Sounds easy, and it is not hard . The newer faucets have shorter connection fittings tho . The connector may bottom on the retainer nut and not seal. So the fix is to flip over the retainer nuts, exposing a longer shaft for the inlets nuts.
Also , try to avoid stopping midway through the job , to use the toilet.
When I got done. The shine made me clean the stove, polish the bath fixtures, , clean all of the mirrors, wax the floor.
Have you pics of your install??

Sure
I hate drips .. So I also swapped the bathroom faucet to a single handle MOEN.
The OE faucet uses a old style .( kitchen) style of inlets. the inlet is also the retainer stud . The fitting are very close to the back of the sink and hard to get at. The offset plumbers pipe wrench would help .
Be sure to have new supply line gaskets.
My hot water is very hot . Having a 2 handle faucet requires turning both to get a warm flow. Lazy me wanted a single touch flow that works. At the races, I like to make as little of a mess as possible without slinging my hands all over . Now it works well .
FWIW the OE fixture is almost all brass. very nice but the seals leaked a tiny bit onto the backsplash .
This time I avoided using the toilet and flooding the bathroom .
20 min job= about 3 hrs.
