I may take you up on that if I am in the Granby area at some point. Thanks.I'm in Connecticut and did this swap awhile ago and then switched the transmission to a 5speed. You're welcome to take a look at it. There are some items I'd do differently if I were to do it again and/or may change at some point in the future
The later model plastic fuel modules are spring loaded and there’s a range of depths that it will self-adjust to. The hard part is making a proper mounting surface, it’s almost 4” in diameter. I thought about that with a poly tank but first all the tanks I looked at didn’t have a large enough smooth area to work with. Secondly I was concerned about sealing the opening with a flexible poly tank.
I ran this in my steel tank. It would be pretty easy to install in a poly tank.
I cut the hole in the tank and installed the assembly. I used their roll over valve as the vent and plugged the rest of my fuel tanks ports. Since yours is poly, I would use the stock roll over valves and vents. Either would be fine though.
On my Copper build I installed a 1999 Silverado 5.3 fuel module into a Trailquest steel 24 gallon tank. The module had plenty of adjustment depth.This is a good option but too shallow for the poly tank. I would lose 2.5 inches of fuel capacity since this goes down to 10.5 inches and the poly tank is about 13.
Holley makes a nice retrofit pump kit too.

This is the one I have, but not install yet either.I bought one for my V6 conversion slotted straight in to the 15 gallon steel tank, hasnt been used in anger yet and wont be for a good while yet.
So, if you go to the Photobucket link, go to Scrambler pics, and find June 24, 2009 you can see my fuel tank mod to make the pump fit. The seal is more of a sleeve and with careful building you can get a suitable flange built using a hole saw and common tools.And that is the pump I priced out on Rock Auto which looked perfect. I am going to give it a shot and make my own clamp bracket for the tank.
Ford had a recall where they put 2 one way valves in the fuel lines. It was to keep dual tank systems separate. I have one of those valves, but not the 2 required.I got the old motor out last night. I have a few people wanting it but two want me to ship it across the country which I was not planning to do if I can help it. The motor mounts from Dave's came in and I am waiting for the adapters for the tranny to the dana300. I am ordering the fuel lines, filter and gaskets this weekend. I want to run the fuel lines before I drop the motor back in plus do a bit of cleaning to the frame and engine bay. I decided to not do an in tank pump and run my E2000 that I had siting on the shelf that I forgot about. I am considering buying a second one and running it parallel to the other pump with a switch for redundancy. I doubt I will ever need it but it would be nice to just do a quick switch if needed. I would need to install check valves though in order to not back through the other pump. I am still figuring this all out to see if it is worth it or not.
I am doing the same swap and already have a CJ7 with an LS1. They are hard to beat. I had to wait months for my dana 300 to 4L60 kit to arrive. I plan to go with the Holley Terminator X MAX.
Yeah, those Ford ones are way overpriced for what they are. They came in a kit of two pieces. Somehow I ended up with just one as a leftover.Looks like check valves are pretty common to help keep pumps primed at startup.
As someone preparing to undertake this, please share.
We really need a general LS swap thread.
