[WTA] what is this box ? found on viva 850cc engine bay

[navz]

I dunno how to explain well so i include pictures for my question..

This is the box that i mention..

the red round mark is the join with red round upper picture.

thx...im guessing this is oem fuel regulator..but im not sure..hope anyone here can share with me..thx

 

[xtremeleo]

its the fuel vapour container, when it has contained enough pressure in the canister, it will channel the vapour into the throttle for combustion. a method to further save fuel

 

[trojan]

in automotive they called it carbon/charcoal canister....the function just like xtremeleo explained... :)

 

[navz]

sifu... can i disable it and take it out..replace with adjustable fuel regulator..

 

[xtremeleo]

DO NOT take it out, u can simply add an adjustable fuel pressure regulator witout taking the unit out sir. err, what have u done dat makes u think u need an APFR anyway?

 

[navz]

sry do u mean canister = fuel tank ?

currently..i already install afpr(for turbo purpose)..they performance shop kinda disable it already..but the vacumm hose still attach at the box[fuel vapour container]..they let the hose to the fuel tank not connected to the fuel tank[same like the 4th picture i uploaded..because..they use 5th picture i marked to do the afpr return line..they take out this thing(pls see below picture) from fuel tank and do the return line there..cuz viva dont have return line(they also modify my fuel rail in order to install afpr.and i use it for 5 month..1 day..my afpr become like this(pls watch below video)..i asked at zth forum before this..all said its fuel pump problem..i already change..it wasnt solve..so i just bot my car..so now i just feeling not ok with my afpr reading like that..so i tot disable this box MAYBE solve my problem..

plus : before this..when i want to fill fuel in my tank..when i open the fuel cap..i feel some pressure when i open it..now there is no more pressure when i open the fuel cap

ps: now i totally diy my car since i bot myself..never send to any shop anymore..

[xtremeleo]

disabling the box (box=canister=container, canister isnt fuel tank fyi) wud not solve ur problem sir, are u still using the original ecu? have u rewired the power supply to the pump? if u havent for both, please pm for more detail, tq sir

 

[tks]

what afpr are u using...?

 

[navz]

im using works fpr..already send the fpr for waranty..got brand new 1 but still the same...meter also changed..still the same..

xtreameleo ugpm

 

[xtremeleo]

as my reply for ur pm, its not a pump issue, nor it is an issue with the fpr sir

 

[navz]

true..already change pump..and uninstall the black box..still fpr reading the same..omg

 

[snoop-pie]

if im not mistaken, viva, kelisa, myvi have no original fpr, there's is no return line. so there must be a bleed valve inside the fuel tank mounted near the pump. when u want to rise up the pressure by tightening your WORK fpr, the xtra pressure will bleed back into the tank. u need to disable the bleed valve 1st( IF U HAVENT DONE THAT) just my 2 cent

what he said above is correct,need to do a T,one hose is from the fuel pump,the other one to the fuel fail and the other one for fuel return to the tank.
charcoal canister wouldnt do any harm as ive took it of from my sr20det.just menyemak in the engine bay.
