1987 Ford F250 - 25mpg hwy or bust

One easy way to delete the belt driven vacuum pump and still keep your vac system is install an electric vacuum pump with a small vacuum tank up under the truck along the frame rail some where.

There is a lot of room under these trucks and even more so if you can let stuff hang down a little, but I think you can only do that as long as you don't have to worry about deep snow or off road mud pits tearing stuff out from under your truck.

The hydroboost system installs in place of the vac booster, provides about half again the braking power of the stock vacuum booster, and only requires one new hose from the PS pump that's already running all the time, even when you're not steering.

I have hydro boost, and it looks like a pretty big commitment of time and money to go from a vacuum brake booster to a hydro boost especially for no MPG benefit when you are trying to gain MPGs.

It's not. I've done the conversion about 30 times now, it takes less than a couple hours. I was in the process of doing it on my F250 when I got my Chevy 2500HD and scrapped the F250 in lieu of doing $1000 worth of body work on it.

...but I did pull the 7.3 from it.

Truck is back up and running. And now the fun starts!

I've got a couple more maintenance things to do before I can start actual modding, things like tires, but I'm looking forward to seeing how this goes. Just started a new job, so I should be able to keep it full of fuel regularly so I can get consistent mileage readings. I'm gonna fill it up when I get my next paycheck, and start keeping track from there. I plan to buy a notebook to keep in the truck specifically for recording mileage.

Even if you can't do a full fill up you can log the number of miles driven and gallons added in your book then total it all up next time you fill up.

Those side visors are popular on TDI's, but I see a lot of shocked comments about how much of a ht the fuel economy takes. It's a lot more than 0.1 mpg on the highway.

Finally got my first full tank the other night. Doing my regular drive to work with a few errands here and there, will fill up this coming weekend when I get paid, see where I'm at for a baseline.

On a baseline, I seem to be getting around 15mpg. Most of my driving is small town/short hwy. Now for the improvements to start XD
