Fuel Pressure Problem 22re
« on: Mar 17, 2009, 06:42:07 PM »
85 toyota 4runner 22re been sitting for a wile when i start it it idles fine but when i give it gas it hesitates like its starving for fuel. but when i pinch off the return line that goes from the fuel pressure regulator back to the tank it runs fine. i replaced the pressure regulator with one from the junkyard and it still has the same problem. any ideas? :dunno:

I think you are talking about the fuel pump and the return line that sends fuel back to the tank.

Look at the sight glass in the front of the carb.
The fuel level needs to be in the middle or better yet just below.
When you pinch the return hose, the fuel level in rising in the bowl and the stumble goes away.
Changing the pump did not solve the problem.
Sounds like you have a plugged accelerator pump nozzle.

Could be a fuel filter problem or even a fuel pressure problem with the pump. If the filter is clogged insufficient fuel to the rail could be a result. Hard to diagnose things over the internet.

I changed my fuel filter and the same problem. I am going to change the fuel pump.  The thread topic "22re powerloss"  has the same problem to.

Does it run better when you pull the vacuum line of the regulator?  If not you could have a bad regulator.  You need to check your fuel pressure before you start replacing too many parts.  It could be something else causing a super lean condition, and it may only be coincidental that pinching the fuel line fattens it up enough to run better.

You can use that lower banjo too.  You just need to find the correct adapter.

you have a local HF ?   I know they have fuel P kits
 I see u said the trucks been siting for a while   hows the gas its self ?   after 30 days  gas start to go rancid  just like milk :)   

If your gonna do the fuel pump or change the sock  I suggest a real good look in the tank to + fuel lines .  also try testing for water in gas / or treatment.
