Rebuilding a Fuel Pump???
 

I am almost done overhauling my O-320-E3D. It has been fun, and I am glad I did it.

My question is the fuel pump. I have not really thought about it until now. I got a fuel pump with the engine, but I am not comfortable just bolting it on and going. Is there anywhere I can get the parts to rebuild it? There is absolutely nothing to it and I would rather do that than pay Spruce $180 for an overhauled one. Do I need to suck it up or is there somewhere I can get the diaphrams and spring (that's about all I can see it has)?

Also I was going to order oil and filter, any particular filter I should get? The engine has a spin-on adaptor. Looking Spruce for instance shows about 6 different part numbers of Champion filters. Also any good place to get these other than Spruce?

Thanks,
Scott

I don't know for sure the details of where to get the parts. I do vaguely remember from my A&P classes that once you get it apart, it's a pain to put back together because of the strong spring.

My first reaction is to just use it like it is, most failures of these, like vacuum pumps, are in their first few hours. Otherwise, I'd bite the bullet and by a rebuilt one. In my opinion, dicking around with fuel system components is something best left to the experts. I personally would not overhaul a carb or fuel pump, i'd send it out.

I broke down and ordered one this morning. To look at the thing and think I have to pay $180 for a rebuilt one and give my old one back is just painful. Kind of like the oil dipstick and tube I bought for $150 from ECI the other day. These engines themselves are so SO simple and yet the costs are just out of this world. Oh well that's the deal with low numbers in production I guess. I still think I will sneak in under $11,000 for an overhaul to new spec engine with E-mag and P-mag. I am happy about that.

fuel pump
 

Scott, I am just now in the same boat as you with the fuel pump, I didn't havfe one and found a good used one , but I think I would rather have a rebuilt one , I would much rather do it myself the cost of a rebuild kit, so was it for a carb setup or a fuel injection and where did you find the best price ?

I got the rebuilt pump from Spruce. FYI - the core charge is actually $100 not the $30 they advertise.

I searched the internet pretty heavily and could not find a kit or anything like that to rebuild it.
