How do pick a fuel-pump?
I am trying to figure out which fuel-pump that is sitting in front of me is the better choice for my 87 modified(Heads,cam,headers,lrg intake&runners, lg TB and 28# injectors). I really don't know about their flow numbers and can't find anything useful. The first is a set up that i got about 3 years ago from a place called racetronix http://www.racetronix.com/RX-C4369-FPKG-2.html
showing a number of Walbro GSS340M on it(the M was obviously engraved later by some-one). The second choice i don't have a clue how i got or when; it is a DRM stickered box but also Walbro with only a 516 in the part number area.
1)Which of these would be better and should i use the wire harness shown in the link above?
2)I am paranoid about adding a ground strap straight from the battery terminal to the frame...Any input on that?
3)When removing the sending unit assembly i found that the ring at the bottom that secures the pump in place had completely fallen off the return line. Can i get away with just using a large stainless hose clamp around the partial band half way up the pump body to secure it in place? Or, will this create any hazards? I don't want any fires!
Thank-you all for your imput.

Vinnie,
I have found some past posts talking about it as a good set-up but no-one is putting up flow numbers or serious comparisons that i have seen. I am trying to decide if it will be too much and if the Doug Rippie one might be better suited to street cars pushing more power. Turns out i was wrong on my injector size. Found the Accel box last night and it says #24??? My invoice showed #28??? I might have traded them or some-thing and forgot. If I could get a clear answer as to which to choose I could give some-one on the site a good deal on the spare. They are both new and come with sock.

Just get a walbro 255 from ape. Cheap, reliable, more than you need.
Unless you need WAY WAY more than 255lph, which your injectors are incapable of flowing anyway, you don't need to beef up the fuel pump wiring.
