anyone know the differance between 4103 and the 4104 boost guages? and witch one do I need for the L?

 

Mine says 5704 on it? It's a Phantom...2 1/6.

 

Funny, I was just going through this myself.

4103 goes to 30 psi, 4104 goes to 35 psi. I'm looking at the 4103. These are both Lunar series.

Let me know if you find a price lower than $95. They all seem to be in this range.

Thats the only difference in the two?

 

30 psi will be easier to read and I doubt you'll be running more than 30 psi.

 

That's the only difference I could find...someone will correct me if I'm wrong.

I believe that is the only difference. Both these will work and it comes down to personal preference. I have a 35 psi one (Phantom) but many run the 30. I plan on going over 30 psi myself so I bought the 35 psi one.

 

NICE!!!!!!!!!!!
