Sniper EFI continued

Did a little fiddling today getting ready for spring. Was going to pull the intake, cut the divider and install some tunes i will get from a forum member. Noticed a low fuel pressure situation that i am working on. The question i have is is anyone here running an OEM style pump? Pretty sure my car has a Tanks inc. tank with a separater sending unit hole. If the pressure problem turns out to be the pump i would like a more reliable option than the aftermarket. This car is a cruiser and i value reliability more than all out performance. I have a sniper 1 with internal regulator.
Thanks in advance for the input.
Pete.

it should.
And the internal regulator was a problem area on the original snipers, I would not use that at any cost if you want reliability.
Send me a pm with your email. I’ll respond and then you can send me the global cal you have in it now if you like.

So use an external regulator? Pretty sure I already sent you my file. I was going to fix the issues then proceed with the tunes. Was going to hit you up once I had the issues worked out.

Ok. Good idea, fix what needs to be fixed first.
And yes, use an external regulator.

By "factory", do you mean the in-tank pump that Tanks, Inc sells with their tanks for fuel injection?
They're not necessarily bad. In-tank pumps typically live long lives because they're submerged most of the time. Don't run it dry. The main draw-back is the tiny bucket thing that most manufacturers, including Tanks, slap on the bottom of the pump to act as a buffer and hold some fuel when the level is low or the car is moving around.

You can go waaaay down a rabbit hole on this stuff. The simple answer is just don't go below 1/4 tank and you'll never have problems.

Looks like a bad gauge. This is at cold idle.

So would you run the pump discharge to the regulator, return to the tank from the regulator, then to the fuel inlet (driver side), and gut and cap the internal regulator and return?
