shanehutton Posted November 7, 2020 Report Share Posted November 7, 2020 Currently having issues getting 2hrs out of our tank and would prefer not to spend on a cell if possible. at the moment, we get about 1:40 to 1:55 depending on the track with a stock tank and a 2L surge tank. For those of you that have run a similar setup and added a hydramat, what kind of improvement did you see? Is it only really an advantage for those who don’t have a surge tank?

turbogrill Posted November 7, 2020 Report Share Posted November 7, 2020 We run both. That way you get all the fuel without interruption and also a little extra capacity. Bonus is you can add a level sensor in the surge tank for a very accurate low on fuel indicator. On our NC with great tank design the hydramat helps a little but not 15 mins, but on our datsun it would have helped since the tank sucked. What car?

shanehutton Posted November 7, 2020 Author Report Share Posted November 7, 2020 Car is an EK chassis Honda Civic. We already have a float switch about 2/3 of the way up the surge tank that triggers a light on the dash. Quote Link to comment Share on other sites More sharing options...

If the light goes off then it means that it's more fuel that the stock pickup managed to pickup. If so a hydramat might help It would think that the stock tank does a good job picking up all the fuel when you are standing still.

wvumtnbkr Posted November 7, 2020 Report Share Posted November 7, 2020 We run a stock tank that we made sure the pickup was as optimized as possible. No hydramat. We run a fuel filter type surge tank. No problems picking up the dregs of the tank... 1 Quote Link to comment Share on other sites More sharing options...
JDChristianson Posted November 7, 2020 Report Share Posted November 7, 2020 seems like the first question, is... When you are "out" is there still fuel in the tank that isn't being picked up? If so then a hydromat may well help. We have had good results with on in our cell. It gets all the goody out. Quote Link to comment Share on other sites More sharing options...
shanehutton Posted November 7, 2020 Author Report Share Posted November 7, 2020 Yeah. I think I need to pump it out with the in tank pump and see how much is left. 1 Quote Link to comment Share on other sites More sharing options...
Members MR2 Biohazard Posted November 8, 2020 Members Report Share Posted November 8, 2020 I have a hydratmat in my stock tank now and got the longer cross shaped one. I can now use up every drop in my tank and every little bit helps. I converted to an external fuel pump and a walbro inline pump. This pumps through a large WIX filter to a custom surge tank. I used 3.5" (3.25"ID) alum tube that is 12" long with 4 side npt fittings, one at the bottom and then three towards the top. The top I drilled a hole in it (prior to sending it off) and the drilled tapped the holes for the sending unit. I had Kevin Smith from KSR Tig weld it up for me. I made it long and skinny as I installed an aircraft sending unit and gauge on it. The sender also has a warning light you can wire up and I use a yellow warning light. I set the warning light to 3/4 of tank to come on. You have that lap to come in or else. You have to calibrate the sender, set empty, set full, set alarm, but it is pretty easy to do.

TiredBirds Posted November 10, 2020 Report Share Posted November 10, 2020 swinging pick up can help.. what happened to us was on hard turns the line would suck air until the gas sloshed back causing a buttterrible stumble going down the straight, not a good place to have that.
