There web site has two different part numbers tu432hp and tu434hp, it doesn't really say the difference, they are complete assemblies, do I need to wire anything on the fuel pump to, on injectors if my truck takes ev1 and I get ev1 I don't need anything else do I, I have searched around can't really find any info on the fuel pump modules, just didn't want buy anything a have to return it, my truck is 00 rcsb silverado with a whipple supercharger

 

What are you looking to do? You know you can change just the pump right? You will need a tune also. What injectors are you looking at? Did someone previously swap your wiring to EV1?

 

Get a little more power make run better, the guy that is going to tune it told me to get some Siemens deka 60 lb injectors ev1 or ev2 what ever may truck has and a 255 fuel pump so I thought I just get the whole module, truck runs rich and still has whipple electronics

 

Factory your truck should have multecII Injectors so they would require re wire or adapters if anyone is making them. I assume you plan to get rid of the whipple electronics? Changing out just the pump is not hard and much cheaper.

 

i googled the part number my truck has and it looks like an ev1 plug, the part number the gm book shows is 17113553 they list for 158.96, just not sure, yeah i am getting rid of the electronics, changing the pump does look easy just did want to take a chance of messing up the module

 

That injector is not a EV1, trucks did not come with a EVI. The part number you provided is a MultecII connector.

What are you goals for it? How hard to you wanna push it? This will determine what injectors you will need and what your options are. Unless it has changed, 43lb is the biggest multecII injector commonly available. Bigger then that and you will have to re wire or get adapters if anyone makes them yet.

Edit- Looks like racetronix makes a wiring adapter for the MultecII's to run a EV1 injector. I have EV1 style injectors but when I did my swap no one make a adapter plug so I just rewired all mine.

thank you for the help, i want to get some more hp, i dont race it so i dont think i will be pushing it to hard, i only made 312 rwhp the way it is know, its a side mount supercharger

 

Multec II 43lb injectors should work fine for you then, and they are a direct plug and play. Obviously a tune will be required.

 

deatswerks make a multec11 . 60 lb injector plug and play,i ran a set before I went to 80
