Alright im wanting to up the fuel line size coming out of the fuel tanks to either 1/2 or 5/8 now with two tanks on my OBS is there a upgrade for the tank selector switch so that it can flow more fuel or should i just go to a one tank system wich leaves me with only 16 gallons of fuel??? any suggestions thanks

I clicked on the wrong forum this should really be in the upgrades and aftermarket my bad:shrug:

Robert, which fuel pump are you using? Have you checked fuel pressure at WOT?

 

[gregrob]

Moved it for ya

You could put a bronco tank in the rear and use it only. 33gals I think.

 

[kainers]

X tank in the rear 44 gallons I have one if you need it

 

[racehauler]

I have thought about deleting the selector valve and putting a cheap electric fuel pump on to pump the fuel from the rear tank into the front tank. You would also have to have a vent line running from one tank to the other so that you wouldn't pressurize the front tank.

That way you could eliminate air in the fuel like they do on the SD.

could find 4 electric valves and make your own selector. But I suspect it'd run $500

Joey im running a SD stock replacement pump, jacob has come up with a pretty good idea of plumbing another SD replacment pump in between the filters cause my filter heads have 2 inlets and 2 outlets that just leaves me with the supply from the tanks to the pump problem if i put a single big tank in the rear is that going to be a ton of extra weight in the back that will make it sag real bad with a load on? im in the process of getting a fuel pressure gauge put in so i can see just what its at at WOT.

I am in the process of doing this now. I have insatalled a bronco tank in the rear, 5/8 pickup, -10 to dahl 150, -10 to bosch 044 pump, -8 to y-block, -6 to rear of heads, -6 from front of heads to reg and -6 return to tank. I have a small diesel rated pump to trans fer from front tank to rear tank.

I believe you also loose the spare tire mount with the bronco tank.

Does the bronco tank fit in the same spot with no modding, Do you have to use the tank straps from the bronco and what year of bronco tanks work for it?

the bronco tank mod kinda sux. its foot print isn't as big as the stocker so it fits. use the stock skid plates/straps to hold it just use some all thread to drop them down. you loose the spare tire and your exhaust will hit it.

It doesn't fit that well.

OH and a stock SD pump will stand up to stage 1's in the right fuel config. testing on more setups is coming. But its a bigger pump than most give credit for. The problem is nobody puts a fuel pressure gauge in, so they never really know..

I have a s/d pump and I just put a gauge on it the other day I have 1's and a decent tune just not worth a shat for daily driveing. I launched with 5 psi boost and did not lose any fuel pressure even in od and locked converter it is rock steady 65 psi.. I think I will put another one on when I get oil and the sticks get opened up alittle just for insurance . I need to rethink the 10 micron racor filter tho. Might cause a problem later.

P.S. I have #6 line from the pump to a Y then to the heads .I come out the front with stock return lines into an aeromotive A1000 regulator then return thru the stock lines to the tanks.

well im on my way to having a fuel pressure gauge, im sure that it will keep up with stage 1s but im running hybrids 230ccs. The exhuast is not a big deal cause i have stacks in the truck so not an issue. and iv got the pumps part of the fuel system figured out so im just trying to decide about a tank, im leaning towards the bronco tank i think.

Go with the bronco tank and run two sd pumps in series.

 

[Deerezilla]

If you do that Bean don't you have to find a diferent spot for you spair tire?

 

[bean]

Ya but who cares, when was the last time you used the spare under the truck? I know I never have on any truck I dont think. Its just something that has to be done if he wants to go with bigger feed lines, trying to keep the dual tanks and the selector valve just isnt worth messing with just to keep the spare under the truck. IMO

 

[444smoker]

I agree i have never once pulled the spare out from under the truck and its a 265/75/16 and i have 35s on the truck a little clash there. i havent looked at it yet but what is all involved in modding from the stock tank pick up to a 1/2 or 5/8 pick up out of the tank should you keep it a steel line?

Robert

 

[Tom S]

Robert have you looked at the instructions for the intank stuff on ITP's site for a idea?

Tom

I plan on using steel tank pickup lines since I suspect copper would fatigue over time from vibration. Also going to call my local ASCO valve rep to find out if they have a 6 port 12 volt electric stainless valve that would work for the dual tank supply/return setup. This would also allow the use of an AirDog/FASS unit like some of the SD guys use.
