Leaky fuel injectors after install problems

I replaced all my injectors for the first time on MY 4runner W/5VZFE engine. I bought remanufactured from RockAuto & followed my Chilton's manual closely and when I fired her up two leaked. I got one to quit as it was accessible and just removed, replaced, jiggled, and wiggled until it quit. Then I noticed another leaking on the driver's side under the manifold. I devised a tool to push back and forth in hopes I'd get lucky but no luck. I pours out of the top.

A couple questions;

1. Is there any way to check the injectors before putting the entire manifold back on to save hours of time?

2. Is there any gasket seal that might help stop this pouring out of gas?

3. Is it common to have problems with remanufactured vs. new injectors?

4. I was constantly worried about blowing myself up or starting an engine fire with all the gas yet I read another thread where a guy actually drove his home. Should I continue to be cautious or is a fire threat minimal. ( I shut the engine off after about 30' as the manifold starts heating up and I don't want the gas to ignite the gas.)

Any thoughts, reply would be appreciated.

Please help as I'm about fed up with this.

it would help if you filled out your signature so we know what you are working with.

4th gen has several versions

v6 2wd
v6 4wd
v8 2wd
v8 awd

in your case, v6 or v8 will suffice
 
The motor he stated he has is the third gen 3.4 isn't it? Maybe he posted in the wrong section.
 
So its leaking from either where it is inserted into the fuel rail, or at the bottom end where it inserts into the manifold.

Both ends should have some type of oring or insulator to seal it. check those, they do get damaged during installation.

Also, make sure the leaking ones are aligned into the ports on both the fuel rail and the manifold, if they are cocked to the side a bit they can leak.

If that's not it, then take it out and inspect it, could be a damaged injector body that is leaking?

You may have a local shop around that can test the injector, that way you'll know its the installation part, not the injector itself.
