I want to purchase the Tanks Inc kit for my 72 Cutlass what's going to get a LS1 with a bigger cam. Do I need the High Flow 250 Liter Per Hour Pump for my LS1 or the Deluxe 190 Liter Per Hour Pump? I shouldn't need the higher 400 LPH pump since I'm not going to make 500+ HP. I hope to be close to 400 but I don't know.

I read that 3/8" or -06 AN is ok up to 375 hp. Will I be ok with this size or do I need to go up a size? I think I am going to run a hard line front to back enless there is a better nylon high pressure fuel line that other people have had good success with.

Im using the Deluxe 190. Works great, im using -6 steel braided front to back, with the Corvette Reg/Filter about a foot from the tank. So the return is right there.

Im just under 400whp on motor.

Dude... its like $10 more for the 250 one. Go big or home at the price ! LOL

3/8" or -6 should be good..

Will the 250 be overkill or will it not matter because the regulator will/should take care of it?

Most will go with the Walbro 255, I would not be overkill. I have one in my chevelle and it is a stock engine that puts 330rwhp only.. A regulator well handle regulating the pressure as required or adjusted to.

IMO $10 is not going to kill the budget.. and in this case, better to have it that not !

This way should you do any bolt on's or mods (H/C/I) you well be good.

I agree. The regulator will take care of it. I will be going the Walbro 255 route myself.
