OK THIS IS MY FIRST POST IM NOT SURE IF THIS IS THE RIGHT SPOT BUT HERE GOES. I HAVE AN 86 FORD JUST KIDDING AN 86 NISSAN SENTRA I SWAPED THE MOTOR FROM A 89 SENTRA WITH ALUMINUM HEAD BORED OUT AL KINDS OF STUFF ,BUT THATS NOT THE PROBLEM. I HAVE WHAT I THINK IS THE OIL PUMP NEXT TO THE OIL FILTER THAT HAS THREE LINES COMING OUT! I DONT KNOW WHERE THE HELL THEY GO. ALSO THE FUEL CANISTER WAS BROKEN WHILE REMOVING THE ENGINE.I WAS TOLD I CAN BYPASS THIS PART BUT IVE HAD FRIENDS WORKING ON IT WITH ME AND IM LOST. I DONT KNOW WHAT THEY HAVE DONE OR PUT THINGS. HE IS IN JAIL NOW AND CANNOT HELP. I GUESS IM ASKING IF SOMEONE HAS A LINK OR SOMETHING TO SHOW WHERE THE OIL PUMP LINES GO AND HOW DO I BYPASS THE FUEL CANISTER. ALSO MY THROTTLE CABLE DIFFERS FROM THE MOUNTING BRACKET, 86 AND 89 ARE DIFFERENT. DOES ANYBODY KNOW WHAT OTHER THROTTLE CABLES ARE COMPATABLE. I NEED ONE WITH A BALL AT ONE END FOR THE GAS PEDAL AND THE TWO BOLT THINGYS TO HOOK IT TO THE MOUNT ON THE CARB.MOST VAC LINES ARE GONE OR PLUGGED. WHICH FUEL LINES FROM UNDER THE CAR DO I NEED NOW THAT THE FUEL CAN IS GONE.THERES LIKE SIX I ASSUME I ONLY NEED TWO. HERES MY NUMBER IF SOMEONE CAN HELP BETTER OVER THE PHONE. JASON 352-217-1641 REAL BALL BUSTER IF YOU ASK ME

WELL AFTER LOOKING AT THE LINES ITS THE FUEL PUMP NOT THE OIL PUMP. SO I NEED TO KNOW WHERE THE HOSES GO TO HOOK UP ALL FUEL LINES WITH OUT THE FUEL CANISTER THATS BOLTED TO THE FIREWALL. ALSO I HAVE THREE UNITS THAT TAKE THE SAME KIND OF PLUG STARTER, DISTIBUTER,AND A COOLANT SENSER. I ONLY SEE ONE OF THE PLUGS I NEED. LOOKING AROUND I DONT SEE THE OTHER TWO. COULD THEY HAVE BEEN TAKEN OFF OR WHAT. AGIAN IF YOU THINK CALLING WOULD HELP MORE HERE IS MY NUMBER. MY NAME IS JASON 352-217-1641 ILL POST MORE AS I FIGURE IT OUT

now its running but the acel pump pours fuel from the carb i put another on from another carb but it still leaks???? how do i solve this?

Possably a stuck open float?

What carbureator are you using?
The 89 sentra in the US comes stock with a TBI not carbureator.

THE ENGINE I USED HAD FUEL INJECTION ON IT. I JUST PUT THE ONLY MANAFOLD ON IT WITH THE SAME CARB. WHEN YOU PRESS THE GAS A ROD GOES TO THE OTHER SIDE AND DEPRESSES A VALVE. IT LEAKS AFTER ABOUT 30 SECS. AFTER SWITCHING THE OTHER VALVE OUT ITS ALITTLE LONGER THAN THE FIRST OR ITS NOT IN RIGHT, OR ITS THE FLOAT I DONT KNOW IM NOT A FIXIT KINDA GUY! IM THE GUY YOU TELL ME WHATS WRONG AND THEN I CAN DO IT. HOPEFULLY THIS IS THE ONLY PROBLEM MAKING IT RUN LIKE "ISH"

Ok so you are using the carburetor from the E16s that was origonally in the 1986 Sentra?

If the accelerator pump leaks fuel from around the shaft that you push on, it could be a number of things. First off it could be that the rubber plunger that slides inside the accelerator pump housing could be dried or hardened and is not sealing, It also could be ripped. Also if the passage where the fuel is supposed to be sprayed from is plugged it can do that. If the gasket was worn or ripped on the cover it can leak an excessive amount of fuel out of the carb.

What you need to do is turn the key on and allow the electric fuel pump get gas in the fuel bowl, then look down the carburetor while opening the throttle. There should be a jet inside the carb that you can see spray fuel. If there is no fuel spraying it could be bad accelerator pump plunger, or plugged ports.

A stuck open float would make a puddle of fuel all the time the engine is running, so it is not likely.


A side note...
did you bi-pass the mechanical fuel pump? Usually the vendors that sell used GA16 that have the mechanical fuel pump supply a plate to cover the hole, and you just remove the mechanical pump alltogether.
The charcoal canister can be removed in some states depending on your emissions laws. Usually the charcoal cansiter has vacuume lines that you can plugg off, and a return fuel line that goes the gas tank that also would need to be plugged off. The only down side to bi-passing the charcoal canister is that you will have lower fuel economy.

WELL I STILL HAVE THE MANUAL PUMP. WHEN I REPLACED THE ACEL PUMP BOTH SEALS WERE GOOD AND SOFT WITH NO CUTS. BUT I REPLACED IT ANYWAYS. I GUESS I WILL JUST ELIMINATE THE PROBLEM AND BUY ANOTHER CARB!
