<div> <font size="2">Those are good numbers on the fuel pressure.</font></div>



<div><font size="2">Too many other unknown variables for best plug, a fine-wire type like maybe B8 or B9EV NGK, if you can find them.</font></div>

<div dir="ltr">I recently acquired a fuel pressure checking kit so I decided to check the fuel pressure going into and coming out of the regulator on my Spitfire.   I had about 6 psi going in and 3 psi coming out.  Just as it should be, or at least that is what I have heard.  I have dual SUs.

<div><br clear="none">
</div>



<div>I'm looking for confirmation or thoughts about the fuel pressure.</div>

<div>Also, what spark plugs to use with my newly rebuilt 1300 with a shaved head and forged pistons.  I'm running 110 octane.  I don't doubt this discussion has been had already so if somebody can direct me to a thread that would be great.</div>

<div>Thanks</div>
