FPR Suggestions? Boost Dependant? Rising Rate?
What do you guys suggest for a Fuel Pressure Regulator....
I need one shortly and was wondering which one you guys find works best, i was told to look into a rising rate FPR?...
Thanx!...

"Rising rate" normally implies a higher ratio than 1:1.
Even at 2:1, at 15psi, the RRFPR is trying to keep the rail pressure at 30psi + 40psi = 70psi!
Most of the RRFPR's are higher than 2:1.
Get a 1:1 FPR and call it a day.
That's what the stock unit runs at.

It's a popular low budget mod in Australia.
If your planning to stay within the 12PSI practical limit of the TMIC, an adjustable RRFPR with a rewired 255LPH pump will allow some tuning.

its a ratio.
Actually its pretty self-explanitory. Its a 1:1 rising fuel pressure regulator. Meaning your fuel pressure will raise from its base pressure 1X for every 1X of manifold pressure. (because it gets its signal from the vac/boost of the engine)

so basically get a 1:1 FPR and call it a day like everyone's been saying?...
but, there's a normal FPR and a rising one?, or i should ask....
is a "rising FPR" different?...

what about the PD elimination?
do "certain" FPR come with built in PD's?
im running the parallel setup VIA REted's page and i was wondering about htis??
sorry to thread jack.
if there are certain ones, which one to get??
aeromotive?

The standard is that "boost dependent" = 1:1 and "rising rate" is anything higher - like 2.5:1, 5:1, 7:1, 10:1, etc.
Most people will use those terms like that.
You don't want a rising rate FPR, cause it puts too much strain in the fuel pump.
Most fuel pumps don't like going over 70psi or so.
Your T04R is a waste to run under 15psi.

soooooooo, what your saying is to get a nice "boost dependent" FPR, like the Aeromotive, correct?...
i was told to get one that adapts an 5/16 fuel hose/line, with the Aeromotive one 88rxn/a had posted with a link, would that one work, or are -an fittings a whole other ball game?...

Yep, I prefer the SX unit myself.
The SX FPR uses -6 AN fittings, so it adapts well if you're using all -6 AN hoses and fittings.
The Aeromotive unit is very similar.
