fuelpump:
you COULD.... but you would be sucking thru your tiny stock TBI pump... and that kinda sucks. good chance that you cant pull enough fuel thru it.
a walbro is a direct replacement, i mean DIRECT REPLACEMENT, and it works great..... your other option is any replacement TPI pump... athough i would not reccomend a cheapie.
ive done the job countless times now on alot of cars... its never a enjoyable job, but it doesnt have to be too hard. if the exhaust isnt on the car, its downright easy.
speedo:
with a stock harness, you can wire it to the gauge... with the painless, look at the directions..
tach:
get a tach converter box off of ebay, search for "LS1 tach adapter"
it uses 4 wires:
tach in from ls1
tach out to gauge
power
ground.
throttle cable:
use a non TCS LS1 cable... the GM part number is :12565559
you may have to use a small spacer on the cable near the pedal to achieve WOT.. check this.

>i had to replace the gass tank for the second time on the car and i pulled the stock tbi pump and replaced the legnth of the pump with a pice of gas line . will it work ? the tanks are a pain!!!

you could use a aftermarket inline pump.. its not as efficent, not as quiet, and wont last as long.. and you'll have to find a place near the back of the motor to put it, but i'll work... not the ideal (or cheapest) solution, but it saves you the "work" of dropping the tank.
however, my blunt opinion of doing that on a 91 camaro is: "thats a hackjob way of doing it. if you're going to be lazy, then why bother?"

here are the ones on ebay i was thinking of...
http://stores.ebay.com/Baker-Electro...eNameZl2QQtZkm
well heres the story i baught a ls1 for a guy i no , the motor had 9500 miles on it , he slod the rear end and motor to me for $ 2100 wich is a steal cuz its fully assembeld it came with raidiator trans cooler, motor mounts wich didnt help me, stock air box, manifolds y pipe, inline fuel pump and relay, ecm . for 2100 i thought it was a good deal? any ways thats why i was going to use the in line pump cuz it cam with the motor? i dont want it to be a hack job alouth im not a pro at this but have a lil experience with cars. but the inline will work im just trying to save a few bucks cuz i already have the pump!
one more quick Q about the tach signal it say if the car had a different amount of cylinders ? the car had a 305 in it ? im not the best with electrical so thats why im asking

the 305 is a v8.... a standard "normal" tach signal would be 4 pulses per revolution... every time the distributor fires, it gives a pulse... the tach reads that and moves the needle.
the LS1 has no distributor.... so it doesnt make a "normal" tach signal.. but the PCM outputs a 2 pulse per revolution signal... like a 4cyl....
this box takes that "4cyl" 2 pulses and makes a "8cyl" 4 pulse signal... so your stock V8 tach can read it.

then it has a intank pump. you're probly looking at teh fuel filter then... common mistake, they do look kinda like inline fuel pumps.
not to keep jumping form topic to topic but i have so many Q i dont want to forget them! what r u using for a air filter set up? and do i need a fuel pressure regulator?just wanted to post these before i forgot dont need answer on them right away i want to figure out the fuel pump first

it does have a ground wire/strap... no positive connection.

if you do have a inline pump, its not stock..

yes you need the pressure regulated.... easiest and cheapest method is a corvette filter/regulator.... the regulator is built into the filter.... and because the filter is ment to be replaced, its cheap....
