Another good option would be to retrofit a late model OEM module. Especially since you already have a new tank. Lots of benefits to this. Bucket style modules keep the pump submerged at all times for better cooling and you don't have to worry about fuel slosh. The bucket is kept full by a built-in venturi pump. Another plus is replacment parts availability, whether you need something in a hurry on a road trip, or long term. Who knows how long some of these aftermarket parts will be supported.
I used a module from a 2004 Flex fuel Tahoe. Carter brand, ~$50 from eBay. Seems to be the equivalent of a 255lph. Downside is you have to cut and weld on the tank. Not a big deal if you're decent with fabrication. You can retain your existing fuel level sender or modify the one on the module (have to remove and jumper one resistor, and add another in parallel) Last edited by adynes; 02-06-2019 at 05:24 PM. |

Thanks for the information, I will definitely keep it in mind as an option. Dale

Just wanted to update this thread. I did the EFI conversion and went with the Holley Muscle Car Module, https://www.holley.com/products/fuel...s/parts/12-302 and the install of the module was very simple. It made one of the worst parts of the upgrade the easiest. So far it is performing very well. I even ran the tank down to 1/4 and did some hard accelerations and there was no issues. Even at max throttle and high RPMs the unit has no problems giving the EFI what it needs. It is also designed to work with the Holley Sniper so they are a good match. I also highly recommend the Holley Sniper and Hyperspark distributor, great upgrade.

I wheel the hell out of it, and haven't experienced any fuel starvation, but I also dont run it down to E. I have had it down close to an 1/8th before, and it's been fine. That said, there are some cars where the tanks just can't help sucking up air if they have less than a 1/2 tank.

Buy the Tanks brand directly from them and then get the float less gas sending unit for your gauge

In my situation I had a brand new tank and system already installed and did not want to have to take it all out and spend the money replacing new items. I am just letting people know that this is a great option that works and really simplifies the entire process. Plus you don't have to run a return line. Now we will see how long it last. Hopefully I won't be back on here complaining the pump failed. If I had decided to do this back during the restoration, before installing my current system, I probably would have went with a tank and system designed for EFI with an in tank pump. That is another thing I like about the Muscle Car Module, it has an in tank pump and when you are driving you really can't hear it. You can hear it when it does the 5 second prime before you start the engine but once the engine is running you really can't hear it. Much better than an external pump.

Seems like the biggest thing I'm reading here is everyone is trying hard to get away from running a return line the entire length of the car. That's really not very hard to do.
I'm one that prefers a full length return, and have the return as close to the carb or FI unit as possible so I'm constantly getting a cool shot of fuel that doesn't have time to heat up during those long idle and low cruise situations. |
