Ok so shizzle got weird. So I had a frayed wire on the top of the tank where it connects up top of it. Idk if that was the problem or not. My other issue after snaking in the tank, not by me but a friends shop, they said hmm you have gas in there but looks to be not enough. So we gassed her up, repaired the wire and on she goes and runs like a champ. So I have an aeromotive stealth 340, is there any difference than a stock fp in regards to length etc. why could I run my stock fp when it was basically stock with no issues to empty but after all this motor change, injectors etc etc fuel pump would I run into issues with less than a quarter tank?? They also checked the power from ecu etc back to fuel pump relay, relay to rear and all still powered up and checked out ok. Here is my other question. As I said when pulled my stock cluster out I remember having a quarter tank. I installed these new gauges and then my fuel gauge read 1/2 and then after a few starts 3/4 full. So after manipulation and adding in about 8 gallons of fuel my gas gauge went all the way over to empty but slightly past. Almost like it went reverse of what it was suppose to do with a full tank. Is this possible that some how it’s reading backwards?
