I picked up this MFI setup off ebay ages ago, cause it was there. I have finally decided to have a bit of a look at it, as i have an engine here i wouldnt mind using it on, mostly for shits and giggles/learning curve.
Now, the main issue is its a bit of a peculiar setup. Firstly im hoping that after reading this (soon to be long winded) post someone might be able to work out wtf brand it actually is. Also im going to say what i think all the stuff does so hopefully someone who knows more than me can correct me when im wrong.
The second issue is it was all polished at some stage, the particularly annoying part of this is the pump was polished and the pn was polished off it. All i can see on it is a bit of what appears to be an 0. Not overly usefull.



I did a bit of a naughty and pulled it apart, mostly to see if the impeller had a number on it (like hillbornes 00,0,1,2 grading system or similar) but couldn't find one. While i was in there i had a good look, to my untrained eye it appears to be in rather good nick. Very tight tolerances, no scuff marks, etc.



The only identifying marks of any kind i could find on the pump was the code "IL35" stamped underneath the end plate.

The other thing i found peculiar about the pump is that it doesnt have a built in bypass (that you run your pillbox off) on the pump like most of the common brands do. But i'll get to that shortly.
I also jerry riged a half baked test setup with a bit of line going into a fuel container and spun it with a power drill. frOck me swinging does it move some fuel. Part of the reason for doing this was to try to work out how much it pushes per revolution, i had the great idea of spinning it with a shifter, counting the turns required to move 500mls of fuel into a graduated container, but couldnt spin it fast enough to actually get it to work. If i had an optical tachometer i could work it out easily with my power drill, so i may have to beg borrow or steal one.
Now, onto the throttle body.



Now, apart from being rather sexy, it just seems to me to be a 2 1/4" throttle body with a pillbox/barel valve setup all in one nice neat little unit.
took me a fair while looking at it to work out how it worked, but it seems with this setup you dont need to run the pill in a return line directly from the pump like a lot of other setups.
It has a Pill cover, and a cover marked with 3

And two more covers marked 1 and 2. 1 is in the lower left in that pick.
It also has three fittings coming out of it, One marked "in", one marked "out", and one unmarked. The one marked "in" is obvoiusly the fuel feed from the pump. The one makred "out" appears to be the return from the fuel tank after the pill. The unmarked one appears to be the feed to the nozzles.
Under the covers 1 and 2 are a spring and a little valve. The valve under 1 has holes in it, the valve under 2 doesnt.

Thats the one in 1. The one in 2 looks the same but without the holes, and it has a stiffer spring.
It also has a rather peculiar looking barrell valve.


The notch is inline with the main fuel feed, obviously the further around it rotates the more fuel it allows past. The hole in the side that goes to the end is in the main fuel feed when the barrel valve is in the idle position, im guessing its a slow speed bypass of some description.
The cap marked 3 holds a spring that goes against the barrel valve, im guessing its just to keep it in place.
From what i can see valve 1 is in there as a bit of a restriction between barrel vavle and the pill. The valve 2 is in the port that the hole in the barrel vavle (the one i believe is a low speed fuel bypass) and runs to a port past the pill, into the return.
So, wtf do i have here? I have some other gear laying around, two nozzles, eight nozzle lines, some othe rrandom lines, a lot of crap that i probably wont use tbh.
Cheers.
