Fuel tank/pump
Guys need some help.
Here is the tank I have. The motor is a LS3 465 hp. Should I use a external pump? If so which one. I have something similar now on a 383 with aftermarket injection with no return line and no issues Or internal....I don't know anything about internal is there a kit that I cut the tank and mount? Not sure how the pump stands up in the tank. What about flow rate?  Thanks in advance |

Re: Fuel tank/pump
Yes you will have to cut the tank if you want a internal pump. Does this tank have the baffels? If not you may want to stick to the inline pump. You don't want to starve the internal pump for gas when low on fuel.

Re: Fuel tank/pump
The other internal option is this one: http://www.summitracing.com/search/b...s?autoview=SKU .
Its more money but its a known name brand that can support almost anything you can throw at it.

Re: Fuel tank/pump
There is an OEM option. When GM started using plastic tanks, they went with a fuel pump module so they wouldn't need baffles. Basically the pump sits in a cup that is held on the bottom by springs. They come in different heights depending on the depth of the tank. For example, I found one from an 02 Silverado. The module is 15" tall, but it compresses down to 12". And there are others that are shorter. You can find new modules on ebay for less than $100, or look in your local wrecking yards.
