revvhappy Posted June 20, 2021 Report Share Posted June 20, 2021 I added a fuel cell and wonder if I can add a small Lexan view port to see the fill hose while refueling. It would seem that sloshing fuel out of the fill hose during refueling is worse than the difference in time between a small viewport and the sheetmetal bulkhead melting. It would also allow the fueler to stop before it fills the hose, which would reduce the possibility of overflow from the vent during early laps after a stop.

Team Infiniti Posted June 20, 2021 Report Share Posted June 20, 2021 I’m not certain lexan can do the job without cracking Quote Link to comment Share on other sites More sharing options...

I don’t believe he’s talking about having it done n contact with any fuel. Just the bulkhead so he can see the clear fill hose. Quote Link to comment Share on other sites More sharing options...

revvhappy Posted June 20, 2021 Author Report Share Posted June 20, 2021 Correct, it would be a small window built into the top of the bulkhead. 1 Quote Link to comment Share on other sites More sharing options...
MMiskoe Posted June 20, 2021 Report Share Posted June 20, 2021 Send a tech desk request. If the answer is yes, I'd have it in writing when you go through tech. Don't bother to ask that here. Quote Link to comment Share on other sites More sharing options...
mhr650 Posted June 20, 2021 Report Share Posted June 20, 2021 There was a topic about this a while ago, the consensus from tech seemed to be no Lexan allowed in the bulkhead, it had to be all metal. 1 Quote Link to comment Share on other sites More sharing options...
revvhappy Posted June 21, 2021 Author Report Share Posted June 21, 2021 Thanks, Mike. The rule does read "metal bulkhead", but I just picked up a 3 year old Champcar that has a bulkhead window and passed tech with it at the time. I'll ask tech. 1 Quote Link to comment Share on other sites More sharing options...
Administrators Bill Strong Posted June 22, 2021 Administrators Report Share Posted June 22, 2021 there is a team that has a sealed door that they can flop down to look at their fill hose. You could do the same, but have the lexan window under? Quote Link to comment Share on other sites More sharing options...
TiredBirds Posted June 22, 2021 Report Share Posted June 22, 2021 ^ that, I don't know any racing body that would allow that. Quote Link to comment Share on other sites More sharing options...
MMiskoe Posted June 23, 2021 Report Share Posted June 23, 2021 Going by memory, but if you don't have a bulkhead between the driver compartment and the fuel you can't have the driver in the car. So if you have to breach the bulkhead to put fuel in the car, then the driver can't be in the car during fueling. Not sure that a trap door to a lexan window is going to fly.

Administrators Bill Strong Posted June 23, 2021 Administrators Report Share Posted June 23, 2021 How many guys open the trunk to fill the fuel? As long as the metal bulkhead separates the fuel fill and stuff from tbe driver it's good to go. Quote Link to comment Share on other sites More sharing options...
revvhappy Posted June 23, 2021 Author Report Share Posted June 23, 2021 (edited) Interesting conversation. I finished building the bulkhead yesterday to race at CMP. A sealable viewing door might be an option but I don't know if I can get one into a location where it helps the fueler. The top access panel will be sealed after the car is goes through tech. The extra large size is due to enclosing both the cell and a diff cooler. Edited June 23, 2021 by revvhappy 3 Quote Link to comment Share on other sites More sharing options...
mhr650 Posted June 23, 2021 Report Share Posted June 23, 2021 Very nice, fuel filler is nice and high and on the passenger side away from driver changes. I would really try to get some paint on it before CMP, don’t want to blind the driver from reflections of that strong SC sun from the bare shiny aluminum….

revvhappy Posted June 23, 2021 Author Report Share Posted June 23, 2021 Thanks again, Mike! Flat black paint will be applied. The piano hinge worked great along with a couple of 1/4-turn fasteners. 1 Quote Link to comment Share on other sites More sharing options...
revvhappy Posted June 23, 2021 Author Report Share Posted June 23, 2021 In case you find this thread later, do not use flat black (gains heat). Use a flat light color paint. Thanks, Kevin! 3 Quote Link to comment Share on other sites More sharing options...
