made a couple posts thus far but haven't go anywhere but its due to the nature of the problem.

So, now im asking, how exactly does the returnless fuel system work?

I am having problems with a RSX hydrolocking itself with fuel. (JRSC 7psi, 550cc's, and k-pro.) Ran fine for months, but all of a sudden it locked up the motor with gas, and now when you try and start it, it will lock up once the cylinders are full of fuel. (motor turns over just fine with no plugs or injectors)

Could it be bleeding the excess pressure back into the cyls? whats going on here, im lost. (Btw the injectors and comp tested out ok.)

 

doug of hondata, said many people are having problems with the 550cc's on the rsx, with kpro

its just the 550's for some odd reason, maybe try switching to 650'cc to see if it changes

 

Man thats funny he never mentioned anything about that. Maybe this is the car thats having problems. Never mentioned others, infact he insisted that it cant be his computer and thats about it.

 

iirc my friend mentioned it was the way the 550cc rc inejctors are spraying or somthing to that nature, check on clubrsx
