Suzuki samurai fuel issue

Friend bought a samurai for deer lease which has a electric fuel pump and a carbureted engine. Engine runs fairly well until you get to higher driving speeds 20mph+. At this point the engline begins slowing down and will eventually stall out. Motor will restart and do the same thing. Its a older model samurai and there is a small fuel regulator installed on the fuel line. Rubber fuel line can also be squeezed together by hand. Any tips would help. Can this be a problem between the fuel pump/carburetor?

You need to find out what psi the fuel pump is. You need to run a "low" psi pump. They usually run 2-5 psi. Then you need to buy a good fuel regulator (not the dial type, those are useless) and set it to 3 - 3.5 psi.

Try and pull the carb and check your jets and make sure that they are cleen and air filter be perty cleen if that does not work and you thing it is a fuel problem then check your fuel line and fuel filter and see how cleen they are it may be as simple as dirt clogging your fuel or something worse but try that

    I might add that recently in working with friends, we have found "stuff" in the fuel tank blocking the flow. With the fuel line open and the key on (electric pump, right) see if you get a good dependeble flow. Now, I just had this happen..........my catalitic converter plugged up and shut my performance down. Removing the fuel tank for cleaning is no easy job !!!!

The car do not start when it has been off for a long time like overnight...when it does it is with a lot of problems until the engine is really warm. when it hits up the problem disappears until the next...


hi,, check the fuel pump,or better still add an electric fuel pump assuming ur car is a 1.3 king and not the mpfi. further still check the carb and timing, spark plugs. also depress the accelerator couple of times before u turn the ignition and also depress the clutch pedal while starting ur gypsy.

How to adjust air fuel mixture on a 87 suzuki samuria


On any carburator,one screw is for the idle speed, the other the air/fuel mix.Start the engine and let it get plenty warmed up. Adjust the idle screw to make the engine run slow. Turn the air/fuel screw in until the engine starts to die then out till it starts running loady.You want the screw between these two locations. Adjust it till the engine runs the fastest. Now adjust the idle speed screw to about 1000 RPM.
I hope this helps you.

89 Suzuki samurai fuel issue


sounds like the electric fuel pump is failing the backfire is a result of a really lean fuel mixture, it is hard to say if u did any damage, most likely not because the pump is inside a anti-slosh baffle

I just ran into this problem as I was rebuilding my 1.3 engine. When you put the mechanical pump back on, you have to be sure the rod that pushes against the pump is all the way in, check this with your finger, you should only feel about 1/4 inch of the rod, if you should feel more, turn the crank with a wrench until it goes in all the way. Then put your pump on making sure that you start both mounting bolts before you begin to tighten, as you tighten gently pull back on the top of the pump, so the lever will line up with the pumps push rod in the head. Your pump will work fine after that.
