cam follower swaps....

[bellios]

Hi chaps,

just a quick one - was looking to inspect the condition of my cam follower yesterday seeing as i was bored and figured it could be due a change soon.

So starts off removing the fuse for the HPFP, ran the engine till it conked to get the pressure down, whipped the airbox off snapping everything as per usual, and then started on the HPFP. Reading some other guides, i followed the steps as applicable removing the solenoid cabling etc, breather pipe to the right of the pump. then depressurised pump further using the scroeder valve on the right hand side of the pump before removing this altogether with a 13mm. Having already bathed in vpower for about 15 mins, i was waiting for someone to walk round the corner with a ciggy hanging out there mouth, but this didnt happen.
 
I then moved onto removing the bottom 17mm main fuel line, and this is where i started hitting problems.

I cracked the nut off and started winding it down, but there still seemed to be a f*ck load of fuel in there (under pressure). I wound the nut back a bit and waited a good min or two for the pressure to come down, but it never did. So - to anyone whos done this, should iust plough on regardless, or have i missed something. Is there an in tank pump thats still getting pressure down the fuel line even though ive pulled the fuse for the hpfp?

Any help appreciated!

Battery disconnected and drivers door closed?

na door open and fuse pulled.
is the drivers door the primer for the in tank pump?Doh

Have you never heard your fuel pump when you open your door? Id just disconnect the battery to be safe.

i didnt here it prime to be honest, but ill give that a go. is the tank pump on the same circuit as the hpfp? would make sense if it wasnt and thats why its still running even if the fuse has been pulled.

I was just wondering if someone has done this before if it was normal to have a bit of pressure still remaining in the fuel line/normal to get a bit of a spill.
cheers bud!

I had only a little fuel drip out at the hpfp when I changed mine and I caught it in a rag. The fuel certainly didn't come out under any pressure at all.
All I did was push the Schrader valve to relieve fuel pressure-I didn't bother with pulling the fuse...I made sure I didn't open the driver's door though.

This is what I find strange with yours. I wonder if the fact that you ran the engine has something to do with it (I left my car for a day without running). Although the engine stalled because you pulled the fuse, it seems that there is still pressure in the line at the hpfp side...???

im gonna try again with the door shut - i think that was the error of my ways, although with the fuse pulled, i would have thought this would have knocked out the tank pump. ive always depressurised fuel systems by pulling the relay on previous cars, and the schraeder valve was totally flat. I cracked the 17mm and began winding it off and fuel started frothing out of the top of the banjo connection bubbling under pressure  and was still going after 45 seconds at which point i decided to abort lol.

thanks for all your input anyway - really appreciated and sure thatll be it 

[bellios]

yup.... it was because i left the door open haha 

had a moochy and all looks well - thanks again for all your help!

I left mine over night, kept drivers door shut, didn't pull any fuses and used the bleed screw on the HPFP and very little came out, what I did find strange was that I didn't have a banjo connector and I'm MY2005. Instead one rubber one metal, which I found odd by all accounts.

Anywho, glad you didn't end up in flames eh.

always a result not going up in smoke when messing around with fuel lol

glad it was a simple solution
