Default Fuel Pump.....

I keep hearing and reading different stories about a fuel pump. Some say yes you need it, some say no, some are like "If you want it can't hurt.". Well, this is HMT and I'm not into spending money on something that isn't needed. I would figure it would more or less depend on the set-up of the vehicle. Any comments or opinions are welcome guys! Thanks!

Not needed for a mild setup. Good insurance though. I personally run a Wlabro 255. Only cause I got it free though.

On my old setup I had a MSD inline pump. When I built the new motor and went to TurboEdit I just left the inline pump in there because everybody said it was good to be on the "safe side", you don't want to run out of fuel. I have had some problems with the car(all my fault for trying to tune without a WB ) so I finally orderd a LM-1 WB and next week I will be tuning it the right way. In the meantime while I am waiting for the WB I thought I would try taking the inline pump out, it makes WAY too much noise and maybe it is part of the reason that the car runs to rich. Well I have been driving for about a week without the inline pump and the car runs alot better. We will see how it goes when I start tuning the car. Right I am not pushing it to hard because I am just running a base map.

Well ya see, I found a decent deal on a Wlabro Inline Fuel Pump (since its inline it should be easy, right) and I asked what model # and all and he hasn't gotten back to me yet. I plan on running 8 psi on a .42/.48 T3. So will I be alright and just upgrade later down the road for more boost? How much can stock handle anyway? Thanks!

You dont want an inline. You want a hi flow in tank. Not high pressure inline.

Thanks. I think I'll start out with stock since my set-up is "mild".

Hmmm, would the 255lph-HP in-tank unit be bad also?

think about it a stock fuel pump is 190lph, liters per hour, and a 255lph walbro is 65lph more than stock. i personally have a walbro. its been in my car for about a year. im on 8-10lbs stock z6 with uberdata and 450's in a 91 hb converted to obd1. my car runs really good for what it is and what i have in it. no the walbro isnt a bad thing, if it was bad everybody wouldnt run them. my .02
