Using SD elec fuel pump as pre- booster for stock lift pump.
Wondered if anyone had thought of this, or has done it. The only reason I'm considering it, is keeping the stock fuel housing with the fuel reg etc. I ran a new set of hoses to the banjo fitting on the lift pump by cutting off the copper lines and threading it so I have good fuel supply to the heads from the pump. I was thinking that just sticking the elec. pump inline from the tank would help the lift pump and allow it to keep up better and/or alleviate problems with air in the fuel. Hopefully this would help with mileage and quiet things down a bit.
Feel free to poke holes in my theories.

I'm not sure I understand, you tapped the copper lines to add the SD pump inline?

No, I cut off the copper lines right at the banjo fitting and tapped them for aero-something fuel lines I bought in Denver when I put my new motor together. The copper lines and crappy fittings to the back of the head are completely gone.

or you want to run the sd pump inline along the frame?

Yea, that is what I was thinking.

The fuel bowl cannot handle the high pressure from the pump if you mean inline from the tank.

That was one of my concerns. I wonder if it could be tied in at another point. Of course that assumes the stock regulator in the fuel bowl will handle the SD pump pressure.

Re: Using SD elec fuel pump as pre- booster for stock lift pump.
I take it you want to use it as a kicker pump ? Go for it the stock lift pump could use alittle help.Mine is dieing I am running out of fuel in o/d.

Yea, I'm just being cheap and trying to avoid the cost of completely replacing the fuel system, but hopefully making a big enough difference to warrant the pump cost.

You cant do it that way, the OBS fuel bowl will not handle the pressure from a SD pump.
The stock lift pumps are a 2 stage pump. The 1st (diaphragm} stage draws fuel from the tank and sends it thru the filter bowl then it goes back to the 2nd stage (piston) where the pressure is bumped up to at least 45psi before it goes to the fuel rails
Re: Using SD elec fuel pump as pre- booster for stock lift pump.
it won't work. the lift pump is low pressure from the tank thru the filte rhousing then back to the pump where it then goes to high pressure in the second stage of the mechanical pump. if you put high pressure to the low side by adding the superduty pump you will destroy your stock pump in short order. the filter housing is deisgned for low pressure. it unlikely it will hold the high pressure. best be would be to just do a whole fuel system with electric pump with a primary (before pump rock catcher)and a secondary fuel filter after the pump to 2 microns. then plumbed into the head then out to an adjustable regulator then back to the tank with a return.

Re: Using SD elec fuel pump as pre- booster for stock lift pump.
I know a complete fuel system would be better, I'm just seeking a way around the cost of a regulator and filter setups. The pump is cheap enough.
So if loading up the pump is bad, what about after?
Somewhere the fuel goes to the regulator in the fuel bowl, will the stock regulator take the pressure?

Re: Using SD elec fuel pump as pre- booster for stock lift pump.
Geuss what I want to do will wait a few more weeks ,I am driving my "other" car, truck is needing some attention can't do that and drive it to work plus I do not want to go home after eight hours and work on more diesel stuff anyway.

One other option you could explore is a SD style bowl and HP oil reservoir with a with a regulated return.

I think I talked with someone about that once, maybe Bean. I think he was even going to sell me one at one time. Seems there were some wiring issues to the sensors on it etc, cant recall. It would still require a regulator, and that is the expensive part I am trying to avoid buying. If I have to buy that, then I might as well just do the whole thing. If I can keep the stock parts, and shoehorn another pump inline, I would rather do that. If not, I'll just buy pices at a time till I have everything.
What would be the problem with running it after the lift pump? I could tap the pump banjo for a single line to the sd pump, then T off that to the heads with my existing aeroquip lines.
I am rebuilding my filter housing with a new heater and seals next week so I'm going to look into this then and see how the return line is routed into the stock regulator.
No one has said anything about the stock regulator and whether or not it can take the pressure from the SD pump. Any clue?

Re: Using SD elec fuel pump as pre- booster for stock lift pump.
Timc63 has a nice write up on his SD pump based setup that you might want to look at. I also have some pics in my signature that you can look at. A remote filter system can be done on a budget. The top expense is the pump and the regulator. I know of some ways to save over the way I did mine.

Yes I believe it can. I remember reading a post on here where someone had put together a regulated return fuel system with a SD fuel pump, remote mounted filters and the regulator from his OBS fuel bowl. I wish I saved the post but I didn't. I dont even remember who it was and have searched for it a few times with no luck.
Re: Using SD elec fuel pump as pre- booster for stock lift pump.
Tom, I just checked out your pics. Looks like you've ben playing sonce the last time I saw you. Nice work. What differences did you notice? Did you get your fuel line from that place I used?

Re: Using SD elec fuel pump as pre- booster for stock lift pump.
from what I understand you did was completely bypass teh fuel pump with teh SD unit, fuel in the rear of the head then out to teh stock reg from the front of the head, if so then yes it will work but you bypassed the filter as well so its raw unfiltered fuel, if you get any water in it you jsut toasted your injectors and maybe teh motor too. you need filters and water seps!
