What type of fuel system does a D17A2 have: returnless or return?

[rcaca0]

Hello,

I am in the process of a K series swap and I and doing a little bit of research. I noticed a few articles saying that the k series engine is a return less fuel system. What does that mean? What type do I have in my 2002 Civic Ex D17A2 motor? Looking at the manual for K series motor, it looks as if there are two lines going to the motor: a fuel feed line and a fuel vapor line. I am just planning on matching these lines in the swap, is there anything else I need to do?

Thanks again,
R

The fuel pressure regulator is located in the fuel pump assembly in that car...so there's not a return line.

Best K-series swap article for that car that I've found:

Just wondering, so my 2002 civic is a return less fuel system? Is this right?

Seems that way. I would look at the fuel rail. If there is only one gas line going into it, it's return-less. If it has two lines, it has a return to the tank.

For all intents and purposes in this discussion, it is returnless.
