I dont understand? You mean use 2 pumps or use stock hanger?

I think he means two, OEM setups.

kikiturbo

hmm, still not sure what is the question..

you can use just my lift pump in the right side of the tank and use OE or any other hanger in the main tank.. just remove the venturi...

EVOFans

Ah ok, now I understand
So basically what your fabrication do is just remove the venturi and replace it with a lift pump from left to right side of the tank

kikiturbo

yes and in case you use both hangers you also loose the stock fuel filter and get higger amp connectors on all sides plus an6 fittings everywhere

Definitely a great idea. Me likey.

What are you doing about running the lift pump dry?

kikiturbo

Lift pump has a float with a reed switch. It switches the lift pump off when the fuel level is too low in that part. I managed to kill the OE pump in testing by running it dry for 5 sec... I am carefull

I think you can notice it in the pic... maybe it doesnt show as it is black..

It was a bit of chore finding petrol compatible floats and fuel tank connectors..

That's great, you might be the first person I have seen attend to that. Nice work.

kikiturbo

thanks, appreciate it..

I did some testing with initial concept, and with the 190 lph pump it just about balances the flow out of the e9 fuel bowl in 1G left turn.

I am just working on the setup for my own car which is a full internal surge tank setup with 4 pumps altogether.. will post that soon..

Have you ever thought about trying some of that Holley HydraMat inside a standard tank?

Jaraxle

Been done, and apparently they don't flow enough because they close due to too much suction/flow. Holley won't report flow rates before this happens. I have my project on hold for the winter, but will be using an OEM lift pump from passenger side of tank to Radium fuel pump hanger assembly which has a bowl of fuel with check valves. I handled the run-dry problem by having FOUR pickups in the tank (two on each side). So if one side goes dry then it closes and fuel is pulled from the other side and dumped into fuel bowl.

Here is the link to that spot in my thread:

yeah, I cant do it as on the older cars we have fuel bowls in each side of the tank areound the pickup...

Regarding fuel, isnt the issue of fuel starvation solved by running a full tank? Are those who have this problem running less fuel due to weight or something? I never really understood because its not like you burn through a full tank of gas in a 20min lapping session.

On E85 I would get fuel starvation on the third lap even if i started the session with a full tank. Of course this is on my 10 which starves way worse than the CT9A.
