I was wondering at what point in the mods should i think about adding a auxilary lift pump to keep the cp3 fed?

 

Now............

 

X2!

Mine was pulling the fuel pressure down to 0 with just a Smarty on #5 (90hp). The Holley cured that.

 

I'd say as soon as you install a power adder you will benefit from a better lift pump. The factory pump is barely adequate for stock power.

 

should be the first thing on the list that way you can realy use the power adder you chose

 

Okay, I'm in the same boat.
My triple dog will drain my FP to "0" when I really tromp on it, is this going to hurt things if I kept doing it or would I be okay as long asd I'm not going crazy all the time?

The BDTD, the boost fooler, air cleaner can all come off if I ever have to take it to the dealer, what would they say when they see this big after market pump hanging off the frame on a stock truck? Would that not be a give-away I''ve been "tinkering"?

Also, what are the most economical pumps to add? I doubt I'll add much more power than what I've done so far, I don't think I need tons of fuel pressure but I don't mind paying more for better quality.


JR, I've read lots about Glacier pumps, what can you tell me about your Holley?
Is there any additional pump I can use where I won't hafta drop the tank to install a new pickup?

 

i like the fass kind of expensive some say loud but the water sep and filter on it is worth it to me and i have taken my to the deal and they dont seem to care about the lift pump since one they cant void a warr. unless they can prove its the fault and a fuel pump you cant say is the cause of a rod throw you know.

 

I have the B D Aux. kit, a little less money.

Al, what kinda pressure does that one put out and do you need to install a new pickup?
It is a lot cheaper than the Glacier kits...

 

I think that BD kit just splices into your factory fuel line. If your lift pump ever goes out, you still have a problem because fuel will not flow through the factory pump up to the BD pump correctly. At least that's what I was told.

Personally, I think that you need a lift pump before you start putting on chips/programmers. The reason I say this is because my truck will/would drain the CP3 down to 0 psi with a stock tune. Put on a power adder and it drains it quickly in no time. I tried to talk to a dealer about the fuel problems (when I was stock) but they were of no help. They said the pressure means nothing; tests are made on volume. I understand that, but 0 psi is not good on a stock truck any way you look at it.

As for which one, I like the Glacier because of the Walbro pump. They aren't very expensive and can be replaced easily if the need be. On the FASS, if it goes out you've got a problem. Both are good kits though. Not too many ever fail.

IMO....... you need a lift pump/fuel system NOW!
