2 different problems... 4x4/ coolant

Alright bought a 1988 f250 4x4 last week already had a new tank and fuel pump put in it.. Alright when I put it in 4H I want to lung forward and bounce up and down like it's trying to go faster but won't... 4L I don't think does it because it's such a low gear...
Now for my second problem coolant is coming from the top of the water pump a lil inch and half hose going from the intake to the water pump.. It's a 460 efi.. And does fine setting there idling but hit the gas and starts to over heat..

Are your tires the same size front and rear? And replace the hose if it's leaking.

Your 4x4 issue is most likely either different tire sizes on the front vs the rear, or different gear ratios in the front axle vs the rear. Read the tags on both axles and post the results if you can't understand them by yourself. Note that you'll likely need to clean the tags with a scraper or wire brush to be able to read the info stamped into them.

For your cooling issue, replace the failing hose immediately and that should solve the problem

You know you're not supposed to use 4wd on dry solid surfaces, right?
Read the warnings on the top of the drivers sun visor.

Making a turn in 4wd on dry pavement will always bind up the driveline and can lead to shaft or transfer case failure.

13 psi.

4wd on gravel is fine.
I'm wondering if you have a torn transmission mount or something.

Get a 195* thermostat.
Your fuel injection will always be compensating for running too cold otherwise.

Carb's aren't 'smart' enough to know better.

Usually when it's sticking out like that I just cut a screwdriver slot with a die grinder.

If it is rusted in, that's a different story...
