what size line do you use for the feed and the return? do you use two fuel filters? one before the pump and one after?
thanks

turbostreetfighter

use -8 lines after and -10 before (if you have tha room) also run a filter before and after. i have 7 of those pumps in my shop that have been screwed up by customers that only ran a filter after the pump. if ANY contaminates get into the pump it is history!!

good luck!

so -10 for pick up and -8 for return? are you running two feet and two return ? i'm trying to figure out the best way to run it. I have 850 primaray and 1600 secondary with rail. the alumium filter is before and the paper is after right? do you have any picturs of the pump mounting location and the regulator?
thanks

I can understand running a filter before the pump so it doesnt get trash but why would you need on after the pump? The fuel should be clean, the pump doesnt enter anything into the system does it? Is it nessesary or just a "overkill is best" kinda things?

Dont get me wrong I'm down for extra saftey I'm just wondering if its actually needed for some reason besides saftey

i believe that's what aeromotive say to run on their pump. you need two filters, one before which is the alumium filter, and one after, the paper filter. i think it's just a saftey issue here. you don't want crap get into your fuel line and injectors, it could done a lot of damge.

loi,
Where are you going to mount your pump at? I just bought one also and that thing is HUGE! I haven't figured out where I am going to put it... Also, how are you going to run your fuel pick up? I was thinking about having a fitting put in the bottom of my tank and trying to mount the pump somewhere in front of the left axle... it looks like there is some space there.

the pump doesn't have to work as hard on sucking the fuel out of the tank. I'm not sure how and where to run the pick up yet. i need to look under to see. here is the link to my stang ,got a pictures of the pump and filters under the car, although my fuel were sumped.

i am running the stock pump in the tank still and it feeds the small 3 liter tank that the aeromotive pump feeds out off. and the return from the engine also goes into the small tank and then in to the factory tank. running -8 line for supply and-6 return. the fuel is still being filtered as it is drawn out of the tank by the filter on the end of the fuel pump.

loi

The small tank you're talking about is the one with the 3 stainless line connected to it on the pictures? what are you using for filtration? i do see a fliter anywhere ? btw, nice looking FD

Is it legal in most race classes to have the pump in the car like that? For some reason I thought they had to be mounted in the tank or outside somewhere.

sokudo

in japan there is no such rules. there is a filter after the pump and like i said there is one in the tank

SupraTurbo

to be nhra legal, the line and the pump has to be outside of the car. maybe like he say, japan is different, i will worry too to have the pump inside the car lol

now is it necessary to run a return line back into the tank? I know that this can possibly effect uel pressures, but for ultimate perormance, does it matter?

Going back to that filtration issue. I'd run a suction screen type filter before the pump that you can take a part and clean. After the pump I'd run one of those 10 micron filters. Reason you do not want the 10 micron filter before the pump is cavitation, if that filter ever "plugs" up it will trash your pump as fast as contamination will. But with a suction screen style filter it will keep the "nuts and bolts" from entering the pump with out drawing a vacume.

I think turbostreetfighter meant to use -10 lines from the tank to the pump and -8 from the pump to the rail. You want the larger line to be on the suction side.

it will effect the fuel pump. with no return it is as if the pump is pushing againt a wall and that will effect how hard the pump has to work. with a return the pump just circulates the fuel and doesnt work as hard.
