Competition Different fuel system for 12v?

[wildmanben]

How much hp will the stock lift pump setup provide for me sled pulling? I am almost at 600hp and wondering if the stock pump will give enough flow, or if I should add a Walbro System, or Haisleys or ????. Any suggestions on this?

 

[wildmanben]

Oh come on, no one pulls a 12v around here with more than 600hp?

I run the new big FASS system. An aeromotive a1000 is another option. I like the fass, simple install, and tied it in to my kill switch.

I would run opt to run an auxillarly fuel system and leave the OEM LP in place.

 

[wildmanben]

So when you say run an auxillary pump, are you saying add a pump between the tank and the LP to act as a pusher and then run a regulator instead of an overflow valve?

 

[zstroken]

Several systems just are paralleled with the stock system. I beleive that is how the Haisley system works.

12V's don't need that type of setup, it's actually useless!

Correct, that is the way the Haisley system works and it works well to a point then it needs more pump and more suction. I ran there system for years with no issues but slowly changed it over to what I now run, A1000 12AN suction, 10AN supply. Patty also hooked me up with a better filter housing using a big fleet guard filter (1000 series) but I still use there same inlet into the stock banjo bolt. If I ever send this pump in I'll get I. I. to knock out the inside/back inlet and put the stock system there and run a 8 or 10 AN inlet for the aux system but for now it's doing just fine... ... it's not that radical of a pump so in truth it really doesn't need it.



There system is hard to beat, especially for the money!

Jim and zstroken cleared this up already. By aux. I was referring to the how the Haisley system is setup.

 

[wildmanben]

Oh I gotcha. So Haisleys would be the way to go then?

 

[zstroken]

I like a setup that eliminates the stock system. Tie it in to your safety cutoff. These trucks are pushing 600HP and safety equipment needs to be thought of. I thought the Haisley system was around $500 and some change and still uses the stock lift pump. I mean if you have purchased lift pump in the recent years and know yours is good then it might be a good setup.

We run the big Aeromotive nickel-plated pump on the puller. JR Adkins put it together and installed it for me. Nice setup, no complaints.

Ben, build your own this way. Aeromotive A1000, 12an from bottom of fuel tank to A1000. Then 10an all the way to the injection pump. Dual feed 10an as well. I got some pics here: https://www.turbodieselregister.com/user_gallery/displayalbum.php?&userid=13880&albumid=18647. This was for my low pressure VE pump. For your application, just minus the regulator.

I haven't installed my big filter housing yet but it's the same one as yours, I still have the old housing on. I'll do it when I get back home.

[wildmanben]

Can you explain the dual feed you were talking about? Also, where do I go to get the Fleetguard Filter Housing? So do you eliminate the stock lift pump and filter housing then? Do you use the overflow valve and run that back to the tank as a return then? Sorry for all the questions, but trying to get this figured out. Looks like a good system thats relatively inexpensive also.

Thanks a bunch guys.

 

[zstroken]

I would remove the overflow valve and regulate that return line. Fulmer gave me some ideas on it.

 

[WShupe]

Ben a single -10AN feed and regulated return would work for you. If you were to double feed you would be better off to modify the throttle linkage and use the front side feed port.

Get the filter mount from Cummins, part number 142784S. Or a shop that deals with Fleetguard, Baldwin or Donaldson. They can cross reference that part number.

You can remove your stock lift pump and use a fuel pump block off plate from a big block chevy available from Jeg's, Summit.

This is a pulling truck right? What do you need an injection pump return line for?? :-laf

Inexpensive? Well compared to some fuel systems out there, maybe. The a1000 is about $300. Then depending on what fittings and fuel hose you want to use and locally availability will determine how much you'll have in it.

 

[wildmanben]

I suppose I would have to get a fuel pressure guage too. I figure that I would have $500-$600 into it. Will have to add up the parts again.

 

[Jim Fulmer]

I would have to get on my laptop to get the link but there is a p[lace in Florida that sells metric fittings along with metric banjos, washers ect to convert to AN style hose ends. Once you but the pump, fittings, lines ect it get expensive not to mention the PITA of dropping the tank ect. There are a couple of pumps you could use, the A1000 (600 lbs/hr) then from there they have an 800lbs/hr then up to a 1000lbs/hr.



I don't see needing a really big system but it's nice to have extra (cooling fuel) to return back to the tank. I still use the stock return, just tapped into the line and have had zero issues with it. You don't have to have the braided steel line but it is the best for rubbing purposes, I used the high pressure blue line. The inlets to the pump are M14 x 1. 5 pitch unless you remove the helicoil then it's M16 x 1. 5. the biggest M14 is an 8AN and you can modify the fittings opening to slightly bigger..... hence buy several. When I get to my laptop I'll post the PDF for the company BATT fittings in Sarasota Florida.

Jim, you mean here?? I saved the link from when you gave it to me.
