Point taken with the fail safe. Actually the petroleum is my back up plan. the car is being built for cng this ****ty gas IS my back up plan.

I agree. First pump off the stock control unit. Second pump hobbs switch directly off battery. That sounds good to me. Then I'm only pulling 11.7ish amps for single dw200 pump.

Any way you can use the actual FSM to draw your diagram? It will be easier to understand for me at least.

Quick question hope this a ok place to post. I have id1000 and a walbro 465 e85 pump that I wired with a dw hardwire kit to run 100% as per the directions on the kit. The pump and the relay are grounded to the chassis so the pump runs all the time when the ignition is on, This really helped my flow but I wanted to keep my idc down more so I got a fuelab fpr and installed it today.
I set it as per instructions but it seems I cant get the base pressure lower then 50psi. With the fpr on the loosest setting with the key turned on but not started she reads around 45psi but as soon as I turn the car on she goes rite to 50 ish. Even if the vac line is hooked up or not it still reads 50. I thought when it was in vac it should go lower? Is it just that the pump is flowing so much that it cant go lower? Wither way it seems to be fine as I was going to up my base pressure to around 50-55 anyway and she runs normal. It actually idles a lot nicer and is not running rich as I assume my oem was getting over run by this pressure when I hard wired the pump.

It's because of the insane amount of fuel that your pump is flowing, no way around that unless you do two smaller pumps and run one on a Hobbs switch, or get an fpc which is the right thing to do.

I am thinking of hooking the pump ground back to the fpc instead of to the chassis to regain the duty cycles. I guess it is a gamble its either going to fry the fpc or I am going to fry the pump by leaving it 100%. Any one still using the fpc on a large pump like this?

Nate, check out my wiring. I drew it up in a way that will retain duty cycles and not kill your FPC

The pressure is caused by the return line within the fuel pump assembly. I modified one before and it allowed me to drop the pressure but then I had issues w sucking the assembly dry.

Well I just put the ground back to the fpc instead of leaving it grounded to the chassis and it seems to be much better. It primes and shuts off and I dialed it down to 43.5 base pressure and as soon as I put the vac line on it went down into the 30's like it should. I will turn it up when I get my tune to lower my idc. It also seems to idle a lot more smooth instead of a hunting idle when it was 100%.

Not till I tune for it I plan on bumping the pressure to 55. I am not too worried my friends 2012 sti is running it this way with the same exact setup as me that is what finally convinced me to do it also Manitou is running it the same way on his high hp build. Why what do you think will happen when I go wot?

Ok. Yes tune first. Your not going to get the full flow but it will be better than nothing.

Yes I figured it will be less but I just did not like the fact that I could not really adjust the pressure with the pump at 100%. Also the is a dd and I cant really afford to change the pump out every 6 months. Has any one had to replace there 465 yet or is it to soon to have them fail from 100% duty?

No unless you try wiring like the guy who is in Subaru school is saying to do. But no one has tried it yet. Ground to FPC controls the amps. You want amps not volts to get the pump to flow.

Should I just go back to 100% then until I get something like the fuelpro?

Fuel pro was easy to install if you have soldered etc before.

It is up to you on what you want to do. Full flow is full benefit but premature failure is possible. Stock FPC controlled is less flow but will last longer. I think these pumps are rated for 3,000-5,000 hrs of operation. Check walbro's website. I'm not sure if that is 100% or varied operation.

Well it seems to be working ok she is running great at idle and I thought I would just see what happens at wot for sec and it was fine. It was rich around 10.8 but I was happy it operated fine and will be tuned next week. The only issue was when the fueling was going into open loop it was pegging rich during heavy cruise when fp duty would switch from 67 to 100% back and forth which will be tuned for as well since it was currently on a tune for 100% only so I am happy.

Glad to hear you guys find the FuelPro installation easy. It will maintain your pump longevity while not compromise on performance. We brought this product to market because we saw so many instances of bypassing the FPC causing pumps to fail prematurely.

Kind regards,

I just finished my dual pumps. I will try to take some pictures tonight. Both pumps 12g wire with 15a inline fuses.

Pump 1 relay with signal wire from PCM ground from pump to ground from PCM. I did that becuase I had to cut all the wires from the stock harness. 2 wires control red(orange) fuel low light. 2 wires control float. The last 2 were power and ground to the FP. I am using the power to control the relay I didn't want to just leave the ground hanging out solo so I tied it into the ground of the pump.

Pump 2 hard wire to battery and hobbs 15 psi switch on the chasis ground.

QUESTION.
I mounted the relay on top of the pump housing under the trunk cover. Will this get too hot in there? it made for a clean install.

I am so close to finishing this build. I can't be happier with how things are going and turning out. super clean and super sexy.

You think it's ok to keep my relay where I have it????


here is my battery setup so far.


4g to the starter from battery (~6')
8g from starter to fuse box (~3')
12g to each FP (~5')
4g ground from battery with switch (~1')
6g ground from block to stock location (~3')

You think I need to install a 4g ground from block back to the battery????

Hey guys I know it has been ages but I've finally got around to installing my walbro 460 e85 pump and did the hardwire per my instruction/post earlier and so far so good. Granted, it's only been a day but I can keep updating. As far as I can tell the duty cycles are still enabled and I have no CEL's. Also it does not appear to be overrunning my Stock FPR. AFRs appear to be unchanged as well. If they are it's negligible.
