Noisy WVO pump

[kevinj1]

I have had this WVO design pump in my truck for about 6 months and it has 6-7k miles on it. Lately it sounds like a straight cut gear pump, kind of grinding type noise, It is loud enough to drowned out the sound of the exhaust, Is any one else having this problem


Thanks Kevin

I would a call to Leon would likely solve your problem.

I emailed Jason about it Wednesday and his answer was "They do that when the oil is cold. Is it still holding pressure?" .... I replied its working ok and at that time it was holding psi. I noticed yesterday after it got hot the psi would hold unless I floored it then the psi would drop to 50 psi like a clogged filter and the jump back to normal and bounce occasionally. I was wondering if anyone else that has a WVO Design pump and if they have had the same problem
Thanks Kevin

filter is before or after the pump? You might get lucky and just have a lot of build up on the "in" part of the fuel pump well unless you have a high micron prefilter like FASS does with theirs.

I found water in the pump motor, I received the new motor today. I filled every crack and crevice with silicone and will be installing it tomorrow. Many thanks to Jason and Leon for standing behind there products

Where in the hell did the water come from?
Is the pump under the truck? And if so, I wonder how water can get into the armature?

Yes the pump is under the truck. I don't know exactly how the water got in.
Addition I took a good look at how I had the pump installed and found I had it so were the wires go thru the housing were directly on top at 12 o'clock. and the water must have wicked its way in.
