Default Walbro GSL392 questions

I hope this isn't a retarded question, but would it be recommendable to leave the intank stock fuel pump and the walbro pump at the same time?

I would pressume that de-activating the stock pump would throw the PCM off, but wouldn't the Walbro choke when the stock pump isn't feeding enough fuel?

Also, what is the best placement for this on an F-Body? any pictures would be appreciated.

If you need more pump, replace the stock pump. Adding an inline with the stock pump gives marginal benefits.

Do it right the first time & replace the factory pump.

No doubt that is the way to go. I actually got this pump for a good price so I jumped on it without hesitating. My plan is to change the stock pump as well, however the price does not meet my budgeting right now for the in tank pump.

I'm just wondering if the inline pump with the stocker will have a negative effect.

I can eventually run 2 Walbros, right? the intank and the inline?
