Planning a lq4 Triple 12 7875 turbo 4L80e in a 2dr 99 Tahoe.. Trying to figure out best fuel system for higher Hp needs. Going with a Walbro 450 in tank. Do I go corvette filter route to a newer truck intake? or use a older intake with return fuel rails problem is I read that the walbro 450 with older rails tend to raise the fuel pressure and cause tuning problems. Or is there another possibility I am missing

thanks

We have seen several corvette filters mess up with bigger fuel pumps and then they wont regulate fuel psi.

So I guess corvette filter is a no go what’s my other options

I'd just run a boost referenced regulator and call it a day. That's what was recommended to me and my setup will be pretty close to yours when it's all said and done.
