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.

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.

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.
