i undo it from there, just make sure u have 2 spanners, 1 to hold the line so it doesn't twist and one to undo...

but dont do it with just 1 spanner, u could bend / twist the hard line..

That was the way I did it the first time, the rubber line twisted so much it ripped!!! Much safer to get it at the other end.
 
lol the mechanic ended up doing it, didnt end up ripping the line..too much :p also got a sard adjustable fuel reg put in at the same time
 
this topic is a bit old but i'm gonna buy a gss342. have you guys been running these without fuel pressure regulators?
 
$145 + $11 postage :D the gss342 should be more than enough on 1.5bar.
i'm more concerned about the car running too rich cos i've already got an eprom blowing quite a bit of black smoke.. but i don't want to unecessarily spend money on a regulator so i can buy my ebc.
 
hey guys a word of word of warning regarding walbro fuel pumps

i recently upgraded mine in the evo 3 and when we did it we changed the efi line from the top of the pump to the bottom of the cover as pictured above.

the walbro pumps purchased from a.s.s. (this is the buisness initials as i will not name them) do not come with this fuel line

this lasted for a day before the efi line swelled and the webbing inside came away and the line popped.
normal efi line will not do

3 replacment lines where used all suffered the same fate. you must replace this line with fuel line that is suitable for being submerged.
NOT fuel resistant line.
both the blue shit and the red shit that most places sell is not suitable.
stainless braided line is also no good as it is to small a line to secure properly

do not listen when some one tells you that all efi line is the same and that there is only 2 types of fuel line high and low pressure. they are wrong.

this can lead to a engine failure because it will happen when you are up it for the rent then sudenly you will have no fuel pressure or flow massive lean out.

i am not bagging the pump. the pumps are great after i had this issue sorted the car hauled ass so much harder in the top end
just a $2.00 peice of line can cause much heart ache

i'm running a sard adjustable fuel reg because the car pretty much flooded with the bigger fuel pump. it's great having one, and are quite affordable these days
 
.

has any body had trouble with the gss342 filters breaking up?

i put one in my skyline and was very worried about it failing

so i used the original
