the tsp is a 255 walboro...what is the LPE?

what should I get?

should I also get injectors just to be safe? I'm planning on doing a 150 shot

I can only say what I have, not what you should get.
The LPE pump is a Walbro, it does have a #, I seem to remember 270 or 370. LPE told me it was modified to fit the GTO, not sure if I believe, but I do know it was a perfect fit. The pump itself was not enough for my system, I had to get a Kenne Bell BAP to boost the voltage. This boosts/keeps my pressure where it needs to be when spraying only.
I put the the car to the extreme test a few weeks ago (sprayed up to 165, which I will never do again) and fuel pressure was fine throughout. I figure if the system can take this, it can take any 1/4 run.

i have the tsp kit, its a walbro 255 its been good for me, spraying a 150 w/ bolt-ons......and if your spraying a dry shot, go with some 42# injectors, unless you think you will go even farther with it, then get 60#'s

just wondering who had the bigger pump if there was a diff

 

[SteveNaz]

I think the diff is the aluminum bushings, as the lpe comes with them and the other do not if I'm correct.

Here is your answer.

Slight modification to the sending unit required. Save the 60 bucks and do it yourself and then you are really hotroddi'n.

Do you max your bap? I did last week at the track and blew a pump fuse (15a) Ever here of this? I could not get a full run on the N20 without the bap on 100%. I ordered a 225 Walbro and will be installed before the next visit.

Mine is set at max all the time. I ended up hooking a relay to the N2O activation switch so that it's only active when I'm going to spray.
I put a 30a fuse in the fuel pump slot under the hood, haven't blown any fuses yet. The instructions that came with mne did recommend putting in a 30a and included the fuse.

I thought of that, but the smell of burnt wiring lasts a long time.

It's was slight concern of mine too, but I wonder how much this happens with as many people have BAPs and they actually recommend it. Though Fords may have thicker gauge fuel power lines, I'm not sure.
I don't really know the capacity of the stock GTO wire, it does look thin though.

I'll call around.
I may run a dedicated power line back there in the next few weeks if I here negative thoughts.
