Due to the character limit per post I split the article into two sections; support devices and injection pumps
I added details about injection timing.
I added sections on ALDA, ELR and rack position sensor.
The M-Pump sections have been redesigned to conform with the MW pump guide style to make them easier to read/follow when translated to non-english languages.

Default Injection Pump Banjo Bolt

Hey ForcedInduction,

I got my banjo bolt out of my pump to attempt to check the length of my spring. I cannot for the life of me figure out how to get the spring out of the bolt. I see a circular 'bearing' looking piece in the head of the bolt. Is this what I need to remove to get the spring out ? ? ? THANKS IN ADVANCE ! ! ! ! please help

These are pics of my banjo bolt. I can see the spring through the small access hole. I posted another pic of the top of the bolt where the ball bearing piece is.

Your type is sealed and non-adjustable.

Only the type with a screw cap can be adjusted.

Default adjustable banjo bolt

thank you so much, I read through pages of threads but did not see anything about a non adjustable. If I am concernced about the wear of this part, can I replace it with a new non-adjustable or a new adjustable one ? Is there a better choice ? I have found the exact one I have on the web for $30.

$30 is high for such a small, simple part.

If the engine runs well, don't worry about it.

Default performance

Some days my car runs very well, others it seems to lag a little bit. I have changed all the fuel filter, removed the fuel tank and cleaned. Also cleaned the screen in the tank. Any idea what would cause an intermittent problem like this ?

If you have the old style screw-down primer pump, replace it with the updated spring return primer.
Clean the check valves in the lift pump. The inlet valve is below the fuel inlet side. The outlet valve is under the delivery hose fitting.
Do it with less than 1/4 tank and park nose up a hill or on a curb, otherwise you will lose a LOT of fuel through the lines.

do you work of 300td's?

looking at one outside of denver, owner says it needs an ip, but only has 125k...hmmmm.

i live in gunnison...looking to make the change from a c900t saab.

i suspect fuel filter/tank screen, but can't find enough information on changing the ip to decide if i want to take on this new challenge. doing the t-belt on my audi a6 2.7 wasn't bad, but don't know about doing the ip on the 603. i don't think that there is any shop here in town that i'd trust to work on any of my cars

let me know.
