the swap is possible u just need a ls1 style filler neck.. and you should be good to go..

 

And the thread is revived from the dead.......

 

i seen that.. so i figured i'd post

 

Wouldn't the ls1 style filler neck be on the ls1 tank?

 

Very possible. My buddy did it on his TA. Dont know the details though, sorry.

 

Their filler neck is a rubber hose.. and if you get the tank it might not be connected to it.. thats the only reason i said somthing..

 

I'm looing at this and I am gonna try to just add the fuel return line to the LS1s tank pump housing assembly, It looks very doable.

 

If it is just the fuel return that is the problem, that is simple. Cut a 1" piece of pipe about 1/4" id and weld it to the pump assembly after a hole is drilled. Are the dimensions where the tank straps go the same?

 

Well the connections are different as well, but easy to work around.

 

Oh yeah, the part that the straps go around is identical.

 

so are there any downsides to the swap? you need the tank, the filler neck, and i guess the different fuel pump? and fab some connection points.


sounds so tempting...until i look at the bills sitting on my floor

 

Electrical connections or fuel? Will an LT1 sending unit assy. fit in the LS1 tank?

 

Both, the elec plug is different and the fuel lines connections are in a different spot and a different type.

 

Any pics that you can post?

 

revive the dead..who did it and how much work what year ls1 tank did you use?
and can you use a ls1 tank with the lt1 fuel pump assembely, sending unit, everything from the lines outside the tank to the pump drop it into the ls1 tank or is the opening differant?
