Hello all,

I'm new to Mercedes and the forum, so please be gentle! Lol...

I recently bought a 1975 280 W114.060 with 110.921 engine that is now getting some much-deserved TLC. I've found that there is oil coming out of the weep hole on the mechanical fuel pump. This car has a smog pump and I've learned that this requires a lever-type fuel pump to fit. A replacement pump seems to be a dealer-only item (at around $370). It's a Pierburg E3000-12084/APG.

Does anyone have a less-expensive source for these? I can find tons of the "piston-type" pumps, but these won't work here. I've been entertaining installing an electrical pump, but I'd rather keep things stock. Anyone else had to deal with this?

Thanks!

Greg, have you checked the link on top of this page??

Al,

Absolutely! I've checked with a number of parts suppliers and they all seem to only sell the piston-actuated type of pump. I need the lever-type.

Here is what mine looks like...

Does VA still require emissions equipment checks for 1975 vehicles? If not, remove the air pump, and use the straight fuel pump.

No, they don't, but I'm one of those guys who likes to make everything work - stock. Besides, I've heard that because mine is a lever pump and the other one is piston, that I can't just use the other one? I'm guessing that there's supposed to be something in between the pump and the block to convert the lever action to piston?

Hi Greg
I have exactly the same problem , I can not locate where to buy the fuel pump with a lever
original pump is pierburg E20064 4319

could you pls advise where you could by the original pump

many Thanks
MS

I'd block off the mounting at the engine and move towards a low pressure ( 2 - 3 ish PSI ) electric pump.

Carter , Facet , Airtex make solenoid pumps, just be sure to use a 2 terminal oil pressure switch so the pump stops if the engine stalls. The solenoid pumps do make a noise when pumping so attach it with soft mounts. I think you can get a low pressure motor pump these days.

MS:
Please see the above quotes; although a conversion to an electric pump will indeed provide a source of fuel, it will also, as noted, present a noise problem.
The easiest, and very likely the lowest cost, solution is to delete the air pump that is in the way of the original style, straight/piston pump, and then use the readily available straight pump. The straight pump was used in 1973-4. and can be used once the air pump is removed, contrary to rump's misinformation.

Will the fuel pump from a M130 (that came with a smog pump) work on the M110?

I know this is an old thread but if you have oil coming from weep hole, remove the pump and fill the lever void with grease.
