I am giving my carb an overhaul it is a 34 dgas on a 2.5 ford V6.This has gone ok and i am ready to put it back.My problem is connecting the fuel line back up and the return to tank.One of the brass fittings into the carb has a small bore to it whilst the other has a larger one and i cant remember which way round they go. Thanks in advance to anyone who can help. If you need any more info please bear with me as am on 12 hr nights tonight so prob wont get back to you till morn
