Thanks for that information. I can see where space would be an issue, especially with my factory oil cooler lines adding to the mix. I still think I'll give it a go, for reliability reasons.
Ken, I don't think I'll be pushing enough G's to have that issue, but I'll deal with it if it becomes one. I know it'd be wise to keep a half tank full to help keep that from happening, and I can modify the pick-up to extend further rearward, if need be. I'd like to stay away from a fuel cell or welded on sump for several reasons.
Russ, thanks for that link, but I'd prefer to stay mechanical. Electrics just add more complexity and chances of failure. During Drag Week, Freiburger said something that rings true every year: Closely paraphrasing..."The three main issues causing breakdowns during Drag Week are roller lifters, electric fuel pumps and automatic transmissions". I can't even count how many guys had issues with their automatics. I know of at least two guys who had to rebuild their transmissions 3-4 times during the week! I may not be able to avoid the roller lifters, but I can the other two.
Edit to add that it does give some interesting info on the AN sizes required though. Thanks again for that link.
