Thanks tony, the stuff ive always used to seal gasoline is that blue lock block or whatever its called from home depot.  It seems nothing affects the stuff.  Don't get it on your hands because there is nothing that will get it off!

Drilled two holes in the passenger side bottom of the tank(I believe they were .875). You want the bulkhead to almost thread into the tank(basically zero fit) and use a high quality gas resistant sealant on the washers. Drill the two holes in the steel can oversize so that there is plenty of room between the nuts and the can that way you can get a socket on them. Make sure that when you drill the holes that they are up high enough from the bottom of the cell so that when you tighten the jam nuts down the washer is OUTSIDE of the radius in the tank or they will leak! Here is the link to the bulk heads that we used, when I get home tonight I'll find the sealant and post up the part number.

Tony, how did you go about exiting the cell at the bottom?

FYI, i found fuel cell foam rated for alcohol......going to use that.

Are you sure you are not losing fuel pressure? These engines are very fuel pressure sensitive, we had what we thought was vapor lock, turned out to be the crappy black jazz fuel cell foam clogging the filter. Worst part was it only happened under long WOT conditions so it is very difficult to replicate under not race conditions. FYI we gravity feed the pump and run a return off the fuel rail.
Good point Tommy! A differential of 2-5lbs of fuel pressure was the difference in doing a power brake and spinning the rear tires and doing a power brake and not spinning the rear tires in the Elite truck. You need to know what pressure the truck was tuned at in order to get optimum performance out of these hamster cages.

I think vapor lock can be an issue depending on the race conditions and fuel ran. But I think most of the TL fuel related issues come from a poor fuel system design/set up.

Agreed russ, this is what I keep telling people at the races, but for some reason they think vapor lock is an issue!  Who knows what caused it, but it will not happen again!

John that truck has 5k race miles on it w no issues relating to vapor lock or lean out. If you did not lose fuel pressure on the gauge at Parker you did not have a fuel pump related issue. That gauge reads pressure right at the fuel rail.
The temp issue around the fuel rail has been beaten to death. It is this simple. Go rent a GM 4 cylinder 2.4 powered car.
Drive it in 110 Nevada heat up hill as with as much load on it as possible,5 fat girls a case of sparkling wine.
w asphalt temps of 130-150 , under hood temps of who knows but 180 would be easy to imagine .
Cat converter ,exhaust running right next to the fuel tank , fuel tank a few inches above the hot asphalt. 87 octane fuel ,
Do you think it will overheat ? do you think it will vapor lock ?  nope that old fat girl hauler will just keep going.
TL trucks get a ton more cool air around everything except AC up a short skirt :)

Yea, personally i wouldn't go turbo if that class happened, just more to break and im happy with the speeds of the class now....but for some it might appeal.
