It has been raining here for more than 2 weeks, so I have been working on the 124 in the garage. It has a few problems I have been trying to work out. Now that is has stopped raining, I may even try to start the car!
In the picture below you can see that I reverted to the stock air cleaner, added a fuel pressure regulator, a fuel pressure gauge, a float bowl vent hose for the carb and also a shiny new positive battery terminal.
You can stop here if you don't want to hear the details or explore the depths of my incompetence.
Stock air cleaner fun: The new DFEV carb came with a spiffy little chrome air cleaner, but it didn't allow for the oil breather hose or have a properly sized fitting for the vapor canister hose. I came to the point that I felt it best to revert and take those two issues out of my problem list. The original studs from the DSHA were too small for the DFEV mounting holes and the M6x.10-12mm bolts that came with the DFEV were too short to mount the much sturdier stock cleaner, so I got the properly sized M6x1.0 bolts in 25mm and 30mm lengths to to mount the cleaner. I am not sure why it took two different lengths, but it did. All was well till I realized I left off the "air cleaner retainer" bracket that goes on top of the thick rubber seal inside the air cleaner. Naturally, the holes in that retainer plate were too small for an M6 bolt. I drilled them out. I think I need to paint that air cleaner.
Fuel pressure fun: I put an electric fuel pump in last winter, but it seems to put out a bit too much pressure... maybe. I installed the fuel pressure gauge first to get an initial reading. It read about 4.5lbs, which is what the pump was rated at. The Weber carb wants between 2.5-3lbs if I am reading the Weber info correctly, so I added a Holley fuel pressure regulator between the pump and pressure gauge. The freakin' regulator bled gas from every fitting and gasket.. a lot of gas... not a little. The best part was as I fixed one leak it moved to another fitting. Fun stuff. The fuel pressure gauge reads just under 3lbs now that all the leaks are stopped. Note: Look how clean the inner wheel well is from all the gas running down it from the regulator.
Battery terminal fun: There car has stranded me twice with starter issues. Both times on Cars and Coffee days... weird. The last time, I was checking the battery connection and the positive cable came off in my hand. At first I thought I forgot to tighten the clamp, but looking in my hand I saw there was no clamp on the cable. It was still on the battery. I cut off the ends of the positive and brown wires and stripped back to clean wire before putting the new clamp on.
Bowl vent hose: Have you ever had one of those days where you installed a new carb and couldn't figure out what that 3/8" barb coming off the side was for? So you figure it must be the fuel return, since the old DHSA had a return? Then you drive it like that for many months before finding fuel running down the intake manifold and wondering why it isn't just going down the return line? I have had the exact experience. So that barb is a bowl vent that is supposed to go to the vapor canister... just in case you ever need to know. You can see a 3/8" snaking around the front of the battery and heading for the canister. The bowl vent points to the DS of the car, so I had to run the hose the long way around to prevent kinks.
One more interesting feature of this car. Note that the washer bag is held up by a metal shish-kabob skewer. The bag is not the right size, so I guess a PO came up with this solution.
