If you go external,just be sure you install an SE fuel tank or a baffle box around the fuel pickup, inside a non SE tank.Below 1/3 full the fuel will slosh away from the pickup during lefthand turns.Fuel injectors use pump pressure to fire,and will stop injecting the instant fuel pressure is lost,unlike a low pressure carb setup which can pass some bubbles with no issue since the carb has its own supply of fuel in the float bowl.
If you happen to be boosting at the time,the lean out condition caused by loss of fuel pressure can blow the motor.Even if your not boosting,slamming your head into the steering wheel when the car stops accelerating,is no fun either.

You don't need baffles or anything if your tank has a drain plug. Just plug the stock fuel sump and put a fitting in the drain plug. The stock pickup is just enough to support a blowthrough nikki with a stock ported motor. I know the drain plug is good for at least a weber48 with a large streerport. And that's with the stock hard lines. I never run under 1/3 tank anyway, and I wouldn't suggest doing it with whatever tank you have unless it's a fuel cell.

It's external. Don't bother trying to put an internal in, it's not worth the effort. Just either put in a new pickup in the tank or do what I said with the drain plug.

how do you install a baffle box around the fuel pick up? What did you do for your setup? My car started life out as a GSL so my tank is different then a non se tank right?.
I was thinking of getting my tank sumped since its fairly inexpensive.

this is what I did: use a pre-pump (low pressure, high flow) to pump fuel into a swirlpotk (example: http://www.tweakit.net/shop/product_...roducts_id=124 ), then use a high volume EFI pump (as luiml73 put it: better safe then sorry!) to feed the engine. I used a SX pump (I believe a 18201 aswell) but just make sure it's a good one. This is a perfectly safe route. But if you have a GSL-SE tank (mind you: it WON'T fit an 1982 without modifications! This is due to the spare wheel carrier being different: the 84-85 models have "fake" spares, to use a larger fuel tank) you can use that, it's baffled and doesn't require a anti-surgetank.
DON''T use a stock gastank without a surgetank: the pump should never suck air, with an EFI engine this will lead to a bad running engine.
Also note you'll need bigger fuel lines. And a good return line.

I am curious about this as well. I want to go with a fuel cell. That would have a good sponge type thing in the cell that keeps the fuel from sloshing around. I want to run an externam MSD pump. DOes that seem like a decent idea?

I have the 16 gallon cell from Summit with safety foam and a GM guage sender that I've modded to output a resistance reading my Mazda guage can use. It's simple; you cut a trace or two on the circuit board of the sender and add a jumper which reverses the resistance curve. I had to add a 10 ohm resistor to the S terminal to get a correct empty reading (the full reading isn't as important as the empty reading, if you know what I mean).
I've also installed a Walbro 255 with a Fram G3 in front of it. We all know Fram's oil filters suck, but people here have said their fuel filters are decent.

Im new to the group, so please forgive me if i am asking repeated questions. I have an FB with the 12A, fuel pump gave out. I want to replace it with the Carter CRT-P4594 fuel pump and the Holley HLY-12-804 F.P.R. It has a Mikuni carb. If anyone has performed this upgrade, I am in need of some pretty detailed instructions for this mod.
Thanks.
Thanks.

It's best to mount the Carter with the motor at the bottom and the fuel fittings at the top. I had one connected to my fuel cell for a carb setup before I got the Walbro for an EFI setup. The Carter worked fine when it was in there and made a lot of noise. Yes, Carters are loud fuel pumps. I'd recommend rubber standoffs or something.
