might seem a little cheesy but they work just fine


i tend to use manufacturer specs as a baseline but never as a bible, it's always good to know exactly how much current is flowing through a circuit. IME pumps always pull more amps when they are run beyond 75% load and the fuel will warm the pump and push the amperage higher, bench testing a pump in a static environment will always yield less draw and higher flow. this is also why most pumps that i have run near maximum rating died while on the dyno.

 

More details on this hose?

Thanks.


Howard, glad to hear the motor is still good to go. I think that what you said about still having some stock rubber line on the fuelt return could be your culprit.

Hope you get it sorted, really anxious to see what the 9180 does with 85.

 

the details are that it is super damn expensive. last time i ordered some it was about $40 a foot.

 

Goopy Apex Seals...

a large thumbs up. i was doing some initial road tuning in July running on gas and a water meth AI combo. the AI was being delivered thru fuel injectors pre and post turbo.

or so i thought.

i was getting knock where i shouldn't. i was just running off the spring around 14 psi w my BW. it was really laying down the power. i was rolling into 3rd gear and the 295s in the rear could only hold 46% throttle. i couldn't figure out the knock until i figured the water in my water meth had plugged the AI injectors. i was getting zero AI.

note the knock spike in the rear rotor ... over 600 on my ViPEC.



i did swap out the system and eventually switched to E85 w a small nozzle delivered water meth component.

the bottom line is after numerous mid year knock events and more than 40 25+ psi dyno pulls including 5th gear my Goopy seals still show top tick compression!

i am using them in most of my builds going forward and would love to disassemble my motor to take a look at them but my motor doesn't want to come apart.

gates hose like $20 on amazon, think its about the same price at a napa store

 

My tank view, no E85 thru it YET





I really think the overspray came in from the port just above the fuel pump hole.

 

Here are the fuses I use for most of everything.

 

Howard, Take apart the pump and see if there is any gear wear. E85 has been known to break down certain filters/socks which gets sucked up by the pump( also, e85 has a higher chance of having containments than gasoline). Which in return draws more power and blows the fuse. That black stuff could possibly be from the wear of the gears in the pump or other parts of fuel system no compatible with e85. Judging by a quick look at your pictures it's worth a shot to see...just tying to help! Case

 

I bet you were relieved when you found that the motor still had compression. Any more ideas on why the engine would turnover will no compression pulses even though it still had plenty? I'm trying to wrap my head around how that can happen

 

here's the chart that tells the tale as to my fuse. i can't plead ignorance because i posted the chart in my thread "Fuel pumps 2013." note the required amps around 73 psi (43 rail plus 30 boost)...



16.4 amps at 12 V

18.3 amps at 13.5 V

running the pump as i was at 16 V would require 21.6 amps.

the above is calculated at 30 psi which is the top boost contemplated w my 4094r.

we didn't have enough time to get to 30 on the dyno so i was running a max of 26. further, my rail pressure was 39.

so 39 plus 26 = 65 PSI.

15.6 amps at 12 V

17.5 amps at 13.5 V

20.7 amps at 16 V

the fuse worked fine for a couple of months and over 40 dyno pulls including 3 runs thru 5 gears on the dyno. it also worked fine on my first Texas run thru 4 gears and a bit of fifth.

it was 3 hours between my first and second run so it certainly had time to cool. the fuse failed on the second run as i shifted into 4th.

i do feel the fuel filter blockage was a contributing factor but the fuse would have probably failed at some point at the 16 V level.

i will upgrade any wiring as well as the fuse and may see if the pump is adequate without the BAP.

it is worth noting that the OE fuel pump fuse in the FD is 20 Amps.

R!, thanks for the pics.... i do now believe the black deposit under the fuel filter is a result of overspray thru the small round hole near the fuel pump access.
