But only problem now is when i fill up full on my dash the lever only goes to 3/4 of the way and not to the "F" indicator. I believe my float in my tank is playing up, but how do i access it/replace it?

That's mean the return/ vaccum were connected wrong as i said.
you can access the fuel float under the rear seat, you got couple of nuts.
this is the fuel tank,
