Fuel Pump Install Issues

[eamici]

Purchased the recommended Fuel Pump (255 lph Walbro & Harness) for in-tank installation.

The problem I'm having is getting the unit to fit into the tank and seated properly. Two things seem to be impeding the process. 1) the filter on the intake is positioned at a 90 degree angle from the pump/harness and 2) there is a metal divider inside the fuel tank.

The in-tank divider is hitting the filter in a way that prevents the whole unit to sit cleanly.

Any thoughts would be appreciated.

When I did mine I had a two prefilters one that had a centered hole (where it attaches to the pump) and another pre filter where that hole is offset. I used the offset filter. It made the difference between sitting properly in the sump and interfering with the sump. You may just need an offset prefilter?

My pump is a Aeromotive, but I can't imagine them being that much different. There are pictures in my build thread towards the end. Post #316.

You'll have to rotate the assembly to the right position to get it to sit over the divider and flush on the tank. Almost like putting it in backwards and rotating. Hard to explain but it will fit. And as Yama Bro mentioned, the offset filter works best and you have to install it as it would sit once seated. Again, almost a backwards fit until rotated.

Also if you require 255lph then you should be running a high flow fuel pump return

Checked out your pic. Your fuel pump is different than mine. The intake is not centered so it doesn't fit through the harness hole at the bottom. Checkout my pics9877798778

By the way...call me stupid but is it OK for electrical wires to be submerged in gas?????

As others have mentioned, the typical filter we use attaches differently than what you have. Must be oriented properly, but fits into the pickup sump area in the tank. And yes it's OK for those leads to be in gas. But is that electrical tape you have wrapped around the connections? You should be using connectors with sleeving that's specifically made to handle that environment. Like the Molex Perma-Seal™ Heat Shrink & Crimp Step-Down Butt Connectors pictured here from my Coupe build. Got them at DelCity.net.

Hey Edward. Its not electrical tape but a black heat shrink tubing. Yours looks much more sturdy. I guess I should to redo this?????

If you're talking about the typical polyolefin heat shrink tubing (most common) it's not gasoline resistant. Especially when submerged. There may be other products out there, but my research found the Molex Perma-Seal product. The sleeving is rated by Molex as resistant to a number of chemicals including gasoline. Pretty tough stuff. Plus has an adhesive that seals and strengthens the joint.

Take a look here (https://thefactoryfiveforum.com/showthread.php?27544-The-40-Watt-Garage-9365&p=339851&viewfull=1#post339851)

My fuel system was part of the engine package from Forte's, but regardless of supplier they have to fit into the same tank. Look into the fuel filler hole on the end of the tank with a flashlight and dangle the pump assembly through its hole. You'll see how the filter sock needs to be oriented (only one way) so it'll fit into the sump.

Concerning the electrical connections...I used the same crimp on butt connectors that Edward B mentioned. After ordering them, I talked with a tech guy from Aeromotive. He suggested using these connectors sold on Amazon. Here (https://www.amazon.com/Sopoby-Connectors-Electrical-Waterproof-Automotive/dp/B01DPS8DPM/ref=pd_sbs_328_2/134-1239330-2827460?_encoding=UTF8&pd_rd_i=B01DPS8DPM&pd_rd_r=cf43192e-e76e-11e8-a7f6-2b84c669aa9c&pd_rd_w=mhlh2&pd_rd_wg=Btpa7&pf_rd_i=desktop-dp-sims&pf_rd_m=ATVPDKIKX0DER&pf_rd_p=7d5d9c3c-5e01-44ac-97fd-261afd40b865&pf_rd_r=J9TTWKX3JRFQC9BMFECK&pf_rd_s=desktop-dp-sims&pf_rd_t=40701&psc=1&refRID=J9TTWKX3JRFQC9BMFECK). He said he personally uses them for fuel pumps. I can't verify they work or will hold up, but it's another option for anyone to consider. It's also a lot cheaper then the Delcity option; I had to order a minimum of 10 and the shipping was expensive. It cost me about $32 for the 10 connectors. The connectors from Amazon are $14 and you get 50 connectors of different sizes.
