Integra gsr guzzling gas... Very bad gas mileage.

[SMACKABEEZY]

So ive noticed that my car has been killing gas like a v8. So I filled it up $20 (half a tank) Drove 20 miles. Now the gas needle is sittin on a quarter tank left. Wtf?. Mods are dc headers, stock piping, stock intake geeddy evo 2 axleback. Idle is normal and no jumps. Shifting mostly @ 3k. 60 to 80mph freeway avg speed. This thing is killing me on gas help!!!!!!!

Leaking gas? Where could the leak be? No check engine lights btw. And I pump 91 chevron.

Make sure those copper washers on the fuel lines don't have any tiny particles on them. That's where I had my leak, s*** was killin my pockets until I found that leak.

Copper washer? Where do I find these at?

Fuel filter?? On the firewall. Like brass lines on top, there is copper washers in there. Thats where mine was leaking and i was getting about the same gas mileage as my 84 cutlass with a built 350 in it haha.
