I am well aware of the wear on the pump issue...and truely expect to be replacing the pump sooner than later


I wouldn't recommend running without some type of sock in place

I'm looking for a good compromise for a sock...so far I don't like the options. I think I may just put a screened pickup in there??

if so, that's allot of work

Swoope, what octane are you using? 91?

Premix + gas = works fine . Just ask the millions of 2 stroke premixers around the world . Sure they recommend you shake it up before use but that is just for even distribution .

Idemitsu + gas = works fine . Been there done that- used a case

Fp+ + gas = OK probably - that is what it was designed to do right ?

Fp+ + premix + gas = ??????????????????????????


Ten points for guessing which one has the most question marks hanging over it

How's Fraken Pump running? Got a few concerns with what you have done.

Couple of questions / comments:
1) What was the reasoning to cutting the hole in the reservoir?

to catch the slosh heading to the center of the tank in left hand turns!!!!
2) How are your low fuel start ups?

maybe two cranks longer, yes it is noticible
3) Have you had any starvation issues? (more than normal anyways)

just finishing my first tank. long drive to atlanta tomorrow! more info then..

Reason for questions:

- The reservoir's main purpose is to hold fuel around the pump in low fuel conditions, for dynamic handling, start ups & start ups on grades.

yep, and trust me on franknpump two i am going to take the time to seal around the sock where it exits the bucket. this is just a test / learning experiment!
- Cutting the hole in the bottom has now prevented the reservoir from ever filling up, it seems like a significant sized hole, bigger than the inlet flow rate of the reservoir j/p can keep up with anywayyes, but before in certian situations you could slosh the gas out of the top of the bucket. that i am going to address also on pump 2. right now i am 25 miles past yellow. no issues. even did a full redline up to 4th.
- I would expect that you would see longer crank times during low fuel start ups & starvations issues that were fairly prevalent before may now become worse

the crank is noticeable but not that much.. so far so fun..

Above is what I would be concerned with, but I have been wrong before. If it's been working fine that congrats!

Swoope was having track starvation with 3/4 of a tank.
his problems increased to the point that the car was stalling (fuel supply issues)during everyday driving--normal stuff.
The sock you see is an attempt to get a bigger sock on the system and to go with a 70 mic size versus our small 30 mic version.

Cncerning the can/sock itself--- i have done a couple of things
1 plastic surgery type needle (approx 70-90 mic size) punched a bunch of holes into the oem sock. in testing pase now
2- the can has a channel in it that flows per venturi fuel to the outside of the can. I closed that up so the venturi only emptys into the can.
3- the top part of the pump assembly is not far from the top lip of the can when you compress it to install. That plus the fact the assembly is almost up agaisnt the front drivers side gas tank wall does not promote fuel going into the can. If you look at the top part of the can a lot of it is actually sealed and there is not a whole lot of room for fuel to get in. SO I notched the fron lip of the can to promote that flow into it. It does help. Can volumne has increased during low tank volumne times. Example my can was approx only 1/3 full when i pulled the pump and there was approx 2 gallons of fuel in the tank itself. After i did the modifications, i rechecked --again with approx 2 gallons in there (just when warning light comes on) and the can was almost full. I had as many controls in place as casually possible.
Seems to have had a positive affect. Now where it has helped with the issues--I dont know yet.
Whats the cost on fuel pump testing?
I will be at Mazmart 1/31 and he has an 09 pump and I cant wait to see it.

mine is doing great so far---but you know it has only been at RR turn 5 that the problem exists---well last time it was turn 3 also--a little.
Swoope see ya Saturday morning--my trans is now doing fine!!
