Vapor Lock????

I have a 1995 dodge Ram 1500 4x4 (fuel injected). After driving the open road for a good amount of time, all of a sudden I loose all power. Engine does not stall but it runs very rough w/ no power at all!

After sitting on side of road for a period of time (cools down) it starts running just fine again. Some suggest vapor lock. Anyone experience similar trouble? What might be remedy?

Oh, this happened with the old engine as well as the new engine that was installed about a year ago.

Greetings Mark welcome to the Forum.

if you really think it's a Vapor Lock, you should re-route your Fuel Lines away from the Engine. A couple more feet of line won't matter on the Pressure.

I've seen them insulated too. A length of Water Hose split down the middle, and placed over the Line, as it ran nearer to the Exhaust.

Might try that.

Have a good Day !

I had the same trouble just yesterday as I drove my 1998 Silverado through the 100 + degree Texas heat. At road speed, the engine began cutting out, losing power, and I had to pull over and wait for everything to cool down (20 minutes or so), start up and go again for 20 miles, then same thing again.

I remembered this was the same symptoms I had years ago before I finally replaced the In-tank high pressure fuel pump. I suffered with this condition for years before the pump finally got completely shot.

The bottom line....This only happens only really hot days and is caused by a combination of poor quality, highly volatile fuel and a pump that is on the way out, and not working at 100%.

The right fix: replace fuel pump
The quick fix (and what saved me yesterday):
simply add transmission fluid to your fuel (approx 1 cup per tank of fuel) this adds "body" to the gasoline and reduced the volatility. That's the only way I can describe it but it works.
