crx hf fuel system same as the rest?

is the fuel system the same as say a dx or si? or is it weaker? will it be adequate for a b series?

Off the top of my head...the fuel tank is smaller (10.5, maybe 10.6?).
Maybe the lighter chassis will offset less fuel but I'll bet you have to fill up 40-50 miles sooner than a Si or DX.

I remember reading about a guy with a HF that put in a 25 gallon tank. Went forever between fill-ups.

Anyway, if you're worried about future plans...buy a fuel pressure gauge. They're relatively cheap(I got mine for under $50) and pretty easy to install(20 minutes, literally). This will be how you determine if the fuel system is delivering or not.
