need some ideas. replacing injection pump
 

Dad wants to go back with a hott rod pump. Already have a fass system. Is there any ideas on what else to change? Thanks?

What else to change as far as what? just go s.o vp

I hes already ordered the pump. But as far as replacing. Is there any electronics you hace to replace? Also is there anything that has to be readjusted?

Nope, all the pumps electronics are already in it. But you will need the puller to get the pump off the gear.

Ok thanks for the heads up. Now, what about takin the pump out and back in. I know the gear has to be on 12' o'clock. Any other advice

yeah make sure the keyway is facing 12:00 like you said is important, the nut between the pump and the block is fun :D but other then that it's all fairly easy stuff, once you get all the sh!t moved out of your way :tu:

Thanks for the advice!! :tu:

Why did you choose the HRVP? If you have a good chip on the truck you are not going to gain anything with it except spending more money for it..

I bought the puller for the pump gear. but the cheap steering wheel puller worked fine for me, when I was in a pinch. only real reason to keep the keyway at 12:00 is so the key doesn't fall into the timing gear. alot of extra work to get it if it fell inside. what I did on mine was ping punch the key so it flared out some. That way its fits snuggly into the keyway on the pump. You would have to really knock into something pretty hard to have knocked it out during installation.

The reason he went with a HRVP, bc he wanted the extra power and everyone around town kinda push him into. But hes got that, a edge juice with attitude and 90hp injectors. I need to test the injectiors. Also does the hvrp have any fuel milage?
