Will it hold a vacuum after I release the handle?

Yes it will hold. It will only drop if you don’t have it attached right or there’s a vaccum leak

will this provide preasure also

It is supposed to..I bought one..it could not supply enough pressure to reverse bleed a atv brake system..or even supply enough vacuum... I returned it..hope this helps

Can it do positive pressure and pumping or does it only do vacuum?

Turning the dial on the nozzle or tip changes from vacuum to pressure. At least the one I purchased works like that. This looks to be the same one. I used mine for power 💪 steering after using it to vacuum all fluid and our out system I simply turned dial and filled system with new clean power 💪 steering fluid. Turning dial gives positive pressure and turning the opposite direction gives negative pressure (vacuum)
