How many fuel PSI should a sst 120 be set at? I thought it was (3)?
fuel psi is depending on pump you use
and no less than 80 gph
when using an automotive pump as holley(red is the bare minimum),ect
stagnant pressure NO less than 7,,,recamend 8
cause automotive brand pumps are NOT designed to run mixxed oil in fuel
and the built in regulator or remote tends to get sticky and fluxuate in time
and when using a flow pressure testor never less than 6 1/2 psi
below 6 psi and 80 gph motor will lean in high rpms

never 3. buy a weldon set it at seven an your good to go.make sure your filters stay clean or it will lower your psi.i have all sorts of red an blue pumps an regulators.an tested them all. but the weldon is the best.
i have 20yrs of outboard racing using all of the other brands
so also all i use is weldon
super high volume
and pressure stays consistant
more expensive but cheaper than a rod hanging out of the block
buy just 1 and have it forever,,,not just a yr or so
on another thread i reccamended the weldon
over automotive brands
so i held back on this thread and just stated pressure and volume
