i think i just maxed out my pump so now i need to figure out the next step or if i did not, need to find out what is wrong.

here is the set-up

6.0L 225/225 @ 113 .581"/.581" pt70gts turbo livernois kit full straight through 3" exhaust 8psi boost

we finally had a chance to get it on the dyno and at about 4500rpm the fuel pressure dropped quite a bit quickly to 40 psi and we shut it down. i have only a single 255 walbro in the tank with still the returnless set-up.

i am doing a return style setup now but woundering if when im there, do a second in-tank. i want to make sure i wont have any problems latter.

i would do a second. i never drop below 65 psi and im running 13 pounds

yea, hard to say, did this pump fail or did it just run out of steam???

when i drop the tank should i just add one or replace the 2

it is only 3000 miles old

would you wire in both pumps to run at the same time or wire in one to switch on at a certain boost level??

EDawg

allan did mine. they both run at the same time. the rest is in the tune.
i had a buddy that had a pump fail with less than 100 miles

is he feeding them both off the factory harness??

EDawg

yup. theres a post on here somewhere on how to do it with pics

setting it up is easy but just woundering if the harness can handle the draw but it looks like it works

EDawg

have never had a problem. from what i have seen....its done all the time. you should be just fine.

good deal, im going to do the easy return line off the sheader valve with the 2 in-tanks

I would add more power, a relay & 10 ga wire. The pump is nothing more than an electric motor and low voltage will keep any elec motor from peak performance and eventually kill it.
