i am in the process of dropping a 408w stroker motor into my 87 hatch. i cant decide on the fuel delivery. i already have a 12 gallon cell and holley blue pump that was for another project. i know they have regulators that convert high pressure to low so you can use an efi fuel pump for a carb, car is originally efi. which setup would be easier and better for my application? should i keep my stock tank and stock fuel lines and just get a high pressure to low regulator? should i just go with the cell setup? are the stock lines big enough to handle my application? would i need a return line for the cell setup? what size lines should i use for the cell setup, if i go that route? for anyone who has done this swap, please let me know the best route to take and what your setup is.
351w fuel delivery?

the stock delivery line on a fox and a stock pump is all you will need for a carb setup. i guess thats what you are doing anyways. you already know you have to regulate it so thats no issue. and for a carb set up you do not need a retuen line.
I used my factory tank. However i removed the old fuel pump replaced it with a dummy fuel pick up and mounted a electric fuel pump outside the tank. I ripped the fuel injection lines and replaced them with 3/8 aluminium tubing lines. I installed the fuel regulator in the engine bay and ran push loc lines up to the carb. Worked very well for me.

make sure to wire in an inline fuse when doing it. and if you can wire it to a Key On 12V source. the only problem i see with that is that it wont cut off when pressure is aquired like a stock vehicle does. and i dont have an answer for that.

My brother ran a stock replacement pump with his carb along with a holley reg in his 90 GT. It ended up burning the pump because it ran full duty all the time. I ran the same setup in my 90 GMC truck. We both ran return lines as well.
