Sounds like the diaphragm in your fuel pump is fractured in which case you need to replace it. When replacing, be sure to position cam arm correctly.

when you pull the pump off you will see a little metal rod. you need to turn the motor until the rod sits as far into the block as possible.... is anyone able to elaborate why for us?...
that oil coming out of there does mean the diaphragm is broken. which means the pump is pushing fuel into the oil, VERY bad. make sure you change the oil and oil filter when you change the pump. but its an easy job. i have absolutely no mechanical knowledge, and i did it with no problems. But DO NOT DRIVE IT until its done. fuel diluting the oil means its not lubricating properly.

quick question, has anyone else noticed how many people are reporting that their fuel pumps are breaking in the last 2 or 3 months?... :confused:

That's exactly what I've done.

Did you see my thread on this issue? I have a brand-new fuel pump and it's not seating on the head- leaking oil from the lowest part of the pump's mating surface in spite of RTV and a gasket. Something's warped, but the pump that I took off didn't leak, so I don't know what's up- I'm still working on it.

If I don't get this whipped pretty soon I'm think I'll just convert to electric.

i did it about a month or so ago too. but i think mine was broken for quite a while before i realised, because i was very stupid when it came to cars (still am, just to a lesser degree because of this forum). I changed the oil 4 times and the filter twice, and the oil still has a light petrol smell to it. so changing those is a must

The less pressure you have on the pump when you install it, the better chance you will seat it correctly. Why fight the spring pressure if you don't have to. i have done it bothways, but with the rod all the way in was easier.
How's that? :cool:

gives me peace of mind, because i didnt do that... it was most of the way out. just sat the pump in place and did both bolts up at a fairly equal rate... couple of turns on one bolt, couple of turns on the other...

I found it easier to turn the engine by hand until the rod was as in as far as it could go... then put on the pump.
that said, I would think about yanken the thing off and going electric.
has many advantages and never a chance to mix gas in the oil again.

i considered it, but no idea what i was doing... how do you go about that? obviously need a pump, but need some way to regulate pressure depending on engine speed and throttle percentage?? and (im assuming) some sort of metal plate to go over the hole where the fuel pump sat...

If you are tightening against the spring then you won't be able to judge the torque on the bolts correctly.

Ack tells us how:

Ack's FAQ Replacing a Mechanical Fuel Pump with an Electric Fuel Pump

I'm strongly thinking about this, myself. The idea of totally eliminating fuel/oil mix sounds like a good idea to me.

However, I have a brand-new mechanical pump and no good reason as to why it's not working/fitting. I want to solve that problem first then I'll feel okay about going electric. Hmmpppfff...

If the mating surface of the egine block is warped then it could be holding the pump arm too far away from the actuator rod shimming it up with gaskets and RTV just bring it further away from the rod. It doesn't move very much, so just a little distance will render it inefective or at least ineficient. Get a straight guide and check where the high spot is between the mounting bolts if you feel comfortable in griding down that high spot you can use an angle grinder to flaten it out. If not you can take it into a shop and have it done. Be sure to stuff the hole so that metal shavings don't get inside the block. Have a fire extinguisher handy since you'll be working around your fuel lines and make sure the fuel lines are capped off.

Exactly! And that's why I think it wasn't pumping fuel when I tested it.

All other advice noted.

What do you think of using this opportunity to just go electric?

Electric pumps are inexpensive and easy to install. You need to get a low pressure pump that's internally regulated or get an unregulated pump and put a regulator in-line. Since your pump isn't working you can either cap it off and seal it to the block with RTV so you don't have an oil leak, or you can make a blanking plate to go over the opening. The electric pump won't last you 10 or 15 years like the mechanical one, but if you can't use the mechanical pump then you don't have a lot of options. If you can't return the pump you just got, you may be able to sell it on ebay. It seems that a lot of samurai's are coming up on the end of their fuel pumps life expectancy. (judging from the flood of inquirys lately about changing fuel pumps)

I've been reading Ack's FAQ and some other sites and have the parts lined up on Amazon. Looks like about $100 for everything by the time I do shipping and all that.

I might just toss the new pump on here, too. I assume we have a classified section...

Are there any ADVANTAGES to an electric fuel pump? Besides eliminating the gas/oil issue, which seems to me like a pretty big advantage, actually.

advantages. they are easy and inexpensive to replace. If they do wear out you don't get gas in your oil. Disadvantages, they don't last as long.

Perfect. They'll last 2 years, right? Once I have it set up, I don't mind replacing a $40 pump every 2-3 years as routine maintenance.

I set up mine as a pusher... mounted on the frame near the tank so I must have done it wrong... It's lasted about 10 years so far...
shoot, when my parts washer pump died I used an old 110v to 12v converter I had and got another fuel pump for the parts washer.
Cheap and simple.

I got my manual pump working. See other thread.

I will still probably switch to electric but I can do that later, AFTER I've driven Suzy around a bit to see if she'll even suit my purpose. I'm sort of holding on to my modification $$$ until I see how well she's going to work as a run-around-the-ranch rig.
