LS7 Which regulator?

[ss dave]

Does the LS7 use a Vacuum regulator or not?
Trying to decide which to use for my LS7 tune.
Thanks

I'm using an Aeromotive 13101 and no vacuum reference.

Scott, what fuel filter and line size you are useing?

[XcYZ]

Up to the filter it's -8, past the filter and to the rail, it's -6. I can't remember off hand the brand of fuel filter, but it's a large capacity 10 micron unit with -8 fittings.

Thanks Scott!!

If i recall right the out port in Ricks tank was 6AN ? Do you have larger or did you just use adapter fitting there?

I used a Trickflow 10 micron filter.

My Rick's tank has -8 fittings, my fuel system is all -8 until after the fuel filter. My sending unit for the fuel pressure gauge is in the -6 line.
