Shurflo pump rebuild kits??
I think I have damaged my Shurflo 8000-543-238 pump by running it dry last night. :sad: The motor runs and the pump pressurizes the system, but very slowly. It just doesn't have the quick pressurizing that it used to.
My WI pressure gauge light is out and so I didn't see the pressure drop. I was breaking in a new engine and so I also had other things that I was worried about. :roll: The low psi nozzle was the only one that was being triggered, so as far as denotation I was still in good shape. Anyway, my question is: Does anyone know a good supplier of rebuild kits for this Shurflo pump? I could do online, but I would prefer to find one in Denver, CO so that I can fix this sooner. Thanks for the help! -Craig |

Shurflo supplies repair kits for their pump. You can get the part number from their site:
http://www.shurflo.com/pages/Marine/...ir/repair.html Once you get the part number, you can order form their agents.

pump prime
I've had problems on a couple occasions getting the shurflo to prime. It appears that if an air bubble of the right size, gets in just the right place, the pump can airlock, seems as if the pump cycles, and all it does is stretch and compress the bubble or something like that.
Try to pressurize the inlet a bit, somehow. If you have a rubber hose on the intake side of the surflo, try squeezing it rapidly a couple times while the pump is running. If your pump is doing the same as mine did, its running at full speed and does not seem to move any water to speak of. When I squeezed the inlet line while the pump was running all of a sudden it changed from full speed no load to the normal slower stroke rate that quickly slows and stops as the pump comes up to pressure. Supposedly they can be run dry with no harm but I know the pump gets quite warm running at full speed no load. Larry |

Yeah Larry. That's what it's doing. I'll try what you suggested.
Thanks! By the way Larry, are you on RMDSM by chance? |

OK, for the archives:
Last night I was able to massage the inlet hose of the pump like Larry had suggested. The pump primed and is working normally again. Thanks for the suggestions! :wink: -Craig |

Good to hear it worked
Ah Good to hear it works --- seems to be a common issue, if two different setups have had the same thing happen.
My pump is mounted horizontally with only a foot or so of hydraulic head on the intake side, and a pre-pump debris filter FWIW, Quote:

The inline suction filter on mine became plugged and the pump lost suction , I noticed the "pump run " light staying on longer than the usual 3 seconds. I think its a good idea to have a warning system for low water pressure inside the car (as I have done now) to indicate if the pressure falls before a critical level. I do have a gauge , but its in the engine bay ,I cant fit any more gauges inside, I thaught that I had simply used out the storage and the pump was now supplying the pressure. :!: , when I stopped and chesked I only had 30psi on the gauge an it wasnt rising (since the filter was dirty) , it normally does within 2-3 seconds!! , luckily I did not go into boost and cause any damage to my motor. :idea:

SHURflo pumps
Only the SHURflo pumps with the Viton valves and Santoprene diaphragm are rebuildable to my knowledge. Kits are available through NorthernTool.com

Would it do any good to mount the pump off horizontal, so that air travels up?
