I have pretty much adopted my grandpas 68 F100. I don't know anything about its history, but i drive a several times a week to keep everything in order. I noticed a fuel leak coming from the accelerator pump. It is leaking pretty good.
A friend said he replaced his diaphrahm and it fixed his leak. Will I need to identify my exact carb before buy i a new diaphraham and check valve. If so, how do i identify it?
Yep the kits are designed to fit a wide variety of carbs. It's worth looking over some of the carb rebuilding videos and familiarize yourself with the kit instructions. A can of good carb cleaner and shop air to blow out the orifice and such. New power valve etc. Easy peasey.
The biggest mistake for a newbie is while putting it back together is not latching down the float retainer pin. A good way to know if you forgot or not is gas will come flooding out the top vent tube or cover vent hole.. No flooding gas your good to go.
They were the same diaphragm and cover gasket assembly up through 1974. Was Grandpa's truck sitting around unused since the newer oxygenated gas came out?

I dont know a lot about the truck, but if i had to guess i would say yes.

The old rubber diaphragms didn't blend well at all when the new gas came out. So plan on buying a current replacement fuel pump soon. As a Ford parts man then and now I wish I had a dollar for every carb kit and fuel pump I sold back then because of this. I'd be retired and sitting around on the beach sipping on an adult beverage with an umbrella in it with Bajafishnut at his place.
Thanks! Got it fixed, the old diaphragm are two slits in it causing it to leak, fixed in about 2 minutes.
Maybe i should start another post, but can i install a tachometer onto this 68 F100? 390/c6 Im not even sure how high this engine revs because i have never been in one with a tach.
Absolutely! Many of the aftermarket tachs are selectable for 4, 6, or 8 cylinders. They just need a ground connection to the coil at the negative terminal, a hot connection, etc.
A 6k tach is all you'll need as that engine will never see this high of rpm range as it is.
And a dash mounted vacuum gauge also is a good meter to have for milking out the gas mileage and keeping your engine in it's best working range.

Will a universal tach and vacuum gauge work, or should I try to be more specific (Im always skeptical if universal parts are actually universal). I would like to have them, but ill probably just conveniently mount them under the dash somehow to preserve the original interior.

Most tachs can be mount on the steering column.
Trouble with mounting at bottom of dash is you can't keep your eye on it.
