DSE Gas Tank Install Question

[68 SuperRam]

Purchased a DSE (Rock Valley) Minitub tank (with built in LS fuel pump) to go with my Accel Superram fuel injection.



Reading a lot lately about not using regular braided lines (fuel smell) and better way to go is to install Teflon braided lines.

Going with Russell Powerflex - pre-made crimped hose ends to run the entire length of the car:

Since I am going with a Teflon hose - I have not see any hose ends that at 90 degree SWIVEL to a 3/8 npt - they are available for regulator braided hose but not Russell Power Flex (and I also checked with Aeroquip for their Teflon hose).

I found this - a brass 90 degree male and female ended 3/8 npt fitting - made for transmission lines:

Plan is to use this install on the top of the tank then use a regular aluminum 3/8 NPT to 6 AN Russell fitting - then above noted pre-made hose the length of the car.

Just looking for any thoughts or comments if ok to use - Thank you

Russell 660840 is 3/8" npt x -6 90* They will both swing in there, no need for swivels. -8 will not, for future reference.

Have you confirmed your pipe size? I thought they were 1/4" npt.

I tried those parts first unfortunately - one I think can fit - but gets kinda low and starts to hit the pump ring flange - but the other one on the return side - will not turn as it hits the other 90 degree. The 3/8 NPT inlet and outlets are too close together, and the recessed area is only 1 in lower than the top of the tanks.

I spoke with Rock Valley they recommend the swivel to keep the clearance low and told me the 3/8 npt size and I confirmed when I got the tank, The specs that DSE and the sheet that came with the tank said were 1/4 npt - but were wrong - RockValley confirmed the 3/8 NPT size and 3/8 vent line size.

I tried this - but once in - it sits higher than the recessed area - option to put some kind of spacer in there to lower the tank - but would prefer not to if possible:

Would the brass be an issue you think?

[dontlifttoshift]

The brass isn't an issue, I try to avoid stacking fittings like that if I can, that's all. The brass isn't ideal for flow either but it is really not much worse than the standard 90* AN NPT adapters.

There is not a standard for AN adapters, some are shorter than others. I have used Russell and Phenix adapters and swung both 90s in.....you do have to cheat sometimes, clocking the first fitting to allow the most room for the second fitting to swing all the way around.

Past that, I would use a fitting equivalent to the part number I listed earlier for the pressure side and use the brass 90 with a NPT to AN adapter on the return.

Thanks for thoughts - my thoughts also using the brass on the return side and the AN adapter on the feed side. Still trying to research on any other options.

why not use the stock fuel lines and only use braided fuel lines from the hardline to the tank and another hardline to the engine? Seems like we have a lot of people over thinking this. Get this, pipe bender, flare tool, and a vise.

Thanks - gone down that road - and unfortunately it did not work out for me - with my setup - too many re-bending of the pipe and I went with the SS - and it was a pain to try to flare.

I have just cut the ends off SS stock lines & used compression fittings. Then ran teflon stainless braided lines to tank & fuel rail.

[68 SuperRam]

Thanks - I was always told (or read) to try to stay away from compression fittings on brake lines and high pressure fuel injected applications. I guess I rather make sure that nothing would fail or lessen the chance that something could fail.

Get yourself a good flaring tool and your good. First time i have ever done it and it worked perfectly
