Don't know much about them but Bosc has 181s and 191s. I believe that the 181's are on the 215 hp pumps. Joe D stated in article in theTDR mag(or was it a thread) that 191's didn't deliver much more fuel than 181's.

There are other ones out their though.

The 181s are what I used for 800 HP, single turbo, diesel only. I tried 191, brand new, several times and gained 0. 0 HP with the 215 HP pump, and lost about 12 HP with the big 13 mm barrel pump. I have a new set of 181s if someone needs them.

Yes the 181's would help out. They would get more fuel to the 370's. A good 215hp pump would be nice with 181's would be nice but you have your pump set up pretty good.
