Ok guys. This question has been answered I'm sure, but after some searching and not finding exactly what I'm looking for, here it goes. I am doing a restoration of a 1987 Trans Am. The car originally had a carbed 305. I am installing a LT1 out of a 1994 Corvette. Is the main benifit of installing the in tank pump just cooling and being quiet or is there something else Im missing? If I go with an inline fuel pump, I wouldn't have to drop the tank and change as much of the fuel lines, correct? Or is it worth the trouble of droping the tank and starting from scratch? Thanks in advance for any help. I am currently painting the engine compartment and hope to put in the engine in the next week or so.

 

Dropping the tank isn't too bad if everything goes right, takes a while though.

The fact that it runs cooler in the tank will make it last longer. It might be more expensive too with an inline pump, i'm not sure. Then you'll have to modify your lines for fuel injection.

If you swap hard fuel lines from a fuel injected thirdgen you will probably need to swap the fuel rails from a f-body LT1 so the fuel line connections end up on the drivers side. Then you will need fuel lines to go from the hard fuel lines to the fuel rails.

I got my hard lines and sender unit from the salvage yard in utica,ne.

 

Like he said dropping the tank isn't bad. I was by myself in the garage when I did mine. I had never dropped a tank and it only took me 30-45 minutes my first time from the time I started to having the tank sitting on the ground.

I described it like this in a previous thread.

I put my jackstands on the frame rails in the back. You do not have to pull the rear end all the way out. Unbolt the shocks, panhard rod, torque arm, brake calipers and anyhing else that I forgot. Do not unbolt the control arms. Keep the rear end held up with a jack while you unbolt everything and wants its all off but the control arms just lower it down to the ground. It will be out of the way and the only thing left will be the 2 or 3 heat shields and then dropping the tank. once your done all you have to do is jack the rear end back up and start bolting things up. This is the easiest way to do it.

One thing I did regret. If you haven't started yet, wash the whole area around the tank. The buildup of dust and dirt is terrible. If I ever drop the tank again in my car, I will wash as much of that off as I can.
