intank or inline fuel pump?
 

Dont know much about fuel pump setups. pros and cons on intank and inline pumps and thier applications would be nice. What about both?

Any input would be greatly appreciated:)


Thanks

The closer to the fuel the pump is, the easier it's job is, and the longer and more trouble free it's life will be.

A bit shorter than i expected, anything else?:)

P.S. Mr. WUD, i live that picture on your site with the fire hose going through the guys windows:D

What are you looking to do with these fuel pumps?

Mustangs come with in tank pumps that I believe were rated at 88 lph (sorry if I am stating the obvious for you...I am not familiar with what you may or may not know). Most people would consider this a weak spot in the Mustang, especially when modifying. I put in a 190 lph pump in mine....probably more than I need, but I can always use the pressure regulator to fix that.

LOL! Yeah, I'll bet he never parks in front of a fire hydrant again!

In tank pumps prime quicker, draw less amps, run cooler, last longer, and virtually eliminate any possibility of ever having vapor lock. Why? Because electric fuel pumps are much better at pushing than they are at pulling. The side of the pump that pulls the fuel creates a low pressure zone between it and the fuel, whereas the side of the pump that is pushed creates a high pressure zone, which eliminates the possibility of vapor lock. So, logic dictates that you want the pulling side to be as short as possible, and the pushing side to be the longest. You can't get much closer to the fuel than in the tank.

Hethj7 asks a good question: What are your intentions? That might make explaining things easier.

im going to upgrade my fuel pump soon probably t a 255. I under stand about intank pumps. i guess im really asking what the deal is with inline pumps, are they just a booster to make sure fuel pressure doesn't drop under load?

the inline pumps are for people with either blowers or big shots of nitrous that need the extra assurance and flow.

I see. Yeah, they're pretty much for power adders. For example, in the middle pic below, that thing w/ the NOS sticker on it at the front of the valve cover was my extra inline pump that I used for my NOS system. I didn't need it, my main pump was sufficient, but why chance it?

Take care,

Like we say in the Heavy Duty trade; Pumps don't suck, they push!:D

I have a 190 intank and have yet to install the T-rex. The 190 gives it plenty of pressure though I guess I'd have to have it dynoed or run it on the track to see if it makes any difference (with t-rex and without). I may be losing some up top without the t-rex but.. I dunno, it pulls pretty hard(the fuel pressure gauge in under the hood). Intank would be the way to go.
