With a drag turbo, would it be safe to remove the inline fuel pump and upgrade the intank fuel pump? I defaintely don't like the idea of having the fuel pump in the engine bay. So if I wanted to remove the inline fuel pump, what kind of intank fuel pump would I get that could pump enough fuel for the turbo?

 

Keep the inline pump, you'll lean out with the intank. There is nothing wrong with having the pump in the engine bay.

What would be the best location for the inline pump and best power source?

TIA

 

FYI,

Im running rich at 10 to 12 psi with an intank 255 and vortech 10:1 with stock injectors...

255lph intank is the way to go.

 

Yeah, on a GReddy turbo... not a drag...

 

Best place for an inline pump is right after the fuel tank. But get ready to hear a buzzzzzzzzz.

 

oh, gotcha.

 

get a holley 255lph intank.. that will do you good

 

If your running standalone or regular fuel pressures(30-50), an 255lph in-tank is also the way to go.

 

Dustin, just forget about it, I dont even try anymore. Hop on the intank bandwagon. Everyone throw away your inline Bosch and Airtex pumps and put in a Walbro 255lph intank pump.

 

I remember there was a site that sold walbro pumps for like 120 or less.

Which in-tank pump would I get for my 90-93 integra?
Would it be the 92-95 civic?

 

hahahaha, yeah, thats it, join the cause!! heheh
switch over to the inside....hahahaha

 

On a serious note I just bought an MSD inline opump and want to install it tomorrow. Please give me tips not sarcasm.....TIA

 

Sorry but Walbro is a piece of **** compared to the bosch,throw that away,the bosch flow's 300lph or 370lph depending on which one you get,get the shortened ENDYN bosch made to fit intank,it flows 300lph

 

Yes, reading the endyn site really makes you a believer in everything they say. Just because Bosch pumps are fat doesnt mean walbros is a piece of ****.
I seen 400+ hp cars with a walbro and work fine.
The only thing more I see in the bosch pump is the size and cost.

 

You should check into the spec's of those pumps a little harder and youll see one thing more..and whats the most important part...300lph...IT FLOWS MORE

 

Seriously keep the inline untill you go stand alone. TurboInteg95, dont worry Im with you. Thats why I have purchased 2 Bosch pumps from you because they work so well.

Maybe you should read what you actually see instead of reading what you want.
yes it flows more i know that. bosch pumps are good and all but for half the price I would just get walbro eventhough it doesnt flow more, it flows enough.

If your running an fmu, have an in-line pump.

yeah, i was being fasicious, if thats how you spell it. I just dont understand this Walbro nonsense. It says right on the box that it quits at about 90 psi. In an aplpication where you are using a standalone the walbro is definitely the way to go. It can supply plenty of volume. It's just that when it comes to pressure, it cant hang. i was just telling Dustin awhile back that I'm not even going to bother trying to tell people about the whole pressue thing.

 

Yeah, what we have here are a bunch of misinformed people, dead set on assisting their misinformation to spread like the plague. Brian I have joined the club, no more trying to tell people the truth. Telling them what they want to hear is so much easier and will waste less of my time.

Correct me if Im wrong but cant the inline pump only supply as much fuel as the stock intank pump allows?

 

I believe the inline would just pull fuel through the stocker intank. Some people take out the stocker.

 

See, people have a misunderstanding between pressure and flow. The stock fuel pump can flow more than enough fuel for these people with low boost turbo setups. However, with a vortech 12:1 FMU, it /cannot/ provide that flow at high enough /pressure/. Pressure and flow are inversely related. Aka, as flow increases, pressure drops for the same volume. And if pressure increases, flow drops for the same volume. Now, you install an /inline/ high pressure pump right before the fuel rail. The stock pump now only must maintain around 20psi of pressure (I have measured w/ a fp gauge) and flows quite a bit to supply the inline pump with fuel. The inline pump then builds pressure between itself and the fuel rail (where we need it). This way, the pump only has to pressurize the line between the inline pump and the fuel rail, instead of all the way from the tank to the fuel rail (less pressure drop). It all works rather well.

Difference.. NOISE... no thanks on the inline, I'll keep my 255 walbro hp intank.
