I have an 87 Trans Am that has the electric pump in tank and the mechanical pump on the block. If I do away with all the computer stuff can I go without the pump in the tank? Or can you run the pump in the tank with out the computer equipment?

 

Yes, and yes.

What you cannot do is run an external pump that is trying to pull gas through a non-working intank pump - it'll work for awhile, but eventually burn up your external pump.

I'm assuming your thinking of going non-computerized carb - why? Your computer carb is much much better than any other carb you can get, up until about 350 - 400hp, then you'd need a different carb. There really is nothing better than your stock carb setup - keep it if it functions and put any motor under it you like (under that hp).

 

I have a 305 now and will be building a 350. But it will only be built for around 300hp. So the best thing to do would just keep the computerized stock carb?

 

Yep - easiest cheapest best performance best mileage route you can go!
