MPG Gone Crazy

Just wondering if anyone has an idea of what I'm dealing with my 74 f250 360 4spd is throw the loop at me
The previous tank and many before have bin getting me 12/13Mpg
but the past 2 tanks I've put in I'm looking at close to 9 mpg but I'm useing the same gas same driving route same speed etc I've done nothing different but what could be cause such a dramatic change in mpg?
I have not a clue but need to get this sorted out because this is my daily work truck and I drive 90km+day and I really don't want to start having to take my new truck onto job sites that's forsure

Have you noticed if it's driving any different? I'd check to make sure the brakes aren't sticking.

It doesn't seem to drive any different, but I'll check it out
another off topic question I have would be what are the casing numbers fir a t18 trans? or how can I identify a t18 I think that's what's in my 74 but not sure also looking for fluid compacity, brings me to yet another Q haha how do I find what rear end is in my truck? 74 2wd maybe Danna 60?
