Lift pump questions
 
Ok so I'm pretty sure my lift pump is bad but I am not 100 percent sure but if I were to replace what would be better..... Getting another mechanical one or going with an electrical one. I turned up my afc a little bit and I didn't wanna do it too much in order not to hurt the transmission. I don't wanna do anything that will hurt it cause I don't have the money to just go get another one lol so I wanna knownthe benefits of both please let mr know! I just want a little more smoke and power.

you dont need electric one unless your doing serious fuel mods, rack plug, stix dv's
relavivaly stock engine mechanical one is just fine

Dude_57 07-06-2010 10:15 PM

thats true to an extent there are huge advantages to a nice electric pump. you get a nice fuel filter, a good water in fuel filter. if you ever have to bleed your fuel system its easy as a click of a button to fill the lines. plus you can get much better higher pressure with a good pump. i will never go to a mechanical pump again after having an airdog pump.

if your on a big budget a mechanical replacement will do just fine. but if you can afford the extra coin, youll be happy for a long time. plus all the name brand pumps have lifetime warranties

How wll the electrical lift pump affect my motor and tranny??

---AutoMerged DoublePost---

What do you think of the air dog 2?? Just trying to get all the info possible lol

jrad989 07-06-2010 11:02 PM

you may not NEED one but they are a great investment for reliability. i would almost pay just to not have to fudge around with the stock filter. and it wont affect your motor or tranny.

Dude_57 07-06-2010 11:09 PM

And yourtalking about the air dog 2 correct j rad?

jrad989 07-06-2010 11:20 PM

any of them. airdog fass all good products. they just bring the fuel from your tank to your injection pump. the injection pump is what actually delivers the fuel to your engine. you could have the worlds biggest lift pump but if you havent touched your p-pump you wont notice anything.

Dude_57 07-06-2010 11:28 PM

I thought the p pump was the lift pump?

jrad989 07-06-2010 11:35 PM

nope. p-pump is your injection pump. heres how the cycle works...
fuel in tank, lift pump draws fuel from tank to filter to injection pump. injection pump sends highly pressurized fuel down injector lines to injectors.
