I'm pretty sure that 4.10 gears were standard in the 1500HD.

 

so i dont need two pumps? why would the kit be designed that way then?, what about two 044s one in tank and one inline just for a little extra

 

Its made that way so you dont have to take the tank out.

Put one in the tank and call it good. Having 18 pumps isnt going to do anything when you dont make enough power to max out one.

 

i would do a bosch pump in the tank, long tube headers, intake, pulley, and retune/ custom tune. those should help it purrrrrrr. might want to invest in a fuel pressure gauge first before u spend money on a new pump.


when you look at your radix's snout if there is a spacer inbetween the snout and the blower it is the 122. i also dont think the 112's have a radix sticker on the side of the blower like the 122's

 

Thde 112s have a little space in between the front cover and the case. Unless Im not understanding what youyr saying.

 

is there a spot on the fuel rail you can tie into and run a guage into the truck to see what the pressure is?

 

ya i guess i am wrong. the 112 does have a spacer.

 

Ya, I think you can run it off that spot where the black cover is in the picture Lance just posted. You'd have to take the core out of the schrader valve and then you should be able to get it there.

Someone correct me if Im wrong.

I knew because my friend got a polished 112 and that spacer wasnt polished, so it really stuck out. lol

 

Yes, this is correct.

 

Plus, 18 pumps would be a plumbing nightmare.
Not to mention, add a lot of weight.

Roger, I thought 3.73 was std. gear in 1500HD, & 4.10 was optional? Or was it 4.10 & the 4.56 was opt.'l? My sis-law had 1, but she got rid of that thirsty pig. Back then, IIRC, I checked just can't remember.

Lance, that Radix pic is pretty sweet in post #17!
