I ran it by one of my chevy friends (!) and he suggested a stand alone fuel cell (3 gallon) with an in-line pump going to the fuel solenoid. Now this seems weird to me because I'm afraid of screwing up the air/fuel/nitrous ratio because if you 'tee' off the fuel rail, the in-tank pump (mine is a 255 lph 'high pressure' unit) will be giving near identical pressures to the fuel rail and the fuel solenoid/jet.<br /><br />Actually if I think about it, the schrader valve is pre-fuel regulator so it's seeing unregulated pressure from the pump, and the fuel rail sees something entirely different.<br /><br />Does this matter? Does the pressure the fuel solenoid receives matter? Does the fuel solenoid function as some kind of internally regulated device? So that say if I have an 88 lph in tank pump, or a 155 or 255 the fuel solenoid delivers the same amount of fuel (given the same jet).<br /><br />thanks for any help <img border="0" alt="[worship]" title="" src="graemlins/worship.gif" /> <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>jmcclesk</b> <br /><small>Member # 1355</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2002,10,26,20,45,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> Shade call me. it would take me too long to type. t-off the valve is the correct way <br /> </font> </td></tr> <tr bgcolor="#dedfdf"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>Milesblown03</b> <br /><small>Member # 27</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2002,10,27,3,16,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> The shrader valve is not pre regulator. The pressure at the schrader valve will be the same as the pressure at the injectors, hence the reason for the schrader( to check fuel pressure!) Now thats i think about it, the entire fuel system from the pump, to the regulator, to the fuel rail, willl all have the same pressure. The regulator will just dump off excess pressure (from the whole system) and dump it back in the tank. So, teeing into the fuel rail would seem ideal. I guess you could go crazy and add a seperate fuel cell, with its own pump,etc, but why? To much extra work for too little gain. As long as the in tank pump will support it, T-it and forget it!! <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>Pro50Eric</b> <br /><small>Member # 2065</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2002,10,27,7,35,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> Miles made good points and he was absolutely correct in what he said.

So tiny that there could be a problem with little crap like dirt plugging them. You also have to run the same octane gas that you have in your tank.<br /><br />If you put a cell and a pump for just nitrous and run the pump at 7-10 psi or whatever it calls for then you can use bigger jets for the same amount of fuel. You can also run a higher octane when injecting the nitrous which lets you run more timing. <br /><br />From what I’ve heard the recommended jets for fuel and nitrous have to be at a certain psi and I’ve also heard they give you jetting for both carb pumps (7-10 psi) and efi pumps (40-55 psi).<br /><br />Now like i said at the beginning, i don’t know shit about nitrous, what i just told you was stuff that I’ve HEARD, not facts, so unless someone backs me up on this info... ignore it. <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>shade-tree</b> <br /><small>Member # 298</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2002,10,27,14,29,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> sounds good, thanks Chris I mean Paint job <img border="0" title="" alt="[Wink]" src="wink.gif" /> <br />I'm sourcing a valve-core removal tool and will be having at it.
