Aftermarket fuel system

[kaboom10]

I have converted my stock fuel system to an aftermarket one. The stock gas tank has been replaced by a fuel cell packed with anti-slosh foam and the cell is made out of plastic. The fuel lines are a rubber lined stainless steel braided line. The fuel pump is also an aftermarket unit that can cover the twin turbos thirst.My questions are as follows. Will pump gas cause any problems with the cell foam, the cell itself or the fuel line material over time with the current amount of gas/alcohol mix? I have run E85 before when the fuel system was stock but now can I run E85 again without worry? One last question. Can I use your products and other's like fuel system cleaners without worry. All this comes about from the fact that race fuel cells are made to work with race gas and over a short season not in a daily driver.

My son routinely does this with show trucks. Doesn't run E85 but E10 has zero effects.

I'd get with the mfgrs and specifically ask...

Alcohol based fuels generally attack the fuel cell foam. Call the manufacturer. Alcohols can attack certain rubber compounds in fuel lines. Call the manufacturer.

Only the manufacturer can answer that. There's no reason that a fuel cell such as you describe could NOT be 100% alcohol compatible. But it could also be incompatible allowing use of cheaper materials. Nobody here can give you a concrete answer unless they knew every detail about the parts you used. Just contact the maufacturer.

Only a materials specialist can tell you if the foam is compatible with E10 fuel. This includes the gasoline component as well as alcohol. The second question would be, for how long are the materials compatible?

Thanx for the tips. I got it from RJS who used to be located in Hazel Park Mich. but I could call them and ask. Kestas where u located at? I'm in Royal Oak.

I live in Livonia for the moment... moving to Highland.

Hope you have a safe move. Never want to live in Wayne county any more. Same for Macomb.

Finished up the fuel system and truck fired right up even after the fuel being a few months old. The fuel pressure is now 53PSI. That just makes the injectors think they are bigger than rated. Weather is so [censored] I will wait for spring to put in the new fuel rails, injectors, fuel pressure regulator and plumbing. Will be putting in injectors twice the flow of the 24 pounders thatz in there now. That should support the twin turbos going in next spring.

Only 53psi? What is the normal spec? Reason I mention that is that many OEM GM V-8 FI systems require 53psi as a minimum for the injectors to fire. In cases of "extended crank time" and a failing fuel pump module, you can watch the fuel pressure build slowly, then, when it hits 53psi, the engine starts and runs. Just curious . . .

On the fuel cell question, I would think there might be some exterior color code or other markings of whether it was built for gasoline or alcohol use. Or perhaps they build one that works with both? Might be some info in the manufacturer's website?

This is a Ford setup. 43psi is normal I believe. The new pump over powers the stock regulator. I have to finish the system by installing the new fuel rails and regulator designed to work with the new pump. I have only run the engine to check the system worked. I guess I will have to call the manufacturer then. They used to be within driving distance but were bought out and moved.
