We are going to give a 190 a fuel system upgrade. Can I just install 7080 nozzles seems the best bang for your buck. Going to have fuel pump reworked and set as high as it will go also and see what happens. Gary

For what you want to do, you don't need bigger lines. Only time you will need bigger lines is when you have around 500cc of fuel or more. You'll be lucky to get 150cc from the stock pump. 7080 tips with the leaf spring screwed all the way in will net a very fun tractor.

Ive also been scouring for some 7080 nozzles to do the same thing but one thing I'm unsure of is the 7080s had 2 styles a Bosch and an Allis Chalmers. Which style will fit correctly and who has some?

7080 and 7580 are the same injector tip with four .0148" holes.

FYI, when someone says use 7080 nozzles(4035509), they are referring to the AC injectors. Like Dr said, they are the largest hole nozzle used on a 426, so it's a fairly low cost "upgrade" when cranking the power up. They are not nearly large enough for big pumps though. Those still require EDM work. But I don't use the larger, more expensive nozzle for that, I use the lower priced nozzle that has smaller holes(4035508). The American Bosch injectors have slightly smaller holes at .014" (.36mm)

new .450 two plunger heads are now available, add extra charge ports. remove transfer pump & float the rotor with end play bolt at front with no spring. add external pump. set at 150psi + for more power. use a none speed advance 0 degree housing, open up the fuel return flow back to the tank, to lower the case psi. find a set of 5 hole .020 dual feed boosh injectors, with re-registered hold down plates, & return line kit. hard to find but they are around.

Why would a .45 2 roller pump put out more than a 4 roller .35 roosa? I know Ed puts out some high flow 45 heads, and maybe he could explain - MANY years ago we built some of the as described above 'floating head roosas' and found the 45 heads put out more smoke but the 4 roller seemed to put the fuel in quicker and had more 'torque' feel. would be interested in the discussion... When we exited the pulling scene everyone went to the P pumps. We had a DM 4 roller built with double key shaft and gear with larger than .35 plungers and an enhanced cam ring -no transfer pump as used aux feed pump - no delivery valve - now the good part, it was never used as the puller put on an inline - melted the pistons, bent the rods, and sold the tractor to a guy in New York-we put it on the shelf - and it disappeared... the end of the aluminum part # tag had 'exp' stamped into it , it was painted black over the , maroon ...
so if anyone ever sees....

The biggest 4 plunger DC is .310, so anything bigger was custom made. I've got several .310 DC pumps out there running down the track, and they do deliver a lot of fuel when I make my mods, but the .450 DB still out flows them. I don't do the external transfer pump, I leave the factory one in there, but I do make mods to it. My pullng pumps are very reliable, and make lots of power. I don't modify the head at all though.

The original reason for taking out the transfer pump was to assist in unloading the pump shafts where the thin place is as well as filling the plungers completely at higher rpms. The pressure of 135-150 psi caused the pump shaft to walk forward - thus there had to be a thrust bolt put in the front cover to replace the spring loaded thrust button. Removing the delivery valve at this high pressure also yielded a few extra cc's. I was talking to one of the old guys who works here and he thinks we took the .37 2 roller plungers and put them in the .31 head leaving the shorties as is. Think we left out 4 of the weights as well. I also think we used the v slot metering valve instead of the later one. Just thoughts on a rainy day...memory aint what it used to be...
