6.0 in a 81

[PunishedC10]

Thanks for the info. I've read your thread on 67-72chevytrucks.com
Can I use the '85 fuel lines? I'm sorry for all the questions.

No problem. As far as the lines from the tanks to the switching valve, yes. And you should be able to use the feed line too. If you are running an older engine that uses a return line, you will need to run a return from the fuel rail to the valve. But if you are using a returnless system you wont need it then, just from the filter/regulator to the valve.

I changed my original idea a little, and I will be running 2 filter/regulators. They will both be between the tanks and the valve.

Wish I would've started with a pickup as clean as yours. Mine is perrty ruff. I only have one tank on mine.

I'm thinking of using a newer 6.0/4l80. I've decided that much. I really want to run headers so I'll see what's available and fits.

did you go with 6.0/4l80 or what's your setup?

lol never mind. Found project "Fred" I'm going to thoroughly read it thanks again

I only have one tank so my setup should be easier then the two tank setup.
