Title: What is this?? Leaking oil bad!
Post by: g35-coop on February 20, 2012, 02:19:41 PM
Im leaking oil from this and it looks like its coming from where a hose used to be connect??  It is right behind the carb and just under the distributor????  If Im missing a hose where does the other end go to?  Is it an oil pump or?????

That is your fuel pump.

Yes 87suzi is right.

this tube is not connected to anything, it a vent & excess oil on the back side of the pump diaphram is draining here.
it could be time for a new fuel pump. also check to see if your PVC valve is working correctly, if bad, it could be forcing oil out here.
Note, if you replace pump, be aware that there is a small push rod that is in the side of the head to work the fuel pump
lever, don't let it fall out or your new pump won't work.

That is the fuel pump.  If there is oil coming out of the open tube, you need to replace the fuel pump ASAP.  Oil coming out means the diaphragm is ruptured and oil can leak out and gas can get into the engine block.  After you change the fuel pump, change the engine oil and filter, because there is a good chance you have gas in the oil.

My sami is doing the exact same thing!  If you find a good deal on a new mechanical fuel pump, please shoot me a message and tell me where you got it!  My leak is very minor, otherwise i'd be ordering the part right now!  Good luck!

You can also get a factory Suzuki one through the dealership for about $4 more. Some Suzuki dealers I've found online sell them for even cheaper but shipping kinda kills the deal.

I had to change mine out not long ago, the hardest part for me was cleaning all the old gasket off, it was a pain.

I also had to replace mine this week. Got it from Napa and paid $80  :-[...ouch!  To add to the pain, the new pump is actually a little noisy. Guess I'll have to see how if it quiets down.
