The spray is conical spray with a fog in the center at 4 inches from tip. - 2000 with calibration oil, Think it was 2300 when testing with diesel fuel.
If it does not drip at 1700, its considered good - at least thats what the old book said.

This is a cutaway WD45Diesel head of David Ferguson's we had under the tent at Hutchinson. We had it hooked to a tester and got the camera to snap at the right time. |

It's amazing those old diesels ever ran why without any valves, and most of the fuel going out the other side of the head?! :) ------------- Still in use: HD7 WC C CA WD 2-WD45 WD45LP WD45D D14 3-D17 D17LP 2-D19D D19LP 190XTD 190XTLP 720 D21 220 7020 7030 7040 7045 3-7060 Projects: 3-U UC 2-G 2-B 2-C CA 7-WC RC WDLP WF D14 D21 210 7045 N7 |

| Tom, thats kind of what it does look like, but the ones I checked would chatter as pressure was built up, the spray you have looks like a hard handle push to get the time long enough to snap the picture. ... But that pic is still way cool, I really like it. |

| ive always wondered what it looked like, we just did my dads 45 diesel injectors they all tested around 2100 to 2200 psi with new tips |

| That is lots more fuel than a running tractor would use on one injection for sure. We took several tries to get that picture, it was fun when we got one to turn out. Thanks. Tom |
