Replaced Fuel Pressure Regulator on the Volvo 240 today.

The original fuel pressure regulator on my Volvo 240 wagon finally failed. I tested the vacuum on the hose between the FRP and the intake manifold. It was a little below specification. Also I did a test for fuel leakage in the vacuum hose. I fitted a piece of clear vinyl tubing in place of the original rubber vaccuum hose. In the photo here you can see the discoloration in the clear tubing made by the gasoline. This test was done over the duration of 1 week. The engine was running richer than normal. This is why.
The new FPR works perfectly and gives great performance. Better idle, transition to accelerate, and more power throughout the rpm range. It pulls stronger, enough to really feel it. Accelerates quicker in traffic and cruises smoother. I’m very pleased with it. Bought the Fuel Pressure Regulator at the local Autozone.

Replacement was easy and took about 15 minutes. I loosened the two 10mm bolts holding the FPR to the bracket. Then, using a flathead screwdriver, loosened the hose clamp to the fuel hose. Last step, I pulled the Fuel Pressure Regulator out of its plug in the fuel injector rail and the rubber fuel hose. Be sure to catch the small amount of gasoline that flows out from the FPR when disconnecting it. I used blue shop towelettes. Before starting the engine, after installing the new FPR, turn the key to activate the fuel pumps and prime the FPR. The key can now be turned to start.

New Headlights and Seats Swapped…yeah!

This past week I finally installed new headlights and swapped the driver/passenger seats.

The headlights are a great improvement over the old. They also have upgraded 9004 halogen bulbs, Sylvania Extras. Just need to fine adjust the aim of each side.

I swapped the seats to have better support on the driver side and adjustable lumbar support. Woo hoo! It was a tight fit but it works. I reworked the wires, springs and foam while the seats were out. Also added reinforcement pressboard underneath. Much more comfy. The passenger side seat now has front and rear height adjustment but no lumbar. It would be great if there were an adjustable seat belt height adjuster on the door pillars and maybe adjustable seat clip receptacles. Yeah, the small cubby in the center console e-brake area is blue, should be black. I’ll either paint it to match or buy a new one on e-bay or one of many volvo owners forums.
