Fuel Pump Installation Problem, Cap cracked, please help (supra pump) + (Pics)

[jm1080]

I really need to know if the fuel pump brown cap is really necessary? While putting it on, the cap cracked a bit. This cap:

I can't find this cap anywhere and I need a car by tomorrow

Also I took this pic because I want to be sure that the pump is supposed to be slanted a bit when going on the assembly, I used two o-rings to make a tight seal but it is still slanted and hitting the white connector:

It also sticks out a bit due to hitting the connector, you can see it sticks out where the spacer is, but the o-rings still hold it in place:

Is this all normal for supra pump owners? I really appreciate help, thanks!

I read it but ive never put a supra pump in a dsm. Have you turned it on to see if it pumps yet?

I run a re-wired supra pump. It was a long time ago when I installed it but I remember my pump was on an angle as well and I installed it with a cracked brown piece like you had. My crack was not all the way up the side though ... only the bottom portion. Been running this way since 2003. I have a fuel pressure gauge as well and it shows no issues. Hope this helps!

Thanks for reply, did you happen to use two orings as well? I started it up and it worked fine, turned it on with dsmlink and is nice and quiet. I guess it is working properly. How would you know if it is leaking from there? I set my fpr to 43.5psi with hose connected, and had car off and turned on fuel pump with dsmlink, that is good way to do right? I then adjusted screw to 43.5 and when I drove it it dropped to like 30-34 and when i revved it a bit it went to 37. Hopefully it isnt the brown cap?

I also added a smaller o-ring to the top of the brown cap as a preventative

It can drop, by just driving around, but under boost it has to rise.

oh ok, so it is normal for it to drop while driving around? Thought it was a leak or something, I added teflon and everything even on adjustment screw to be sure.
