1985 Ranger 4cy 2.3 gas.
Okay so here we go. . .
The long and short curly end of it I have air in my fuel lines. There is a section of line that is see-through right before the canister fuel pump. I can see both the return and the one it sucks from. Or I think it's the one. One is blue and one is whit/clear/yellowed. On the other end of the canister moving towards the motor, the blue line enters fuel pump then from there up to fuel rail. Then the return part of the rail is connected to the white/yellowed line that goes back into the canister filter housing. I'm not sure what happens in ther. If they combine or what. It should reunite the return with the tank right?
But back to the bubbles, i can see in the lines and see space where air is and sometimes no fuel moving, in both lines in different times and at same times.
Things I've done.... to fuel system : it had a bad sputter and loss of power under normal driving. So I've replaced the filter, pump and pressure reg valve. No love tho.... I've dropped the tank to see if a connections were loose. I've taken off and re-attached connections (I can kink fuel hose after pump and it builds preassure in a second flat, also pumped gas into a bucket with no hesitation very quickly) so I'm saying connections up to pump are A+
So someplace I'm catching air and it's getting in the lines right? Also I have zero gas leaks, I check every morning and when I get home from work, looking for wet spots under and up inside. So idk what the hell to do next.
One thing I can think of is after changing the filter I didn't re fill the canister, that may cause a big air bubble? But i pumped like a half gallon into a bucket no problem. So I don't think that could be it!
Also idk if it makes a difference. . . The kid that neglected this truck so bad before me wired up the fuel pump to a switch so it's manually turned off and on. It's just stlraight 12v from battery. Whould anyone know is constant power mess with the pumps performance. I plan to wire it back eventually
Any feed back is appreciated Thank you!
