We put in a new pump and filter yesterday. To pre soak the filter at the end of install (without starting), I turned the key for five minutes, off for another five, and once more on for five.
Beside two good hose clamps, a good idea is to have a large plastic bowl and a vise grip ready just in case (we sure needed them), once the fuel starts running.
I put nothing but Chevron w. Techron into this car, but was surprised at the amount of silt (dirt) in the fuel that was collected. Afterwards we swapped the fuelpump relay with a spare I had and reset it.
In the junkyard, I took off a perfect working air sensor (throttle plate housing) from a 380SEL. My throttle plate has a tiny bend and sticks sometimes. Before I knew better, I had caused this myself by pushing the throttle plate down from the edge. I followed Jonathans advise, and left the unit for 24 hrs. immersed in a bucket of cleaner. It looks like new, with an easy moving and tight closing throttle plate.
Next we'll install the other housing, I have two extra O rings for the bottom of the fuel distributor. I could not find or get any info whether there is a separate gasket under the housing between the stamped surround and the rubber booth underneath.
Will a light coat of silicone do the job?
The plan is to properly connect the housing, and then remove the whole center part together, and tackle the intake manifold for new gaskets and the eight plenum rings. Jonathan's suggestion to use Elring, Wurth, or hylomar sealer will not be forgotten.
I can't find a torque chart on any of the manuals I have. Is there one online somewhere? I would like to know the correct torque values for the air intake manifold, and the air sensor housing (throttle plate) ?
Any other suggestions?
For some reson my files look a bit different from graftdesigns, not sure why.
