EFI in tank fuel pump
Posted by: CH47CC ()
Date: January 06, 2020 09:39AM

I am in the process of installing a SC 3800 from a 2005 Monte Carlo SS, in a mid engine configuration, in a 68 Monza and was wondering if anyone has put an electric pump in a stock fuel tank. Thanks, Troy.

Saw this in-tank pump last week. Has been done before by others but don't have time to search further right now.

Troy, Do you have any pictures of this project?

Matt, Do you happen to know what PSI range the pump has?

The fuel pump is a GM EFI fuel pump, it dead heads at 90-95 psi, it is recommended to set the fuel pressure at 38-45 psi, and it can go up
to around 75psi (I think)... it has plenty of flow to support 300 hp.
One thing not mentioned is that in tank set-up also includes a new fuel
level sensor, and that also mounts in the top of the tank. I have run this
set-up since 2015, and have had zero problems with it- Ray really thought
this through, and made it a really slick, simple and easy way to do the
in tank EFI fuel pump conversion!

I installed the pump and a portion of an S-10 fuel tank in the top of my Corvair tank. It's been working like a champ for over 20 years now. The flange is sealed with JB-Weld and held in place with screws and nuts. The stock gauge remains in place and the stock fuel line is used for the return line.

If you want to keep the fairly stock look and don't like to cut metal, we use the original sending unit and attach a Bosch pump to the end. Max pressure is approx 100 psi, so plenty of room to do traditional EFI. Revolution electronics (a Corvair guy) supplies the connector. The special Teflon wire is available on eBay for a $1.00 per foot. You can put a little JB weld over the connector inside as insurance. Do not try to make a connector with JB Weld to the Teflon wire.... as it Teflon.




I like the American-Pi setup, so don't think I'm "downing" it at all. just thought I would throw out an alternative. We run the return into the fueling tube as room is a premium at the sending unit. Keep in mind, if done properly it's one of those things you never change. My latest fuel pump install has been in my Convert Convertable since 2013 (Bosch)

We offer it as a service to our kit owners/buyers but the disclaimer and hold harmless is a mile long. I also plan to make a DIY video soon, but the stinking job keeps getting in the way.

That's a slick in-tank solution!

I went with an external pump but it's a bit noisy where I mounted it.

I never found an external pump that was not (bearable) noisy, hence the internal pump.

How much fuel capacity do you lose with Ray's setup?

On a related note, if you need to add a return line into your existing tank, there is a kit to do just that from CPP. Check out:[www.ebay.com]

I used the CCP unit. Very easy to install.

The return line thing has haunted me for years and I always took the filler tube out and brazed in a 5/16" line. This worked great locally, but there are some that are not comfortable brazing, welding or even epoxy. This goes inside the wheel well and is removed if the filler tube has to be removed from the car.

I developed a quick and easy way to add a return to the Corvair and will be offered for use on our kits. you could easily build your own, but we will offer for those who just want to install and go. **I am using a pipe to emulate a filler tube

Thanks for looking,

Ted

I like the turn down on the hose nipple on your setup. I have one from Calvairs that is a 90 degree, puts a little stress on the return hose connection I'm uneasy with (can you imagine if you were driving and it broke...).
