What are you going for 2000 PSI rail pressure ? You convert to DI and not tell anyone ?
Kinsler's new Tough Pump looks pretty impressive. I may have to give them a call.
I was going to up the pressure a little bit. 60lbs to 80lbs, I need to do some testing to see what fits the bill. E85 is on my list of to-do tunes and I just figured I'd need at least 30 to 40% more pump than I have now. I really wanted a single pump system, for engine safety. All the electric options were extremely loud and they build up a lot of heat. Weldon has some nice new electric pumps that can be modulated with the ECU but I just figured it was time to get serious about my fuel system. It's been on Santa's list for a while.

Got it. That wouldn't be my core specific route but to each his own best of luck Buddy ! Keep us posted.
I'm going to do a race gas tune and then I may try E85. It's certainly not a priority but I keep hearing good things about it. It's also available at the pumps near my house.

Right on ! If I had access to it I would follow that path but I don't. So I just stick with 110

The Matech tank and ours are in the stock location, but ours for sure will not allow all the water pipes to run down the tunnel as they do on the stock car.
Matech's GT3 tank is 120 ltrs or so and takes up a lot more space in the trunk than the stock tank.
Ours is 100 ltrs for the E100 fuel and 112 ltrs for the E85 (3.78 ltrs to the gallon)
Any way around a fuel cell is around $5,000 made to measure or other wise, they are all pretty much one of hand made units, then you will need a front bag structure, lift pumps, collector pot, and main pumps. And a good amount of effort.

Most racing systems will run 3 or 4 lift pumps feeding a collector pot within the cell, which would then have two Bosch HP fuel pumps within it one as a main one as a reserve/backup.
The return from the regulator then feeds back into the collector pot.
When we got into the stock fuel tank and removed the pumps it appears that one of the stock fuel lines was cut to short at the factory. It should have made a nice round turn but instead it was partly crimped. This was the likely cause of the fuel shortage on my car. Which explains why other 4.0L Whipples did not see dramatic fuel issues. I am still moving forward with my mechanical pump plan. I will keep you guys posted.

Mark i totally missed this thread, I have a full system i designed with a belt pump, tank, return system, fuel rails as im going to run e85 and e98 and make alot of power. It pretty trick the factory pumps feed into a 2.5 tank on the passenger side infront of the rear tire, Belt pump pulls out of that tank and feeds into rails and then the regulator is mounted on that tank and the fuel returns their. The tank @ some point will become over full so then there is a -10 line that returns back to the factory tank. Essentually the factory pumps will just freeflow into the tank. I made alum fitting that goes into the factory fuel line right before the filter and then it goes into a aftermarket filter before entering the new cell.

That sounds like a pretty cool system. We have already begun routing the fuel lines on my car. We decided to remove the factory pumps altogether. The Kensler pump will produce 60psi at 300rpm (if needed) so I hope we don't any startup issues. If we do have problems with startup it will be easy to add an electric primer pump outside the tank. We attached the new fuel pump to the oil pump shaft (so no additional pulley). Vapor tank was discussed and may still be needed but the factory tank design is pretty neat and should deal with pickup and vapor issues well enough. I will monitor fuel temps for a while to make sure we don't see anything crazy.
Did you have any "street-ability" issues with the mechanical pump? I just haven't seen any modern street cars using this type of setup.
ok being the stock fuel pumps suck from all the other areas of the gas tank, how are going to retrieve fuel from those areas without keeping your tank mostly full all the time? Also if you mounted the pump to the back side of the oil pump how did it clear the cast motor mount with out cutting it up? I made a new rear cover for the oil pump and a new shaft. Then the new cover also supports the new fuel pump which is mounted along side of the oil pump. SO there is a pulley at the back of the oil pump and on the fuel pump with a short gilmer belt. I didn't want to cut the motor mount up. Btw it should start fine with the pump alone, i have ran a belt pump on my race car for years and even 6 months down the road it starts right up..
I'm still using the stock fuel pickups inside the tank, just removed the pumps. I'll post up some pictures soon. The kensler "tuff pump" fits on the oil pump just right. It sounds like we used the same location as I also used the oil pump cover as a mounting location. The original shaft is thick enough to support an end fitting that the fuel pump will bolt right up too.
