bleed valve to blame??
Turbo Mini Forums

You never know Ben, the louder pump noise could be a sign that it's now operating properly as mine has been as loud as you describe since mid 2008 !

Tx me if you wanna pop over for the pump, I'll take you for a spin in the van.

nice one rich ill you drop you a text about heading over...def wouldnt mind getting out in the mighty lime green machine :)

we'll get this thing working properly if it kills me lol

No they try and kill you when there running well

is there a filter before the pump ben ? could be blocked .

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

right heres the update so far :)
checked my valve clreances and aside form a litle tweak they were fine..on the ups side though the spark plugs all looked good, with only the 2 nearest the flywheel lookin a tiny bit rich.
after poking around near the fuel tank to see if there was an inline filter i noticed there was NO earth wire to the fuel pump..which was umm nice to see , so rectified that.
ive just been out and tested the actuator by pulling he hose fro mthe actuator off the bleed valve and bodging the pump onto the pipe and the actuator rod literally starst to move as i push the pump a tiny bit , then if i push o nthe pump a decent amoutn more and the rod fully extends without the gauge so much as even twitching..i took the pump off put my finger over the end and pumped it and it moved straight away so i know the gauge is working.

not really sure what this means ? if the actuator is operating under extremely low pressure or the pump is just gash but id have thought even with the connection not being compeltley air tight itd have atleast registered some kind of pressure

just to add i just went out and did the test again as i found an old wheel valve..and the rod still moved pretty much as soon as i pushed the pump but if ipump the footpump a few times to try and get some pressure reading on the gauge i can JUSt about get it to read approx 5psi with the rod being fully extended, and the rod starts going back in at about umm 3psi ish...but as i say seems to not need the 5psi reading for it to be fully extended.

i hope this makes any kind of sense

sounds like a stock 3.5 psi metro diaphragm ben .

so everything sounds about right with the actuator then? at least thats one more thing i can tick off the list ...just got my 8mm t-peice in the post, thansk ebay..so will be checking fuel pressure is rasing properly as soon as i grab a new peice of fuel pipe fro mthe local parts supplier :)

id put a stronger one in there for some stability ,something like a 7 psi one ?

can you change the diaphrams on a standard actuator or will i need to uprate it for say an avobar item ? i guess it wouldnt hurt either way, to cope with future mods

i think there are some stock t3 ones that are higher ...maybe save some money getting one 2nd hand ?

yeh ill have to have a look for some 2nd hand ones, a new ones about £85 from avonbar and after the wideband purchase could do without another £80 killing my pockets :)

are the cosworth t3 actuators higher??

thanks richard ..incredibly helpfull info as always..ill keep hunting for a decent upgrade.. just the fuel pressure test to do...after that tho im stumped haha
