P-Pump shutoff for racing?

[zstroken]

I ran an ED shut off was a nice piece, had to do some work to mount the solenoid. It was just a solenoid from granger. I got the idea after I saw gwoody setup. It does take 12v to the solenoid to retract the pin, then the solenoid would pull the pin. I had it tied into my keys witch and the rear of the sled. Either of them would activate it. I also had a toggle switch to bypass it. So the pin wouldn't pull when I wasn't hooked to the sled. It was a pretty slick setup, and had zero issues in the 4 years or so I had it. I also would close the butterfly during transport. Figured it was a good way to ensure the system worked

I am sorry I miss worded my question. Why is there 2 regulator ports? I plan suction from tank. Outlet from pump and one regulator on the pump. The one pictures has 2 regulator port fittings and inlet and outlet.

i have a drawing at home il show u when i get back from super bowl party. in words i have in and out on waterman. the smaller port goes straight back to my tank as a return.on the dump valve the feed and the out to the injection pump. the smaller port also goes straight back to the tank. i have 3 seperate return lines to the tank. the waterman return, the valve return and the unused injector fuel return. seperate cause they all have significant flow through them . and necking.them down into one might.get to much pressure and back up the injector returns. everything has its own seperate check valves as well.this is my setup anyaways and works great

[coldsmoke]

sorry 4 returns the injection pump return is also seprate with no overflow valve

Sweet. Might just have to get one then. Notice a significant increase in power without a filter?

i dynoed both it was 12 hp difference in my setup . so not leaps and bounds but every little bit helps at the track

Any pictures of your setup? And do you mind me asking how much it was? Saw the picture on ED but wanting to see it close up.

Gotcha.

Can't find the dump valve or shutoff on Haisley's website?

[coldsmoke]

Don't think I can justify a trip to Indiana for a few hundred bucks. Haha. Thank you!

97rada this is the setup i use and works for me in my application

That's exactly what I wanted. What size are your returns from the injection pump and the 3way dump. I Wanted to do one -10 or-8 return to fuel cell that contains my injection pump return, injectors return, waterman regulated return and the 3 way dump valve. See anything wrong with that? Just don't want 10 lines running to the back $$

After reading your post I think I will run a few returns and call it a day. Do you have a check valve on the injector returns? I am thinking one from the waterman to tank. One from injection pump to tank. and then combine the 3way and injector (with check valve) since I won't use the 3way all the time.
You don't need to use the 3 way to kill the engine do you?

[coldsmoke]

no i do not have a checkvalve on the injector returns .and no i use the regular arm to shut the truck off. if u use the 3 way valve it takes a couple seconds to burn up the rest of the fuel and then u lost prime for the next start! only use it for emergencys or when i change my filter .

[coldsmoke]

my 3 way valve return and injector return r combined exactly like the picture with no check valve

Sounds good. That's exactly what I wanted to know. Much appreciated.

This helps me out quite a bit as well, thank you! What are you running for a filter and where did you get the fuel block? I'm gonna be sucking out of the stock tank with a sump due to rules not allowing fuel cell. Hopefully it isn't a issue.

My 3 way dump consisted of a $40 divertor ball valve from Grainger. One direction supplied the pump, rotate 90 degrees of the handle and it returned to tank. I even just used the Ebrake cable to activate it. So if I wanted to dump it, I just pushed the Ebrake pedal and it rotated the valve.

I think it was around $500 that has been probably 7 years ago. The black cylindrical item is the solenoid. The red thing in the background is unrelated.

u can barley see it in the top of the pic. i just use a cummins universal filter mount and cummins/fleetgurad filter. dont have part numbers but cheap from cummins
