Advice please

Wonderfully useful link!

I guess I am used to a fuel pump that clicks till it is up to pressure and then stops? This one does not seem to do that - I had it jury rigged up on my test bed with no OPSS in the circuit.

Will definitely wire in the OPSS when I install.

Is it normal for the pump to click all the time when it is energized but the engine is not drawing fuel?

PS - I guess checking the OPSS will tell me whether the oil pressure is below 6 lbs!

Yes. My understanding is that there is an internal bypass/relief that keeps the pressure from exceeding the nominal 2-3 PSI.

I did the coil/voltage measurements - coil resistance - 4 ohms. Voltage with a few rpm on - 14.5 Volts. Ratio = 3.625 so that is ok

Outstanding, rock solid electronic ignition system.

Got a mechanical OP gauge at NAPA - hooked it up

Wired the fuel pump through the OPSS

Turned on ignition and fuel pump - pump did not run (which was not surprise as an ohmmeter indicated the switch was open)

Started motor - OP went to 65 lbs-psi

Fuel pump started to run

Ran it for a few minutes and OP dropped slightly. Did not run for a long time as I have a jury rigged ABS "exhaust" pipe to get the exhaust away form the engine while I fiddle and letting ABS get too hot is not a good idea.

I am going to put this engine in my boat. I will need to order some parts from MMI (and THE MANUAL) so there will be a waiting period.

Things I am thinking to do while the engine is sitting in my shed and easy to work on

1) Flush - acid flush - flush sequence
2) Oil change
3) plugs, rotor and cap
4) swap out the water pump
5) change outboard fuel filter

Any other suggestions?

With gratitude,

Peter

Paint? MMI sells original colored paint for the A4.

Check/adjust the valve clearances. Vastly easier out of the boat.
