once again!


Recommended Posts

my fuek pump went out while on the free way. luckly i was able to get back to my car before any wreckers got there and tried to make a quick buck off my butt. we completely ended up taking my whole ignition system apart, put it back togeather, then i tested my fuel pump, and there layed the answer! ha! once again i have out smarted the old subie! :clap:

 

but thats not the worst part, i accideltly crossed spark plug wires 3 and 4. and took it out for a drive and thought there was too much fuel in the carb, so i looked at the manual and found out i crossed them. phew, feels good to be drivin the old subie again.

 

 

 

on a side note. if i have a high pressure fuel pump(4 to 7 psi) do i really needf that much? or should i go with lower psi pump, like the 2.5 to 5?

There's no reason to use a higher pressure fuel pump. First off, your engine isn't really going to benefit much from extra fuel, even if you do put it to good use by advancing the timing, etc.

 

But here's the thing: Your carb (assuming you haven't touched it) is going to just send that extra fuel right back into the tank anyway.

Double-check. If you don't have a fuel return line, then EVERY drop of fuel that the pump is putting into the carb is being used. I would say you'd flood the carb and the car wouldn't even run.

i can take a picture of it bu theres just one line running from the fuel pump to the carb. no return line.....i wonder if THATS why my car spits flames and small ammounts of black smoke(:confused: )
