Just a few things to consider. Yes it's a little cheaper but there are reasons for that and once you start to weigh them out...
1. DIY: It's a DIY, so you have to break down your own bucket and do the install yourself. We break down hundreds of buckets and that doesn't always go well. If you damage yours in the process...now what?
2. Testing: Once you do get the pump(s) assembled, how do you test it and know the pumps are good and that the venturi hasn't been clogged in the process?
Pump: While Walbro 450 pumps are pretty robust a small percentage are bad out of the box. This typically presents itself as vibration and low flow, something you'd only catch on a flow bench.
Venturi: About 10% of our pump assemblies end up with clogged venturi's, this means the bucket will run dry and can burn up the pumps. This is why we test all of our pump assemblies for flows, current draw, and venturi functionality, so we know we are sending you a good working pump assembly.
3. Our pumps are sent with everything needed to install them and are plug and play, no sourcing additional parts.
4. Tech support, as you noticed, you didn't get the answers you needed, hence the reason for this post.
5. We've been asked numerous times to do a DIY option, we choose not to for many of these reasons. If we are offering technical support we want to know that you are starting with a good pump assembly and not be troubleshooting that as well.
We understand wanting to save a few bucks, but at the end of the day once you start factoring time, additional cost, and tech support, the savings could evaporate very quickly.
