my friend drove my car today just to mix up the fluids and run the car for a minute. him and my mom took it out to get gas and he said it threw a code.

he sent them to me and they seemed very odd and ive never seen them before. this is the second time the car has been driven since i did the fuel return setup. the first time was flawless and was about a 5 minute drive although i was there for neither of them. my friend told me that every time they started it up today it had those codes.

i did the setup exactly how gurov did it eliminating all of the stock fpr BS and running the feed line straight off of the 255 pump, through the hp autoworks rail, to the sx fpr and back to the fuel tank.

the pressur is set at 49-50psi with the vacuum plugged with my finger and about 40psi with the vacuum hose plugged into the fpr

the codes are as followed:

p0037 - o2 sensor ( i know about this one.. dont have a secondary o2 as of right now )

these are the ones im worried about

p0183 - fuel tank temp sensor
p0463 - fuel level sensor

it seems as though my pump might be getting warm? but its regulated to no more than 50psi so it shouldnt overheat.. maybe the return is shooting gas back from a warm fuel rail cause the liquid to heat up? and possibly splashing and the fuel level indicator making it go up and down rapidly confusing the ecu?

can someone please shed some light on this?
