I may be completely wrong but the system doesn't have much PSI. The Holley blue pump he is running only has a max PSI of 14, so I don't think a return line is necessary.

Am I right?

 

Yeah, you're right. This is essentially a carb fuel system, which doesn't utilize a return line. I have a similiar setup in my car, though I have a fuel cell with a rollover vent and braided lines.

 

im doing a simalr idea but im using a efi regulator to keep my pressure in the n20 kit as close to factory specs as possible so its easier for my non calculating *** to find jets just finished mounting all my **** just need to get it tuned.

 

I still don't know how it will pick up fuel if the fitting is at the top of the tank......can anyone elaborate on this for me.....i ordered the fuel pump yesturday.

 

go look at your tank where the pump is then you will understand.....

 

Just went and looked at my buddies here at work, totally understand it now, but when I do spray I better make sure I always keep that tank full!

 

yeah but dont fill it too much lol...leave it about 2 inches from the top. it builds too much pressure and vapor locks blowing th cap off. i put a expandable pipe plug in the top in place of the plastic cap, and drilled the hole for the vent bigger and put some vaccum hose in there to vent it out.

 

seems to be holding a lot beter (i used a 2" pipe plug, but a 1-7/8 would fit better)

 

Thanks, will do. For those thinking about safety, the turbo guys have been using washing res for years for meth. As for a crash, the aluminum tanks would probably fare no better, imo.

What if you ran a hose from the place you tapped into the tank to the bottom of the tank to pick up there instead of the top?

Does that make sense?

 

yeah but what would you do with that hole where the original washer pump went? thast why i used it. it was already there

 

exactly and it would be more likely to spark instead of bust/break and jsut leak out

 

Well what I mean is keep the same location you did, but have a hose run through that hole and down to the bottom of the tank...get what im saying?

 

yeah i completely understand, i mean you CAN do it that way but i just thought it be better to do it the way i did so i didnt have to worry about tubing in the tank

 

oops didnt read the whole post lol. yeah i thought about doing that but didnt want it fallnig off or worrying about flakes of epoxy coming loose and clogging up the filter

 

sooo how did it turn out????any update...I ordered everything to do this lat nite....Ill be using a screw on cap though....
