Question Lp Psi???

You can see what I have in my sig. I can run my LP down to 2psi on level 2 (60hp). I thought that the new in-tank LP were supposed to be able to keep up better than the old style, but from the looks of it they are not..???? How low is too low? I have my de-fuel set at 2psi for now, but should I bump it up to 3-4???

level 3 on a smarty can drop lp psi to 3psi....so you may not be too far off although it does sound a bit low. Change your fuel filter and check your readings again.
