Just kidding brother. No dude, I seriously don't know what you mean. |
LOL ---- Okay - Okay!
Flooded head -- means does the fuel flow to the pump intake side without any help (suction). So it would be about like saying -- is the PUMP lower than the TANK
Yellow? Yeah that's the color of my race gas! Did I really say that??? LOL I corrected the post and substituted the word FUEL for Yellow.
So what happens with most electric fuel pumps -- they're not made to SUCK fuel - they're made to PUSH fuel -- so if the head (pump) is flooded -- the fuel flows to the pump naturally -- and the pump only needs to push it along...... IF you have to lift the fuel -- i.e., the pump has to SUCK fuel to feed itself --- the suction can create cavitation (air bubbles) - and if it's too severe can cause the fuel to "boil".....
I'm really just trying to help get this sorted out - and not being able to see the set up etc - causes questions.
