I agree with you sous. I didnt buy the tank so I could go a long ways with out stopping, I bought it so I could buy when I wanted and where I want.

I hold a total of 95 gallons and on our last trip from TX to GA, we saw diesel prices for 2.60 to 3.30. I believe our avg purchase price was 2.80 over a 2000 mile trip.

Mine is also on a switch with a pump. We set a timer for 20 minutes per pump so I dont forget to leave it on....

As I have said before, mine is on a momentary switch and I usually will move fuel from the auxiliary tank to the main tank for about 5 miles at 65 MPH. That gives me about 1/4 tank of fuel back in the main tank. Having 1000 mile range with the camper attached is very nice indeed.

Back on the topic of the off topic thread...

The 6.2 is said to get 13-15 MPG's unloaded, so if the 7.3 gasoline engine does better than that, it would be up near the diesel 6.7 MPG's. Not sure what the 6.2 gets towing ~10K lbs though...

Yup. That $1000 a month in payments won't even get you a nice one bedroom apartment here on the Central Coast.

Are there any write-ups on adding that second fuel tank to pump while driving in to the main tank? That sounds like a worthy investment for my future towing of a 5'er!

I installed my tank back before I was doing write-ups and videos. Although, I did document the procedure fairly well in the thread below.

https://www.ford-trucks.com/forums/1...ne-almost.html

I also have the instructions from the company I bought the tank and parts from if you want me to send them to you shoot me a PM with your email address and I will send them over.

You are right, it is a very worthy investment and one of my favorites. Nearly 1000 miles of range with the camper in tow, nearly 1500 miles of range without the camper in tow. Stop when and where you want, instead of when you have to. We have drive cross country many times and the tank has paid for itself many times in ease of filling and choice of stops.

I used to have an engine similar to that - it was called a 460. Can you say "fuel hog"?

Yes sir! I think this is where the enthusiasts are upset because they feel that the 7.5L (460cui) should have been the new gasoline engine instead of a 7.3L.

I will be interested to see what the new technologies and advancements bring to an engine of this size and the intended purposes, but still think they should not be using the 7.3L size.

There will be very little to compare between a fifty year old design like the 460 and the new all aluminum 32 valve monster that will be forthcoming. For reference, compare the 225 HP 5.0 of 1993 to the 475 HP 5.0 of the new Bullitt.

I HIGHLY doubt it will be 32 valves being that it is a pushrod design.

Its not confirm that its going to be push rod or OHC. Some guy in the SVT forum claim it was a push rod design but who knows. If Ford desides to go push rod, its a backwards step, but I hope its a pushrod design simple and efficient.

From what I read, the pushrod design was chosen to make for the smallest, lightest package possible. 16 valves vs. 32 valves makes for a significantly narrower when you consider that the little extra width required for the 4 valve is expanded because of the twin bank, V configuration. My bet is 16 valves. Look at the GM LS motors; tiny envelope and very light for their power output...and really, the 2 valve, pushrod design is still pretty competitive as a truck motor; i.e. GM and RAM.

I HIGHLY doubt it will be an archaic pushrod engine. It's been what, eight years since Ford has come up with a pushrod engine?
