Anybody know where I can find the fuel system diagram for the 6th and 7th gen?? And also does anybody know how much it would be to put a return fuel line into a 7th gen and would you need to change the ecu becuase of that?

As far as cost, I can't help you there. More than likely you will need a piggyback fuel controller such as the ones .Greddy or APEXi makes.

hmm.....i know i read an article somewhere recently about this topic, that is, converting the EM Civic's fuel system from return-less to one with a return line. i think it had to do with an aftermarket company having to do this for their turbo for the car...hmm, it was a great read, i learned a lot, i'll try to find it.

Actually, it can't be done with a piggyback FMU....you would need to go standalone. Something like the AEM EMS.

ok, i found the article i was speaking of....it was in the Aug/Sept 2002 Honda Tuning mag, pg 76. read the whole article if you can, its about mostly the K20 engine series and mentions swapping them into the EM Civics (thats 7thgen Civic platform) and it also gives some useful info about the cars and fuel systems etc that i didnt know before...it was an interesting read.

i've scanned pics of the pages, i tried using our scanner for OCR but it sucked...these are readable anyway so

(NOTE: these are not terribly 56K friendly, but they had to be high-res so you could read them...if they take too long to download. just go pick up the magazine)
