S10 Fuel system cant hang, Changes will be taken
My mods are in my signature. I am currently installing the heads and cam so right now these issues are occuring on stock LS1 heads and cam.
Here is the current fuel system:
Walbro 255lph in tank
Stock S10 fuel lines
Stock LS1 injectors/rails
What happens:
FP and resultant AFR are fine N/A, but when I activate the nitrous it goes lean for a bit and then slowly catches up. Not sure if its the pump or the lines causing the issue.
Anyone know what the stock S10 fuel lines can support? If I toss a Walbro 400lph pump in there could this resolve the issues or should I step up to a larger feed and return? I would like to keep the stock rails (97-98 vette return style) so I will need to adapt from the standard size inlet outlet ports on the rail to the larger feed and return. I will be installing 42lb/hr injectors when the heads and cam go on. Thanks!!
