Oh, and Eric, I measured the opening of the restrictor to be darn close to 1/32".

@RAS: The insulation is a good idea. Can you send me the specs of this material?RAS wrote:One difference is that I've insulated my boiler (with 300-degree F foam),
Best regards and have a nice evening.

You bet - it's called "Elastomeric Sheet Insulation", and it's 1/2" thick (which fits perfectly in the space you've got around the boiler), is easy to cut, and sort of easy to install. I did it when my machine was apart - this made getting around some tight spots far easier. On top of the boiler, I used a scrap of some insulation I bought from Orphan Espresso - I think it's 3/8" thick.
The elastomeric insulation I bought is rated from -297 to +300 degrees Fahrenheit, and comes in a BIG sheet (anyone interested in some contact me via PM) and is called "Nomaco Kflex". It's intended use is piping, ducts and tanks...
Here's the best picture I could find showing at least part of my insulated boiler:
You can see some of the "Gorilla tape" (I think it's also called "gaffer's tape") that I used to hold pieces in place. It's rated for high-temp, and is quite tenacious... some say it'll even stick to water!

That size and that pump work well together - ABOUT 0.5 bar pressure loss at AVERAGE brew rates. You MIGHT consider having Fluid-o-Tech rebuild your existing pump - or at least get an estimate. Shipping costs may erode the savings BUT at least there won't be any doubt as to the configuration of the snout and the sealing of same.. . . I measured the opening of the restrictor to be darn close to 1/32".
