Engine/Transmission (1994 - 1998) Which Fuel Plate?

[MRasmussen]

I have a 98 12 valve and the guy that owned it before me said that he had a fuel plate put into it. I was wondering if there was an easy way to check which one it was or how to change it. new to this so everything helps, thanks.

You should try to ask the prievious owner. They are easy to change. Just make sure you mark the position of where the plate is now. If its in the stock position.

 

[KingS]

it should have a number on it unless he made it him self

I too have a 98 12 valver. So far I have had two different fpps put in. The original one plus the two from TST. First I went by the TST chart and put in a #8. Then some Cummins guru said I could use a #6 for more power while towing. I "think" that the lower the number the more fuel it'll dump. Changing it out is a piece of cake, getting it right is a PITA.

Why is it that some places say depending on your year and transmission the same plate has different #?

 

[bmoeller]

Because of differences in the stock power levels, and different fuel injection pump setups. The '96-98. 4 215hp trucks with a manual transmission move the most fuel, at a given setting, than do the early 160 and 175hp trucks.

A 10 plate in my 180hp pump is rated at ~220hp, but the 215 pump will be ~330hp.

When adjusting the cam plate forward for more power, Forward means toward the front of the truck right?

 

[Forrest Nearing]

yes... forward

94-98. 5 automatic or 5 speed. . #10 plate. Mark your stock location and move the plate toward the firewall 75k or so. Automatics will live and it wont slip the clutch. I have done lots of them this way. Once they have done their transmission or clutch then just slide it forward some. .
