Auto and Manual Pumps

[ashby]

What are the differences in the automatic and manual pumps?

Horsepower. Timing retard on the 887 and 913 pumps

Depends on the year. Ranged from 160-215hp. Auto also has a TPS mounting on the side of it, to control the trans.

Delivery valves, cams, plunger/barrels. The 215hp 913 pump has plungers with a double helix. They can move the fuel! They were on the '96-'98.4 Rams w/ manual trans.

160 and 175 pumps are the exact same besides the plates
-they have 131 delivery valves

180 pumps have 181 delivery valves and diff helix's then the 160/175
- have better cams then the 160/175 that will have better fill time

215 pumps have 181 delivery valves and an upper helix that will flow more but retard timing after 13mm of rack travel
-215's also have lighter govenor assemblys
-same cam as 180's

160 came in 94-95 autos
175 came in 94-95 manuals
180 came in 96-98.5 autos
215 came in 96-98.5 manuals

you can exchange any of the pumps
