340lph Fuel pump

Hello, I've been lurking for a few years and have answered many of my questions w the search engine. However i need opinions on fuel pumps.
The #178 has a forged 4.1L, Cam, Everything is ported and has big valves, 66 ptrim turbonetics BB, 3200 stall and is running on ms109. Im shooting for 10's and on the street tune it runs great on pump(90 is the best we have in AK) @15psi and the 255lph pump seems to be adequate. But im looking to up boost n timing (safely in 1 psi and 1 deg passes). Im going to be changing the hot wire kit to racetronix kit. It has the old caspers kit which is 1 gauge smaller than the new and was thinking of putting in a 340lph pump while im at it. Thoughts? Sources? Is the Aero 340 a drop in replacement? Do GN's use the same sending units and hangers? Thanks in advance.
 
I installed a 340 walboro from Racetronix but I never installed the hot wire kit .Everything seems to work well .I don’t think they use the same sending unit or hangers.Any third gen sending unit and hanger would work.
 
What size injectors? Alky?, Have a boost and fuel gauge? The fuel system is one of the most overlooked aspects of TTAs... and the most important, if you are shooting for 10's the biggest question is how many times do you want to do it,, while keeping the car in one piece, if you go lean at that power level you will get a lesson on changing HG's.
 
60’s from turbo tweek.Yes I have both boost and fuel gauges.Also scam master ,running a little rich top of third o2 are around 830,s
 
I was replying to the OP but if you have a TT chip just pull a little fuel at a time till the eng is happy, a PL is even better...
To the OP A 340 OR dw300 will work fine but i would be very careful with timing, personally i would not go over 21deg...
