Fuel Pressure - Not rising?

[lachlan]

so we are officially going in circles and gone no where

i asked on the first page where vac line came from . he has also stated he put a boost gauge on it and it had signal

also the stock lines are fine .

also fkn lol at who ever drew on the picture and called the fuel filter the " charcoal canister /vent bottle "

your gauge up to the windscreen isnt getting squashed by the hood is it ? / how trust wprthy is the gauge and how readable is it

just looking at this from the PC instead of the phone, are you running the guage on the reg or has it been fitted in the car?

i see a line at the back of manifold in the middle which goes from black rubber to what looks like the white plastic which uses the brass olive & nut connect method?

i was asked to draw which way i think the system was plummbed

the arrows / writing was to say which line went to each item

Gauge in window was not sqaushed and is out of our workshop pressure tester kit so would hope it was trust worthy

ohk . well its goin to be something really left of centre then i think .

does fuel pressure drop below 43.5 by the correct amount of vacuum when car is cruising ? and rise to 43.5 (3 bar) when the boost gauge gets to 0 ? then not go any higher ?

yup thats right - if anything it may drop a tad on full boost? i need to do another few runs of testing and will try and video it

from what i can see you have it correct .

from filter teed off to the front of both rails and then the back teed intothe side of reg and then bottom of reg to return

like this except your rails are in parallel

I\'d go along the length of the vac line squeezing it, I have to wonder if it\'s been teed off the old line that the brake booster was on, the one that has the one-way valve buried in it inline.

[lachlan]

the brake booster line is like half inch . it couldnt be used in this aplication at all

Small update - Have since got another manifold made up and installed

this one is alot nicer and have all the vac ports up top for ease of access

the problem i\'m having at the moment is i can\'t rev over 6,000 RPM under load

if reving in neutral i can get over ... haven\'t put a fuel pressure gauge on yet as just wanted to make sure the car ran ok first...

Anyone ever had anything like this? when it stops at 6,000 RPM i still show 10psi boost

Coil leads/plugs etc all good? Gap set right and plugs not filthy?

[NTICEN]

coils are off my mates wrx as he upgraded and had been running fine on his car

ones i had taken off my had small cracks in them

plugs are nice and clean with correct gap
