New and unimproved kohler fuel pump

[dodge78 94]

I had little faith in it when I ordered it and it did not disappoint. The main concern was can I get the fuel line connector out when it breaks and are there replacement parts. I called them and they said yes on both accounts. They even sent me a pdf file of the instructions because I did not want to open the package incase I wanted to send it back. I should have sent it back.

After I had it installed and was putting the fuel line (brand new soft plyable hose) from the pump to the carb, (thats why I said when and not if it breaks) it broke. I have had 20 year old car engine plastic parts put up more of a fight. How am I suppose to feel confident this thing is not going to break when it gets cold, it was only 16 degrees out when I did this. The parts were in the house until I started and then were outside maybe 1/2 an hour before this happened.

For the amount of money this pile was .... I need to find a source for a rebuild kit of the old pump.

Not sure I understand how it broke? :scratchead:

I agree with Craig, I have several of the new plastic pumps and never had a problem yet.

I believe a member here sells rebuild kits "Buckrancher"?, also in the pinned links section there is a place that sells a rebuild kit for half of the cost of the plastic replacements.

From the instructions, I think you will have to use the retaining ring to depress the 2 flat tabs to release the (broken) fitting.

You will probably need to use a needle nose pliers to help remove the broken fitting.

I think Brian (buckrancher) only sells the diaphragms for the vacuum type pumps.

dodge78,

I'm not a big fan of these plastic pumps either, but I've only ever installed just one. No particular problems installing it, but it did feel flimsy.

I did notice after more than a full season of use that it was leaking from the outlet. Turns out I had cut the fuel line from the outlet to the carb just a tad too long, and it was putting pressure on the pump outlet fitting. I cut off a small piece of that section of line and reinstalled it, and the good news is that I haven't had any problems with it since then.

Without having the pump in front of me to look at, and assuming you can find a replacement, I think KC9KAS' advice for removing the broken fitting is right on. Take your time, maybe find a warmer place to work (I know MY hands don't function well at 16 deg.).

Good luck!

Kit AC-4-S looks like the diaphram I need.

Not sure I understand how it broke?

I am not sure why it broke either. It may have been a cold injection where the mold or plastic was not warn enough? I only used two fingers and a thumb to move the hose. I did not look at the connector because I was pissed because I needed the tractor.

I had thought of putting the connectors at an angle towards the aircleaner to make the hose longer but thought it might leak.

I have the part numbers for the connectors

I also found 1/4 straight 2529409

I will see who has what around town. And the big news is that I won a rebuild kit for the original pump on ebay. Should be here about thursday. It cost about $175 but it was in a lot with about $800 worth of stuff, so be looking for some cheap stuff for sale soon.
