Blue-chip pump cover!

Does the Blue-Chip pump cover look the same as the stock cover?

No it doesn't... although, it doesn't have to. You see, the Blue-Chip pump cover is a white/yellow/tan color... it's made of nylon... the OE Bosch VP44 pump cover appears to be a die-cast (metal) cover... the idea behind the Blue-Chip pump cover is that you reinstall the OE pump cover if you require injection pump warranty replacement. Since the Blue-Chip pump cover pierces the pump wire beneath the cover, the Dodge Tech. will not see the pierced wire... i. e. , no evidence, no problem.



However, let it be known (again), that was not my personal motivation to purchase the Blue-Chip pump cover. As I have virtually no real warranty left on my 100k warranty (I'm currently at 66k mi. ), my motivation was a superior pump connection... it was worth the cost of the cover for this alone. I have already made plans with Piers to acquire a new VP44 injection pump if required as a result of my Edge Comp upgrade. And if the weather gets too cold I'll have him install it in his HEATED shop.

EricBu12, a friend of mine has the earlier 3-wire Blue Box (up to 70% overfueling) and performed the same upgrade. Now, at the flip of a switch (or two, or all three) he can tune that bad boy to any task at hand.

pump cover

can anybody post some pix? i hate to be thick skulled, but i still don't understand how this works. i just looked at the wiring end of my pump which has a yellow "void" sticker on it. btw, i'm not sure what you would have to violate to break the sticker, anyway. it appears to me that there is a mutiwire plug that plugs into the end of the pump. is that not a plug, and the whole end is made with the wires integral? i'm embarassed to keep asking questions. this one, however, i don't understand.

redneckdr, the Blue-Chip replacement pump cover adds only two wires to what your existing 24v has...



it adds a positive 12v connection (red) which connects to the major fueling box wire (controls the fuel delivery solenoid) and a ground (black) wire which connects to the ground wire on the major fueling box. Both connections of the two aforementioned wires are made beneath the Blue-Chip pump cover via two set screws from above... the procedure was detailed in an earlier post on the first page of this thread. No existing wires on your 24v are changed, pierced or otherwise eliminated (where they can be seen).



Sorry I don't have a pic... I hope this explanation will suffice.

john, thanx for your reply. i need to see the replacement cover. i may not even be looking in the right place. basically i just don't know where the cover comes off, or what is replaced?? thanx again... .....

 

[John]

redneckdr, I'm somewhat unable to get a pic of the Blue-Chip replacement cover shot or posted right now however, the cover in question replaces the metal OE cover on top of the VP44. This can be viewed from the drivers side just below a large wiring harness... you should be able to see several of the Torx fasteners attaching the cover to the pump.



hope this helps

john, thanx again. i think that will help me figure it out. i've been looking at the back of the pump where the wiring harness "plugs" into the pump?? i'll look again tonite. even if i can't figure it out, i'll be too to ask again. thanx for your patience...

COOOOL!!!!! Now i understand. i was looking at the very back of the pump where the oem harness attaches, and couldn't figure out what was changed. sorry i was so thick headed.

thanx again, for your patience, and the pix.

thanks for taking the time

great pictures -jon-

It's a pretty trick little cover, well worth the $50 for the ease of connecting to the pump wire. Lord only knows what John's doing to his to BOMB it -- probably having the inside rhino-lined, the outside powder coated, and little neon lights mounted to the sides.

Thanks for the pics jon. In you guys opinion, would this be as good a connection as soldering into the pump wire? I'm going to be like John, and figure my warranty gone soon, so just want the best possible connection.

Thanks, Doug

 

[pnwradar]

I would think that soldering into the pump wire would be the best connection, both physically and electrically sound as possible. It looks like it'd be tricky to get properly soldered, without removing the wire loom from the hood area, and a bad solder connection will be nothing but trouble. Soldering would preclude easily removing the connection for any testing. The tap that this cover makes is weather-protected, being inside the housing of the pump controller, and IMO is better than the crimp-tap or the needle-tap method. The wiring connections are weather-resistant crimp connectors, the pump wire tap one mated the COMP connector, the ground wire from the COMP was a crimped ring, easily replaced with the proper crimp connector.

Good point about ease of trouble shooting. Looks like I need to get one on order! Thanks, Doug

soldering in

if one could get to the pump wire to solder a connection, you could simply solder a short "pigtail" with a push connector on the end to connect to the fueling box. that way, the box could be unplugged easily for trouble shooting etc. if i ever connect a box to the pump, that may still be the way i go???

great pics and description ... DC is also thinking the same thing as me and they thank you for the assistance .

 

[Bob Wagner]

The cover is only for better wire connections, there is no beating DC



Remember the <b>ECM</b>never lies and Is always in DC's favor anyway.
