Installing an aftermarket fuel pump.
Well just got my Mcleod twin disk installed, next up is the fuel pump install before I start the twin turbo build. I have one of the Walbro 400LPH pumps that i'm installing. I'm on the fence between cutting the bucket open at the bottom and running the sock out there or building a stainless steel hangar to hold the pump.
I'm looking for pictures of how people have modified the stock bucket to run aftermarket pumps since it won't work with the way the bucket functions.
If you have pics of how you modified the bucket for the fuel pickup please post them. Also if you built your own pump hanger instead I would like to see pics as well.
Thanks
Jim
P.S.This is an 01 so it has the bucket that's on its side.

I've talked to Jon about it before, he's the one that enlightened me to problem. I'm just hoping someone has a decent picture of how they ran theirs. I'm starting to think fabbing up a custom hanger might be the best thing to do. My biggest concern is fuel starvation under heavy cornering and I think the stock bucket system is designed to handle that best.

The pump siphons from the tank to the bucket and the pump then draws the fuel from inside the bucket and sends it up the fuel lines. It's supposed to keep the pump submerged to prevent fuel starvation during hard or lateral acceleration. Unfortunately there is no aftermarket alternative bigger than the GRJ420 pump which is only 255LPH.

Hey Jim, i'm wishing now that I would have snapped a few pics before putting it back in the tank.
You're going to lose the use of the bucket in either case, so if it makes it easier for you to mount the pump in the bucket with the bottom cut out then by all means. Otherwise weld a stainless bar to the bottom of the hat and mount the pump on that. Just double check your filter height and location when installed either way to make sure it's not sitting flat on the bottom which would choke it off, or too elevated that you would lose effective capacity.
Upgrade your wiring while you're in there to the heavier gauge from Racetronix.
As long as you keep the siphon effective, and don't bridge the tanks, then the drivers side tank is always going to be full until you get under 1/2 tank. I would say even in hard cornering, there's no way you're going to starve unless you're under 1/4 tank (drivers tank with pickup still 1/2 full). So if you're going to do some spirited turns, just stay over 1/4 tank and don't worry about it.

I appreciate it as always Jon. I try to keep the car above half unless I'm going to the track so then I should be good. I just don't want to dive into the pump install and realise I needed something and have to find a way to work....DD problems...Anyhow i'll quit being a little girl and just get it done. I'll take a few pics for and post them up. Seems it's pretty rare.

I prefer that style of hose as well. I have to check to see what I have on hand right now. I know I have a few different socks, hoses and clamps.
Anyone know what type of plastic the bucket is made of that's fuel resistant?

Finally got around to installing the Walbro 400 LPH pump. Once I got everything disassembled I cut the old canister pickup and check valve off the bottom. I inserted the pump and used the 45 degree sock from Deutscheworks. I put the top piece back on the pump forcing it down till the pump was snug( about a quarter inch further than stock). After that I used some fuel resistant glue to make sure it held. I put it all back together, and it runs just like the stock pump. When I get home I'll edit this post and break down the text and pictures, doesn't work well on the phone.

ahhh I see now. You broke the tabs off the sending unit is that what the zip ties where for? How did you get the lid/hat off? I have taken mine out 2 or 3 times and each time is a beast to pop it off that lip inside.

yeah, caught the lever arm while removing the bucket. I have a t-handled hook that i use on one side, while i use a screwdriver to push down on the opposite side. Takes about 10 seconds.
