Okay I think everyone here has blown the whole thing waaaaaay outta proportion in reality it works good for me and it saved alot of time both now and in the future, if you dont wanna do it thats fine I think its funny just because its a gas line everyones like OMG its gonna explode if its modified you guys have been watching F&F to much " NOOOOSSS " hahah
heh, no, not quite.
actually, our fuel systems use a vacuum based fuel pressure regulator. even if you're still on the stock FPR, and you increase boost think of it like this:
stock base fuel pressure is 40psi with the vacuum line off. when you put the vacuum line back on, it drops about 10psi. (so now your idle fuel presure is at about 30psi) now, when you rev the motor, even at idle, NOT boosting, your fuel pressure will rise in accordance to how much vacuum is lost. (read: when vacuum gets closer to 0 pressure, and boost, fuel pressure is RAISED)
SO, when you go into boost, (remembering that we have a vacuum based fuel pressure UP vsv, and FPR) your fuel pressure will RISE in accordance to how much boost you're running.
Now, when you're boosting 10psi (for example) your fuel pressure will most likely be in the vicinity of 55-60psi or so. now take into consideration that the entire fuel system, from the fuel pressure regluator on the return side of the rail, ALL THE WAY TO THE PUMP IN THE TANK is under that 55psi of fuel pressure.
and finally, think of how comfortable you feel about a small piece of clear plastic holding 55psi (or higher if you're boosting more) of fuel pressure, and that if it explodes/pops that raw fuel will spew out onto your hot exhaust and most likely ignite. (remembering that the filter is betweent the fuel pressure regulator and the pump, so it's under constant pressure)
and keep thinking that as long as your ignition is on, your fuel pump is still running, so that fuel is just being pumped straight out onto a hot exhaust.
honestly, i'm not saying this to be an idiot, i'm not trying to discourage you from innovative ideas. i'm trying to help protect and prolong your life, others on the road, and your car.
and for the record, most of us are not F&F watchers
infact, i hate what F&F has done to supras...
