bensenova Posted January 26, 2015 Share Posted January 26, 2015 I'm not a starlet owner, have a suzuki 4wd samurai, mechanics connected a glanza engine, amazing performance However I have problems with the fuel line. He has connected the fuel regulator after the fuel pump. I hae been researching and as far as I understand the regulator should have been between the fuel rail and tank on the fuel return? Its a universal regulator, internet shows that the side line should be connected to the fuel rail and the bottem connector to the tank return. I've got the bottem connected to the fuel pump line and the side connected to the fuel rail ?!?!? Can anyone help me out please Quote Link to post Share on other sites
bensenova Posted January 26, 2015 Author Share Posted January 26, 2015 PS its a glanza turbo engine Quote Link to post Share on other sites
AdamB Posted January 26, 2015 Share Posted January 26, 2015 You are correct that it is normally placed on the return line back to the tank. However it does not really matter where it is placed, if being before the fuel rail this is called "dead heading" the fuel rail, and generally keeps the fuel colder which has its advantages.

bensenova Posted January 26, 2015 Author Share Posted January 26, 2015 Thanks AdamB, so I guess the only problem I have is that the in and out are incorrect. its a universal regulator, line in from side line out from bottem and vacume from side. Mechanic connected out to in and in to out. Kind of stutters now and again.. At least the position isnt wrong so it'll be a quick fix. Thanks again, releaved Quote Link to post Share on other sites
Duduglanza Posted January 27, 2015 Share Posted January 27, 2015 Regulator has to be after the fuel rail... its there to hold pressure on the injectors! Quote Link to post Share on other sites
bensenova Posted January 28, 2015 Author Share Posted January 28, 2015 The fuel pump sounds like its dying, I'm presuming its because the regulator has put to much strain on it being before the rail. Will be placing it after the fuel rail today hopefully I wont require a new fuel pump. Thanks for the reply Quote Link to post Share on other sites
AdamB Posted January 28, 2015 Share Posted January 28, 2015 What fuel pump are you using? Could always try the test where you disconnect the feed line into a bucket and measure it out after a minute then you will get your flow rate. Quote Link to post Share on other sites
bensenova Posted January 28, 2015 Author Share Posted January 28, 2015 I think its an Epman external.Will try the bucket test tomorrow and let you know the results Quote Link to post Share on other sites
