Default What to use best?

Hee guys,
Soon I am going to the weldingshop(machine fabricator) to have them make me a custom fueltank.
If I can choose, what should I choose for and why?
A full stainless tank with baffles
or a Aluminuim tank with baffles
Do you guys recommand no baffles but racing foam?

I will be using a 2000 LS1 fuel pump with regulator and sender.
Can I use a y-block mounted on the tank or on the body near the tank like stock? I would like to use a Y to put the feed on and the retrun and main feed. I would like to use AN hose and fittings which Y block should I take?
If I see a -AN8 Y-block could I use a reducer fitting to -AN6 for the retrun hose? second: or should I better use a -AN Tee fitting?

How to connect the hose to a 2001 fuel rail? what fitting or bung is needed?
I hope you can help me out guys, thanks
Peter from Holland

Baffles are a necessity if you corner. I have no experience with foam liners as a fuel motion control, so I can't say if it's better than baffles...but I know baffles work.

For a street car with no cage or safety liner for the fuel cell, I'd avoid aluminum. An accident impact will open an aluminum tank much more easily than steel.

I have no advice on the y-block question unfortunately. I mounted an Aeromotive regulator in my engine compartment, and reused my '82 Camaro feed and return steel lines.

Thanks, so i should go with stainless steel?
About the Y-block, I am more thinking towards the Tee fitting, using the the straight for the feeds and the 90 degree one for the return with a reducing fitting, this should work right?
thanks

Why not just find a 99+ plastic tank?

If the choices are stainless steel or aluminum, I'd go stainless steel. With baffles positioned correctly for your pickup. Make sure you bring them your in-tank pump and pickup assembly so they can locate the baffles in the right place to keep the gas in the right place...around your pump's filter-sock.

As for the T or Y block...where will the regulator be?

Thanks, I will use the 2000 LS! fuel pump with internal regulator on the return end.
So instead of the stock block I will use a Tee fitting, should do the same isn't it?
thanks

Glad to see you received the fuel pump.

For the fuel rail, I used some Russell Hard line to AN adapters. Jegs and Summit sell them for like $7. They clamp down on the fuel rail and leave you with either a female or male AN fitting to hook up to. Works great and is easier than flaring or brazing.
