In the 2000 silvy I got a fuel cell from db rods and fits nicely. Where are guys putting thier inline pump? My pumps the eliminator a1000, so it's not the smallest pump.. I still have leafs and don't have room to mount it right there next to the cell.. I'd like it as close and low as possible. I had it mounted on the frame in front of the axle but seems to have issues picking up fuel...granted the line from tank is prolly 6 feet long...not ideal.... Thoughts, ideas, pics? Thanks!
any setup ive played with that had a cell and external pump, the pump was always right next to tank and lower then the drain fitting. im aware on a truck this is hard to make possible
Shawn are you friends with Ryan on fb? The Ryan with the black and orange obs that runs 9s? He made a bracket for his... like a crossmember.
heres mine and it works well without issues

If you could mount it behind the tank hanging down it would be ideal. Get it as close to the bottom of the tank as possible. Definitely sounds like its a little high.
I have leafs running along the outside of the frame though David.. It's hard to have it lower than cell cause of how low the cell and truck set..

Can you mount the pump off one of the fuel cell mounts. Maybe make a plate that can bolt to one of the mounting tabs on the cell. Almost right where the hose clamp is at in your pic? I thought you had a Magnafuel pump? They usually will bolt right up with the supplied bracket.
Pretty much in this position.

When we where talking about it I did. Hooked it up and it didn't work right outa the box. So sent it back and said the hell with that. Lol That pic has the pump a little bit higher than the bottom of the tank, would that be ok? I'm pretty sure that's my tank/pics you had sent me when we where talking about it. Ha
I thought those were yours but couldn't remember. Yeah that pump placement is fine. Even a inch or two higher would still be ok. Just be sure to keep at least a 1/4 tank when doing wot pulls to be safe.
That gives me some ideas. Thanks Jon
Engine. Driven.
Looked. Couldn't find a kit.....would have been my first choice
Yup, I love my belt driven pump.Quote:

I have mine mounted in that area along with other high hp trucks and we have zero fueling issues.
My fuel pressure doesn't move a mark and there's always fuel there with the key off.
See that's where it's at now. But half tank and it won't pick up fuel hardly at all... The line goes up over the frames c notch so I was thinking that rise is about a foot higher than tank and pump. Maybe that's my issue
I've installed many pumps mounted in that area and never had an issue.
Just for example, my two lines come out of the cell, along the bottom, 90deg up along the front of the cell, over the axle along the frame, into one filter, pump, filter, which are mounted on the side of the frame.
The a1000 ran fine like that, and now the pro series does fine.
When launching, since the sump is in the rear and so is all the fuel, and you have 1/4 tank, there's no reason the pump won't suck fuel.
Just going over the basics, did you check the filters? Is the pump strong enough or is it getting weak?
Gotta enough wire going to the pump? Terminal/connections?
Filters clean and pumps brand new....literally no miles on it yet. Just me messing with it is making all this happen. Wiring is a massive ractronix kit for the pump only. Soldered connections and pulling power straight off alt....now idk if it makes a diff but mines not that far up forward. It's about where the front leaf spring hanger is. Further up the frame would be lower overall than mine is right now by prolly 10inches.

I'm pretty surethe '93 we just did is in that location as well.
When you say just messing with it, do you mean that you're not at the truck's potential and you're noticing fueling issues?
Do you hear the pumps whine/pitch change when you think it's not pulling fuel?
when my tank is low and i brake and stop, i hear the pump pitch get lower and i can tell it's sucking air.
I'd like to see the pump a little lower than that. Maybe 3-4" lower.Quote:

The line is so high right there that it would create a air pocket and then the pump would loose its prime when sitting for a while. While it was running it was fine. So I ended up running the fuel line under the axle and it took care of that issue. Most of the inline pumps aren't meant to suck fuel out of the tank, they need to have a good gravity feed.
Heres what my fuel system consist of and locations. Sorry if its a little dirty, street truck. I ended up adding a inline small pump that is wired to the starter solenoid. The Belt driven pump would take 5-6 seconds cranking to start at times due to cranking RPM speed. I would only build 10psi and wasn't enough to fire the motor. So I have the small inline pump that only comes on when the key is in the start position and it fires right up.

No not at potential at all lol. I think the notch is a lot of my problem to. The line goes up actually higher than the cell at that point. I think that could be the issues with my long feed line. May swap sides of the truck since the sumps on the other side to shorten lines and run mine like yours John. Creative. Ill try and build a plate and lower the pump down too... Or scoot it forward on the frame? But that would be a long line from pump to cell...but would be downhill
The notch is probably the issue with the line up high. I personally like to have electric pumps as close to the tank as possible. If you can get the high spots out pre pump with a lowered pump you will be golden.Quote:

So as a test I rerouted the the line between pump and cell. Ran it like Jon's and under the axle. The pump is 3x quieter and seems much happier. I'm gonna build a plate and lower the pump down. She's a low truck devon lol. Jon what's that belt drive setup run? Will it work on a stock crank pulley?
Good to see that took care of the issue. The belt drive gets a little pricey. It wont work with a stock crank pulley. You have to be able to mount a mandrel.Quote:

The pumps start at 550.00, then a high flow regulator to mach it probably 200.00 and a crank mandrel is 200.00 with belts and pulleys. Then it needs huge fuel line for feed -12 or bigger. It adds up fast
