Increased Fuel Economy and Power for a 3FE Powered Toyota Land Cruiser?
Brandon over at olympiafj60.net mentioned to me on the Whiskey Dick trip about a thread over on ih8mud.com in the 60-series forum on an adjustment that can be made to the Toyota Land Cruiser 3FE engines. There happens to be some type of fuel regulator on the fuel rail near the firewall that be adjusted. People are reporting increased power and even better yet, increased fuel ecomony.
You can see the thread at What the deuce is this thing?.
Well I went ahead and popped the plastic cap off and tightened the screw a couple of turns. Initial impressions while driving around my house seemed to be an increase in low end torque (a very unscientific approach).
I now need to take a test run over Snoqualmie Pass to check against my baseline mpg of 13.4 when traveling from Federal Way to Ellensburg, Washington. Hopefully, I’ll have a little more power on the climb to the summit. When I have the data, I’ll report it back here.
Thanks Brandon for the tip.

Some preliminary information after my first road trip after making this adjustment. First, like I mentioned above, my Land Cruiser feels like it has more low-end torque. It seems to have a little better power on the top end. For instance, the few times I climbed the Vantage hill (westbound) on I-90, the best speed I could manage was about 45 mph. This past weekend, I was able to maintain 55 mph all the way up the 10 mile grade. Of course I had my foot to the floor in third gear (maybe the 80+ mph run across the Columbia River bridge helped carry some momentum up the hill). As far as fuel mileage, well on this 500+ mile trip, fuel mileage really sucked (literally). It could be that I was pushing the little 3FE hard the entire trip, plus I had an extra 200 pound person and gear along for the ride. More tests to follow.
