Hey guys and gals, I've been through a lot of these posts and made quite a bit of progress with cancelling things out about this problem I have, long story short, I have air in my fuel system somewhere, revs were all over the place and ran rough as hell, bled the hand primer which didn't fix much.
Tonight I bled the fuel injector pump, started her up and she ran like a dream straight away, took it for a drive and it ran soo much better, perfectly for a while, after a few minutes started very minor twangs in the revs, nothing like what it's been doing recently, just very minor and gradually building slightly, am I right in saying this points to a slow air leak in a seal somewhere or could it be residual air that will escape over time?
I'm new to the fuel system stuff but handy on the tools and I just don't wana go forking out $$$ for things that ain't broke. Any suggestions to most likely or what makes sense MUCH appreciated.
So far the threads on the site suggest to me maybe fuel filter o-rings etc? I'm hoping it's on the fuel filter side of things anyway.
Cheers all!
