Upgraded the zl1 pump in bucket

[Tarendor]

In the past I upgraded to the ZL1 pump. When I went to E85 I quickly ran out of pump. I decided to add a bap and outran that too. So then I added an auxiliary pump. At this point I decided that I wanted better than the ZL1 pump, but didn't want to lose any functionality of the oem system and I didn't want to spend a bunch of money on some of the name brand systems.

So...

I decided to swap out the pump in the bucket and keep all of the oem systems in working order while converting to a return style system.

With my new in tank pump I still have saddle side pick up and the fpcm still reads total fuel pressure. The pump is 340lph compaired to the ZL1 @ 250lph and is pwm.

Picture 1 shows how I added x3 umbrella valves to go with the oem black one on the bottom of the bucket. You can also see that the venturi is connected and the return flow pipe has been modified a little.

Picture 2 shows how I removed the oem filter from the base but left all of the legs. 1 leg hold part of the sock and 2 others are in place for the spring rods.

Picture 3 shows how I shaved all of the stuff on the top of the black core except for the 1 hose hook. It also shows how I opened up clearance holes for the return line and to allow the feed line to relax into when the housing is compressed during installation.

Picture 4 shows all of the lines and electrical in the relaxed position.

Picture 5 shows the new feed fitting. The old feed fitting is now the return that flows back into the bucket.

Picture 6 shows the complete unit ready for installation. (At the correct 6.5" compressed height)
The oem pressure regulator is in place only to block the hole and serves no other function. (1:1 rising regulator does the job now)

Picture 7 shows the complete plumbing of the fuel system

From your signature you don't seem to have spared any expense. So my question becomes why don't you check DSX Tuning for all your E85 parts?

I am not taking anything away from companies that provide kits and/or ready made solutions. I just feel that with some skill, know how and some tools a lot of stuff can be done at home.

I am a little old school and like to do all of the work myself that i can. I love to tinker and figure out how to do stuff in my garage.

I also built almost every part of my signature myself.
Of coarse I bought parts but did not buy any kits.

It's time vs money

It took time for me to research and figure out how to do a lot of the stuff that I have done vs just paying to have it built or done.

I enjoy the process an am willing to share how I do things.

I found no guides or references to do this bucket this way so I figured it out myself and made this post.

This project was very cost effective for the gains in flow and I could do this setup for a returnless style too.

I am making one for a local buddy that wants to go E85, so I am also setting him up with the way I did all of mine.

To me this is what this community is for, share and learn.

Very cool work!

That's a really great way to see things!! I/we appreciate everything you share with us folks on the forum. I too love to share all my "knowledge" on what I have done/learned over the past 11 years working on my Camaro! It's how we educate and share for those who want to know. Well done/said sir!!

[racesloth]

Very well done!!!

Not questioning your abilities mate, when I don't know the answer I have to ask a question. Nice work

Why not run a Y after the filter and feed each rail in parallel? That way you can put the crossover on the outlet and tie both FPR ports together?

The main reason I didn't do it that way is that I didn't like the way it looked under the hood. LoL

The way I have it set up should give all cylinders equal pressure with the regulator holding pressure at the end of the system.

At some horsepower level I always ended up modifying kits anyway, particularly with nitrous. Kits can be good when you are in uncharted territory, but everything made for mass production has compromises and frequently can be improved upon.

Thanks for the writeup. I may end up doing this.

A lot of interesting things are borne out of necessity.

I like it when I explain these things to my wife and ask her.."does that make sense?" And she replies with "does it make sense to you?" Wich of coarse I reply "yup" as she goes back to her game that I interrupted. (Good times)

The way Joshnmn suggested is optimal.

You claim you kept all the OEM features...
You haven't kept the ability to control fuel pressure VIA FSCM, and you will likely max this out also. I don't see the problem on spending money in this area. The dual/triple options on the market give you steady, repeatable fuel pressure that makes tuning easy. You can run a stock FP sensor on any system and some aftermarket options do have the saddle pickup.

I think its a bit complicated. You could sell all of those parts and buy an AGP dual pump kit for $1500. You already have everything else you need. It's not a terribly huge investment for a safe fuel system.

Have you tried tuning it yet?

Sorry if I sound negative, but you're reinventing the wheel.

[Tarendor]

I like to build stuff. (Of coarse I am re-inventing the wheel) imagine if no one tried to take a different path vs the beaten 1.

To me it's not complicated at all, I like to tinker.

It's a pwm pump that is controlled by the fpcm just like the factory pump was.

My "whole" system was fun to figure out and was cheaper out of pocket then buying a ready made kit.

If I outrun this setup I will change it.

Tuning it is no different than Tuning your stock system because the pump is pwm just like the oem, and the fuel pressure is read from the total source that includes all of the pressure/flow sources just like the oem. (This is the easy part)

I could have did it without having it set up as a return system if I wanted too. But since I also have an aux pump (not a kit) I went return style to eliminate the psi spike when the aux pump kicks in. (That's part of that pesky Tuning part you were worried about)

I am not going to go down the rabbit hole with you. If you like it cool, if you don't like it that's cool too.

I am just sharing what I built.

You mad bro? (Makes me think I shouldn't try to share my silly projects... sheesh)

I'm not mad at all. What I would really love to see, is someone use the ZL1 basket, add 2/3 higher flowing pumps, re use the drivers side pickup, re use the FSCM control, (adding dedicated power circuits for each pump), to actually retain OEM control and supply enough fuel for over 1000whp on Ethanol. Being able to tune the FSCM file in HPtuners to control FP without the use of a mechanical FPR would be killer.

Your post made a couple false claims, and I was just having a discussion about those claims so future readers don't believe them.

Maybe you're mad.
