FEED ME! Fuel Pump Wiring Upgrade w/ Hangar Mod ALL Modified Fox Body Mustangs

[@adamcartwright6220]

I still really like these older informational format videos! I’m about to do the Aeromotive 340lph pump on my 92 GT this weekend. Thank you for the video!

[@christerzian9293]

Neo, this video saved me. Just installed a 340lph pump and have the upgraded wiring kit but was a bit lost on how to wire it in without replacing the top hat. If all I have to do is modify the top hat, I’m happy. Thanks.

[@Neomustangs]

That’s great news !

[@LamborghiniX09]

I'm super grateful for this video Neo! This resolved my fuel pressure drop I was having with anything over 8PSI on my Turbo 347 with a walbro 400. Fuel Pressure would drop into low 40s before and after the upgrade I'm sitting at a solid 55PSI at 11# of boost.

[@jimmyprater7546]

Thanks for the excellent video, just ran 10 ga marine grade to the pump terminals. My battery is in the trunk just forward of the fuel pump wiring, easy fix.

[@jimmyprater7546]

FYI, the SVO FP relay is under the drivers seat.

What pump is that part # all the aeromotive pumps are pre wired with 16 gauge wire. No way to wire it up like you did. Plz help lol.

[@joshuaanderson8869]

Talk about good timing to watch this video. Just installed my turbo and got my 340 fuel pump in the mail. Now I got to go get some 10 guage wire. Thanks for this video. I know it's an old one but it still good information. 👍

[@Neomustangs]

Yes sir

What is the part number for the pump ? Bought the Aeromotive pump and heavy wiring kit and the pump is pre wired with 16 gauge wires lol does not have the male to female connections for the wires to run 10 gauge wires.

[@Neomustangs]

Thx!

[@ReyesBuilt]

You think I could wire a boost a pump inline pin 87 and it would effectively give the pump more power if needed?

[@Neomustangs]

why use a boost a pump? I dont think i would use it. If you don't have the sufficient fuel flow you should ramp up the fuel system. Boost a pump for whatever reason dont work it will send the tune lean which is not good.

[@ReyesBuilt]

@@Neomustangs kinda in a dilemma. I’m coyote swapping my 96.. I have a 340 lph pump which would be more than enough for the coyote N/a. I also already bought a gen 2 tvs blower for it. I’d like to play around on pump gas 10 psi of boost, I don’t think the 340 will be sufficient enough, trying to get data for the average joe who may not want more than 600whp and don’t or can’t use e85. Want to see what the car will do before we add a complete return style fuel system from fore and e85 and turn it up.

[@ReyesBuilt]

@@Neomustangs some roush kits come with baps and offer a warranty btw. I think it should be fine if wired correctly. It just supplies a static 18 volts to the pump spinning the pump a little faster. Only thing is I’ve never seen anyone from 86-98 use one

[@mcb98]

Thanks for posting the video. I just installed a turbo on my foxbody. Above 4K getting into boost the car goes super lean. Today I did this wire mod on my walbro 255. Tomorrow I’ll test it and see if it solves my problem.

[@6spd85notch]

I’m actually having some fuel issues now. I’m running a stock tank with a sump in my 85 347 carb setup using a holley blue dead headed. Pump is on the steel bumper about an inch above the sump. All of a sudden about 1k miles later the pump won’t prime with less than about 4-5 gallons In the tank Basically I have to run a half tank of gas minimum. -About a foot of10an to the filter and pump then -8an to the front. I’m debating using a fuel injection tank and figuring out how to regulate it down to 6.5 psi for the carb. Or a fuel cell In the spare tire well ?? I changed the pump cleaned the filters and it’s all new stainless fuel line. Any ideas or help would be great.

[@davidmondragon7616]

What's up Neo. Have a question man! Do you know what can cause fuel pressure drop at wot after car has been driven for an hr or so. First 30min of drive car is fine at wot. New fuel lines 8 feed and 6 return. Second new pump 525 holley. New fuel regulator. 80# injectors. Fuel relay kit straight to pump. Voltage at wot at pump is 13.4... fuel filter is hot to the touch and it's not near any heat. Scratching my head on this one.

They sell those aeromotive pumps today hardwired and you can't change the wires and they look thinner is that a problem especially to fuse it at 30A if that wiring on the pump looks like 16awg

[@Eddie510s]

Neo what if the 340 Aeromotive pump itself has its own wire coming out of it ? I’m assuming I purchased the newer style . Thats where I’m stuck at right now . :(

[@Neomustangs]

probably would go with a pump that you can plug into not one with solid wire coming out of.

[@stang140mph3]

Thank you for the video just did the mod. 2 quick questions. The air line that normally goes from throttle body to filler tube do you block it off?? And do you have a video on modifying driver valve cover for breather?? Happy Easter to you and your family!!! Thanks again!!

[@Neomustangs]

That is correct. The mod on the drivers valve cover should be done at the end of the valve cover itself. SO it clears intake upper.

[@ilike9s]

[@joshuaanderson8869]

I have a two question hopefully you can help me out. I wired my 90 fox like you did in the video but when I key on the car I get nothing from the pump. I can hook 12v right to it and it pumps. Is the pink w/black stripe the trigger right. Also if I'm installing holly terminator do I not mess with there green fuel wire and just stay how you did this car. Thanks. Sorry for long comment.

[@Neomustangs]

Holley would just wire right to your relay.

[@joshuaanderson8869]

So my green trigger wire from the holly would wire back to the 40 amp relay that goes to the upgraded fuel pump stuff.

[@brokentoolgarage]

Awesome, thank you. I just installed a Walbro 255. Looks like the fuel pump wiring is a future mod. I was just wondering why not drill the stock stuff out when you decided to do that. On connectors - I used the heat shrink connectors.

[@mitchescobar1060]

$2000 worth of information..!!! With the new wiring kit they now have for available..!! One question do you need a return style regulator to make this work??

[@turboman351w3]

so no wires go to the ecu, its just wired in direct to the battery and relay and then to the pink and black wire to signal on the pump????

[@Neomustangs]

Yep. I would prefer it go to the back of the alternator but for the sake of running the wire somewhere I don’t want it I’m just gonna run it to the four gauge that goes to the back of the alternator. I haven’t ran that wire yet but I explained that

[@novi306]

do you not extend your return line to prevent aeration so the pump isn't pulling air along with fuel?

[@Neomustangs]

Yes you could if you wanted to. I should have mentioned that. I didn’t really see much aeriation on the stock hangar style pumps. But its not a bad thing. Problem is the basket inside the tank it’s hard to get that line right

If I just vent my tank like you did, I don't need that vaper canister under the hood right?

[@TheNote408]

I bought the aeromotive stealth 340 fuel pump but there is a pigtail that is molded into the top of the fuel with 16 gauge wire seems the only way to do that mod would be to cut the 16ga wires and solder them to the 10ga but that doesn't make sense did they redesign the top of the fuel pump although there are two little silver what looks to be positive and negative females where you can plug a male bullet connector into each one but they're very shallow so I don't see that working any suggestions.

[@Neomustangs]

I made a video on how to modify your hangar and run a relay it’s a long video.

[@TheNote408]

Yes I watched it from start to finish...the top of your 340 pump is different than mine my 16-gauge wires are molded into the top of the pump the plug is not at the pump there is a 5-inch pigtail that comes out of the pump with 16 gauge wire it appears your plug is at the pump head mine is not...must have changed it doesn't make sense to solder 10ga to 16ga coming out of the pump does it?

[@Neomustangs]

Ya I had to deal with one of those pumps too. Didn’t like it. Used a different one I could feed direct 10 to

I installed the terminator x in February and i have the pump drive wire from under the passenger seat ran 10gauge into the trunk to the realy. The battery is in the trunk also. I wanted to run the 10 gauge from the pump out of the tank and didnt even think to pull off the factory connector peice...looks like im dropping the tank again lol thanks for the information!!!

[@Neomustangs]

Yw !

[@Bobby4v]

I went ahead and went the easy route and bought the aeromotive fuel pump wire upgrade kit. Yes its over priced and i could have made it myself alot cheaper, but it is a nice harness. Today i installed it. I drilled out the connector like you did and open the holes slightly with a stepper drill. Everything worked like a charm. If anyone is doubting this mod or dont think its worth the hassle, it is very much worth it! My car with the 340 stealth pump, holley 48lb injectors was dropping fuel pressure from 67pounds at 5100rpm 6.5 psi boost to 36 to 40 pounds of fuel and 7.8 ish psi boost at 5500. Duty cycles were 100% to 110%. These 48s shouldnt have been nowhere near 100% on my set up. So after i finished the 10 gauge wire upgrade i did a data log and wow!!! At 6,000 rpm my fuel pressure was 60psi at 8.0 psi boost with 84% injector duty cycle. The rest of my fuel system is stock 1993 5.0..thanks again man! This shit works!!!! Lol

Do you use any specific wire safe for submerging in fuel and without termination at the hanger hat is there a chance of fuel wicking up the wire I am planning to upgrade my wiring and seen people debating on this some people say they have had no problems others said it's a ticking time bomb I'm leaning towards termination and fuel safe wire I'm sure it gets blown out of proportion though.

[@Neomustangs]

I wouldn't worry about the wires. I have ran this mod in many cars for years. I secure the wires to the hangar they don't move at all. What would be the difference with wires submerged with a cannon plug attached to the pump? They would still get exposed? Nah youll be fine.
