87 Fuel Sender Conversion
Since photosuckit has made a change that does not allow 3rd party hosting without paying $400 a year, I decided to redo this how to on what I did to a stock 1987 sender to use with a LS swap. This sender is for the Driver Side Tank,
Pictured are the parts for the conversion of a 1987 GM Truck fuel sender for use with an LSx engine. Sender: Spectra Premium, Driver side tank: #FG05M (pictured) -OR- Passenger side tank: #FG05N Fuel Pump: Bosch #69225 (same as an ACDelco EP381) Kit includes clamps, fuel line, isolator, wiring pigtail and clamps for install. Strainer: Spectra Premium #STR01 (required for Fuel Pump Warranty) Fittings: Jegs 3/8” tube to -6 Male AN Fitting (#100551) Feed Line Earl’s 3/8” tube to -6 Male AN Fitting (#165006) Feed Line Earl’s 5/16” tube to -6 Male AN Fitting (#165056) Return Line (I used one Earl’s and one Jegs because of cost, I saved a few bucks & Jegs did not have the 5/16” fitting)

Re: 87 Fuel Sender Conversion
First step is to cut off the bulge on the ends of the supply and return lines coming out the top of the center. First picture, the left line is the 5/16” diameter return line, center line is the 1/4” diameter vent tube, and the right line is the 3/8” diameter supply line.
Second picture is after I cut off the bulge on the ends. Once the ends are cut off, de-bur the ends and the ID of each line and flush the lines with brake cleaner to remove all the metal shavings.

Re: 87 Fuel Sender Conversion
Next, install the adapter fittings on the corresponding line. Shown here is the 3/8” Feed Line fitting. Tighten as per the manufacturer’s directions.

Re: 87 Fuel Sender Conversion
Repeat above step for the 5/16” Return Line. For this line I had to move the support tab for the line on the sender out of the way and bend back into place once the fitting was installed. I also had to resize the line using a pair of regular pliers, being careful to keep the line round.

Re: 87 Fuel Sender Conversion
Next install the Fuel Pump to the supply line on the sender and install the strainer to the bottom of the pump. The clamps shown on the black like are the special fuel injection clamps that hold better then standard hose clamps.

Re: 87 Fuel Sender Conversion
You now should have a complete ready to install sender to work with your LS Swapped Square Body!
I used push lock hose and fittings with -6 ends to connect the sender up to the rails on the engine. Quick and effective. For the metal lines on the fuel rail on the intake, I used the same Earl's fitting without cutting off any of the factory line. Sorry, I don't have a picture of that set up... My son has also done this same conversion using a Walbro 400/450 pump. the only thing he had to do different is the bracket on the bottom of the hanger needs to be cut off and a hose clamp used to hold the pump to the tube next to the pump. That set up supported his 550RWHP on his turbo'd 5.3 ![]()

Re: 87 Fuel Sender Conversion
It's not necessary to have an -AN fitting on the fuel sender. Don't want to confuse other people out there... I've ran 8 years on a regular hose clamp on FI hose to the stock 87 filter.

Re: 87 Fuel Sender Conversion
I'm glad you cleared that up 87chevy.com. I have used FI clamps before on temporary basis. I personally prefer braided lines. I use braided lines for power steering hose, fuel line hose, transmission line hose, catch can hose, and steam line hose. I wish you all the best for your swaps. Clark.

Power steering is different.. 750psi vs fuel 70psi. it requires special hose and matching fittings. I have used aeroquip blur nylon power steering hose and fittings without a problem. I wouldn't recommend a hose clamp on a pressure line unless I was stranded. Clint

To Clint's point, it is not necessary for the AN fittings if you want to use the fuel injection rubber hose and the clamps, they will work.

Re: 87 Fuel Sender Conversion
I did the same thing with steel AN fittings, I just ran a drill through the center to make the ID same as the sender pipe and then silver soldered them together and then used tefelon lined steel braded hoses
