Aftermarket Fuel pump confusion

There seems to be a million options for replacing a stock lift pump. Now, what i need to know is which one can be installed easiest? I would rather not drop the tank if i can avoid it. I think this is required with the FASS. I am now looking at the walbro kit. I gave up on holley blue because I have heard of too many failures. Plus it is designed to be run with a carb. Money is not a real big deal on this issue. I just want a quality set up that is easy to install. i have little time to take a truck apart and roll around in fuel. Please help guide me to what system I need to meet this criteria. Thanks so much.


Plus any inks and pics would be appreciated. And estimated install time.

Vulcan Pusher Pump System, relocates stock LP to the frame rail. I'm currently working on a custom setup for my stock truck. I hate this new intake lift pump I got under warranty back earlier this year. I'm going to get a stock carter and mount it the frame rail in front of the take and use it to push from the intake pump, big lines all the way to the fuel filter, replace fuel filter housing with a spin on filter etc.

Both Vulcan and Glacier Diesel offer some really neat fuel system options for our trucks.

I do a new draw straw if possible, and go with a Walbro mounted near the tank.

Is it neccessary to hook anything to the fuel tank? I don't know what is involved in this. I thought hooking these things up was just tapping into the main fuel line on the frame rail. But, i have read some threads where they said they hooked something to the top of the fuel tank and dropping it made it easier. What was involved in hooking up your fass system, and which system do you have? Also, what came in your kit? Was it everything you needed to get rolling or did you have to buy extra trinkets someplace?

what is the purpose of the draw straw? Can a walbro be hooked up without messing with all that?

I still have read cases where the stock LP will fail after being relocated. Have you heard this? and is the stock LP provide enough fuel for future upgrades?

The draw straw gives you less restriction sucking fuel from the tank. The factory module is junk-- not just restrictive but prone to air leaks and other issues.

A walbro can be hooked up without it, you just need to use the factory plumbing and adapt it to the pump.

Yes, it can and often does fail even with being relocated.

The problem with the factory pump IMO isn't so much the location on the engine as it is the internal bypass. When the engine isn't drawing much fuel, the pump has to bypass a bunch of fuel internally, and this "dead head" pressure situation puts a lot of strain on the pump.

IMO, the best investment in fuel system reliability is a bypass regulator that relieves the stress on WHATEVER pump you are using and allows the fuel to return to the tank.

Ok yes you have to run a line to the fuel tank(dropping it would if id be easier, but dropping it is not a must). I didnt put the fuel line on there the guy that was helping me did that part. If i remeber right the oh the top of the tank there are lines coming from the top part and if you under the truck (drivers side) it is the furthest to right (or tailgate side). You will see more if you got under there. Also everything that we needed to do the installation was there except of course for the drill and drill bits.

Im not sure if you understand that or not im not to good on explaining over a computer. The FASS system is really simple to install and comes with pretty good instructions.

I know its a risk, I currently have a in tank lift pump so I'm just going to buy a new one and put on the frame rail. To do a FASS I would have to drop the tank, thats just something I don't want to do myself either.

Why do you have to drop the tank?
I know trucks are different but you have a long bed and so do I so i dont see why you have to drop the tank to do a FASS setup?

I have a short bed. Does this pose any unique problems with the install?

If you have a in tank lift pump you have no choice but to drop it to put a draw straw in it. Thats if you plan on running a FASS since you will eliminate that in tank lift pump.
