So I plug the bypass off at my cell and my pump gauge and my dash mounted gauges both go past 15+ psi. So if my pump was bad how that be possible? It`s too late to call Aeromotive so I`ll phone em tomorrow but Cab had mentioned that it COULD be the relay............wadda you guys think? Thankxxxxx.........

Regulator, not relay. Sorry for the background noise on my cell phone It worked okay for a while, something is dying or getting FUBAR Let us know what you find out

Sounds like a regulater problem. A relay if its failing will burn itself up pretty fast.

Does the Pump itself seem to run at a constant rpm.

Make it a dead head system sounds like your using the wrong regulator for a bypass system.

The pump seems steady enuff but when I bypass it the pump and. reg. maintain about the same pressures.....like if I set the reg. to 8 psi, the pump shows about the same WHEN bypassed but the minute I plug the bypass, both gauges peg to 15+ psi.

Does anyone know what that pump is suppose to put
out at max pressure... I would think that it should
be well above 15 when dead headed

Dom, i use mallory 4309 regulators for my junk. i love the design and how well they work. i'm not sure what you are using

---

I use a 4 port Mallory... very simple... a spring and
a seat... I've been running the same one for years

---

Mike you have a p/n for the one you are useing? i am looking for one for my twin 650 holley dp for my tunnelram and am undecided which one to get. thanks Mopar65

No I dont.. not sure if they still make this one...
it also has a boost reference port... when I bought
it I know it came with 2 springs... 1 for carb low
pressure and 1 for injected high pressure

They say the pump should put out 14 psi which makes me think I could run it deadheaded. I`m using the Aeromotive 4-port bad dog reg. but was thinking that when I plug the bypass it not really deadheaded properly so I`ll call em now and report back. Thankxxx guys..........
