I am having a lack of power when I get to speeds around 60mph. I am not sure if its some blockage or not. I have a new fuel pump and it worked great for about a week now I can't get over a mile out of town. I am not sure should I take it back to the place who put the fuel pump on and demand a new one? Could it be something else? It seems to run fine until its under a load.

Its possible your old pump was not putting out sufficent fuel, and now the new pump makes it go rich? Check your float level.

It would have to be stinking rich to lose power at 60 mph, I would vote for losing fuel flow volume due to restrictions between pump and sock in tank caused by a dirty tank.

When car loses power do is pop through carburetor, and or get a big flat spot when accelerator is depressed at speed, or when climbing a hill?
