I just noticed yesterday when I started up my 86 samurai it was running a little rough (21F) an could smell fuel, I got out and looked under the sami and saw fuel streaming down onto the driveway.
Popped the hood and it appeared to be leaking from the fuel pump (all stock under the hood)
I shut off the motor and tried to locate any loose or cracks in the housing, unable to locate any obvious cause.....
So I started it up again and the motor smoothed out and started to run "normal" it slowwed to a drip then stopped.
No problem for the rest of the day!

Today same problem, cold start with rough idle and fuel started to leak from what appeared to be from the fuel pump. Shut off and looked for cause, re start and ran fine with a few drips and stopped and ran fine.

Any ideas?
Ha anyone experienced this?

Thanks

Willie

I could be wrong but it sounds to me that it could be a lose fuel line and personally I would switch the hose clamps to the screw down type, also would not hurt to replace the hose itself

Stuff expands when it heats up.  The same principle applies to exhaust leaks. Replace the fuel lines like doughboy said and use good clamps.

I am not sure about the Samurai pump that is mounted on the block. I do know that some fuel pumps are manufactured with a overflow or seep hole in them. When the internal diaphram begins to go bad then a small amount of gas would be released from this area. This could explain the rough idle while the pump is not allowing gas flow as normal (while the gas is seeping). Then once pressure builds the seepage decreases or quits and the vehicle runs smoothly. Maybe someone else who knows the Samurai pump more intimately will chime in. If not and if it were me I would start it and do a quick crawl with a good shielded light underneath and wait to see exactly where your leak is. Line leaks can be very pesky because the don't show their ugly drip until pressure builds and sometimes are hard to pinpoint. Either way this gives you a couple of search areas to review.

Look at the pump closely and if it is leaking I would replace it quickly. When the diaphragm goes it could leak fuel into the oil. Not a good thing. Jim

Thanks for all of the replies, will look and see on all mentioned above. Thinking just replace the fuel pump and get all new hoses and clamps. (I think that covers all mentioned too!)

If you were gonna do that, I'd just get a low pressure electrical pump instead.  Mechanical pumps are prone to failure.
