FASS Fuel pressure

[jwilliams3]

Well after running the FASS for several months now, I finally got around to installing a Westach fuel pressure gauge.



I mounted the sender right on the 1/8" drilling that is part of the FASS housing.



Idle is 15psi, cruising about 15-16psi.

Under throttling condition the FASS does not pull down, it stays right at 15psi!!



NICE!



What a great product.

Is it noisy?

 

[jwilliams3]

You can hear it.

But it is in no way annoying, just sounds like a lift pump on steroids.

You cant hear it going down the road.

jwilliams,



Thanks for posting. I installed the DPP pump (only) a couple months ago. Of course, I soon wondered about the pressure data you posted above. Nice to know pressure is good. By "throttling condition" did you mean to say that pressure stays @ 15-16 psi under WOT?

 

[jwilliams3]

I did some WOT stuff it didnt even budge.

A friend that has a 2000 24V (470rwhp) and his fuel pressure wont come off of 15psi under any condition.

fass with in tank pump?

I am considering fass for two reasons Ilike the better filtration as I run in baja alot and would like to go 2 micron and I wonder about the reliability of the stock pump over time as Ilike to explore remote locations and would like to plan on being prepared to fix myself . What did you do with the in tank pump?

We dont have in the tank pumps on our trucks ( unless u installed one aftermarket)

If you are talking about the stock lift pump, it is bypassed. FASS is plumbed directly to the VP injection pump.



Hope this helps,

VP injection pumps

Woops didnt notice this was the 3rd gen forum, got on this thread on a search on FASS.
