    mk4 c20let fuel return question

    ok fella's nearly finished my c20let conversion on my mk4 astra sport, i just have the fuel return to sort out. Now i know that i have to remove the fuel regulator from the tank which is relatively easy but how do i run the fuel return into the tank? i remember pepe used to have some good pictures of how he done it on his estate but those pics have disappeared. is it a good idea to run an external swirl pot or can i get away without one?

    thanks in advance for any reply's

    I need help on this one too mate. I have a ZLET conversion and i took the pressure regulator out the tank and the engine now floods and dies. So i need to run a fuel return from the passenger side of the fuel rail!!??

    IIRC this pipe must run back into a T or Y piece near the fuel filter. NOT into the tank. As i already have a return to the tank.

    Any help much appreciated. Can't release all the power using my 1.8 pump and regulator. And i have a Lambda error codes as the engine doesn't know why its not getting enough fuel!

    you need to run the pipe directly into the tank with zero resistance in the line else the fpr can't do it's job properly. What is the current retuurn line used for? That should be the one you are using

    Yeah sorry to hijack mate!!!

    But thought the problem sounded the same to me.


    The Z20LET has 2 return lines.

    One into the tank (i have) and so will you flatout. But the second runs back into the pipes after the tank i'm led to believe (someone will correct me if i'm wrong hopefully)

    For the C20LET though i'm not sure. I would think it's the same as the ZLET but i'd look at a calibra or cav setup to see how they run.

    i'd rather someone who has already done the conversion tell me exactly how its done rather than guess at it tho mate, pepe had some excellent picture showing how to do it but sadley his photobucket must be down


    also not meaning to be rude but i'd rather keep this thread for c20let only as it saves confusion between the two engine types

    true mate was only trying to help.

    I'd look at a Cavalier or Calibra setup and copy that. No guessing involved then
