FS: Single Fuel Pump Conversions for LT5
 

Have fuel Pump problems? There is a solution! A conversion to a single high performance pump. Invested a LOT of time researching & building one for my ZR-1. Decided to see how much interest there would be in more of them. All stainless construction. High performance Racetronics Turbine Fuel Pump.
Specs & notes:
ZR1 ZR-1 LT5 New Fuel Sending Unit, Single Pump Conversion
? Entire unit made of Stainless steel, No more corrosion!
? All power leads upgraded to 16 gage for cooler running.
? All new High Performance, corrosion resistant Bulkhead.
? All New electrical Connectors upgraded; corrosion resistant.
? Simple plug-n-play installation, you just need to unplug one lead from the ECU, instructions provided.
? OEM single pump capacity = Nom 18.8 GPH @ 5 Amps.
? OEM Both Pumps Capacity = Nom 26.7 GPH @ 10 Amps.
? New Performance pump = max 67 GPH Capacity @ 12 Amps.
? System combines power leads from both OEM pumps to power the single Performance pump, no rewiring required, plug-n-play!
? New Racetronics high performance fuel pump installed.
? New pump is Turbine Type for long, sustained running at full power!
? Noise reducing sleeve installed on pump.
? Rated for up to 550HP at the crank.
? Fuel Supply tube modified for extra flow.
? Includes new tank flange seal/gasket.
I just added all stainless installation hardware to the kit.
These are not cheap to build and they take a couple hours to build. I decided that $400 shipped would be a fair asking price. Please PM me if you have any interest.

Re: FS Single fuel pump conversion for LT5
 

You should build a batch of them, it looks amazing, provides plenty of volume, should be bullet proof and is plug'n'play. What else do you want?
Great product!

happen. PM me information on how to pay.

Re: FS Single fuel pump conversion for LT5
 

Well after having trouble with the stock fuel system (two pumps) in my ZR-1
I was going own make my own based on marks write up. But Flyman 27
offered single pump setup for the ZR-1. Well that made It easier for me a
already made system that I could install with out to much trouble (getting
out the two pump system).Brought the single pump system and installed
It. Works great, but I noticed that the fuel pressure would drop as soon as
I turned off car. Not a big deal, turns out there is no drain back valve . OK
now my engine is a 368 cu.in. motor with 12 to 1 compression. Flyman 27
said just install a check valve from tank output to the engine.
And problem solved, holds pressure starts in about 3-4 seconds
and pressure holds for restart.
I'am very happy with this system and would recommend it if your having
issues with dual pump system.

Done. Sorry, it all came together this time [emoji23]

Re: FS Single fuel pump conversion for LT5
 

Got mine today. Thanks Dan for making, thanks Marc for bringing it [emoji3]

Looks awesome, can't wait to install it. Definitely great work!

Re: FS Single fuel pump conversion for LT5
 

I saw Matt's at BG, what a beautiful job. Looks factory.

Re: FS Single fuel pump conversion for LT5
 

Thank you for the kind words.

Re: FS Single fuel pump conversion for LT5
 

I am very interested as well. What is the one wire that has to be disconnected from the ECM? How do you suggest disconnected it? What does the computer know/do? Also how best to order your set up. BTW. I agree it looks like very nice work!

Re: FS Single fuel pump conversion for LT5
 

The pumps come with step-by-step instructions on how to unplug the ECM connector, it literally takes a minute, very easy.
You get your choice of a Racetronix turbine pump or a comparable Walbro gear pump. Same price.
The Racetronix turbine is pretty much dead quiet and is made in Canada.
The Walbro is a gear pump so it can be heard similar to the OEM pump, it is made in USA.
The pump is a very easy install.
You will want to order a new boot usually, they are stiff & tear easily if OEM.

I will PM you payment info.

Re: FS Single fuel pump conversion for LT5
 

do these need a one way valve installed in line, i read from here somewhere where he had to do that due to long crank to reprime fuel lines?

Re: FS Single fuel pump conversion for LT5
 

It's a matter of choice.
If you want a check valve for the Racetronix pumps, I can include it for free.
The Walbro pump has an internal check valve.
It's your choice.

I don?t understand that. My car with your Racetronix pump works perfectly and starts the same as before. If there was a delay I would not mind it at all since it would allow more oil priming which I do anyway (depress all the way down and hold while cranking) if not started recently. I remember you offered the check valve but I don?t need or want it. Thanks for an awesome product.

Installed the single pump from Flyman on my 1990, was about an hour job in total. What's really nice is that he's already done the wiring on the tank side so the sending unit plugs directly into the factory plug, no wiring needed on the tank side. The only thing needed is to remove the wire at the ECM, which takes a paperclip and a minute to push the pin out then cover with heat shrink. Happy I went ahead with the upgrade, an hour now will probably save me hours of frustration later when the originals decide to give out.

Re: FS Single fuel pump conversion for LT5
 

Received my pump a little over a week ago. The thing is a work of art. Looking forward to tackling install sometime next week.

Re: FS Single fuel pump conversion for LT5
 

These are still available. I stock ones with the Racetronix Turbine Pump (made in Canada) and the (Made in USA) Walbro gear pump. Your choice, same price, same performance specs.

Re: FS Single fuel pump conversion for LT5
 

Dan, have u ever measured if there was any difference in fuel pressure between the single v dual pump setup.

Re: FS Single fuel pump conversion for LT5
 

Short answer: No difference for me

I have a fuel PSI gauge in my Z and had been pretty familiar with my fuel PSI during various.. activities :) . Recently bought one of these through Dan's ebay (didn't realize he had them listed here). I had no issues with my dual pumps, but my sending unit tracings were damaged and my fuel level didn't read correctly. So my comparison is probably accurate for both systems functioning properly

Normal operation it sits around 45 PSI for me. WOT the PSI jumps up to around 52.

Previously I had an opportunity to talk to Haibeck about the single pump conversion and he said as long as it stays above 48 PSI at full throttle and 6000 rpm then it is working well. I have not experienced anything to make me disagree.

I have the racetronix version.

Re: FS Single fuel pump conversion for LT5
 

Any available? I'm a buyer asap.

Re: FS Single fuel pump conversion for LT5
 

Looking for two assembles. Still available?

Re: FS Single fuel pump conversion for LT5

Re: FS Single fuel pump conversion for LT5
 

I've tried cleaning unit my sending unit twice now, it works for a couple of tanks and is now again stuck at full. It's time for some new hardware, I'm going to the mountain run in May and would like to have this problem resolved. What do I need to send you?
