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?

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.

Scott- How did you plumb the sender into the 6 line?, Im thinking TEE mounted up on the back of the engine or firewall close to the rails?

Thanks Rich

Rich, sorry for the delay, I missed this post.

Russell makes an inline -6 fitting with a 1/8 NPT fitting:

Thanks- Last night I was thumbing through my russell catalog and saw that fitting. I assume you mounted it right off the fuel rail?

I believe you told me your regulator is mounted in the back , did you run a short piece of #6 line from the return port on the reguator to the tank?

Let me get this right- #8AN from the in tank fuel pump to the regulator- out of the regulator with # 8AN up to the firewall through the filter then convert to 6 up to the fuel rail?

Thanks Scott
