Finally worked the bugs out of my fuel delivery and was able to flog the hell out the boat for a few days. New problem came up though. Just had my BG pump rebuilt (by BG) and now when I back out of it after a WOT pass I lose pressure and slowly die. Pressure comes right back up after I die and it fires right back up. I first thought that I didn't have baffles in my tanks but I think it's pump related since it wasn't occuring before the rebuild. Talked to BG and they said to check the by pass pressure but not much advice after that. Anyone else encounter this problem and have any advice? :frown:

I had problems with BG Pressure Regulators too....Would not keep steady pressure.. I run a Holly mechanical fuel pump, thought it was the problem...Turned out to be the Regulator.....

It's not the regulator for sure. There is a non regulated gauge at the dash that mainatins 12 to 14#'s pressure reading from the pump, gauge at the fuel log is set at 7 #'s after the regulator.
When I back out of it after WOT the dash gauge starts losing pressure and I slowly die and have to restart. I thought I was losing prime at the pump and thought that might have to do with the rebuild on the pump maybe drawing more efficiently and sucking a little air. I talked to the guy that rigged it in it's current condition and he said he never had that problem. BG said ther eis a possibility taht the pressure on the return is out of adjustment and needs to be at 17#'s. They didn't tell me if more or less pressure than that would cause this problem, they think the fuel may all be being diverted to the bypass and back to the tank.
I was wondering what pressure I should set the by pass to if this is the problem?:frown:

Yup.... It was the Red By-pass regulator... It Fluctuated 3-4lbs. We now use the Moroso Fuel Log/Regulator combo deal and have No problems.....

We run one on the race boat had probs at first sounded the same.They have to be mounted below the tank to work best as they do not suck to well but push very good.Ours is a 220 model.I think our tuner also turned up the pressure on the pump itself.They are finicky from what i learned but once set up correctly they work fine.Just to much work to get right IMO

Talked to another tech at BG and he said to just adjust the pressure higher at the bypass and that also increases the pressure to the reg. Good excuse for another test and tune at the river.:D
Can't really comment on my satisfaction with the pump(220) since it was in the boat when I bought it but the reg has always worked fine, doesn't vary pressure at all.
BradP, I talked to Barry Grant about there pumps & the 220 pump is not a continuous pump. They said it's for 1/4 mile only. They also said if I didn't plumb it like there diagram, and put the check valve after the carbs for the return line it wouldn't work! Not only that the guy got kind of shitty about the whole think! I told him to f*ck himself and I was on my way. If you go to there web site you can get the diagrams.

Maybe you should go with a better setup, like the MagnaFlow Pro Star 500 or an Aeromotive!!

i'd love to do that , but unfortunatley i've got about 800 dollars worth of their stuff , so it better frickin work, hud, you said the 220 wasn't a continous pump?.. what do you mean? i was told it was a continous preset 15 psi?..
blownmoney, I ask BG if I could use the 220 pump for lake duty and they said after about 2 mins. it would start to get hot & possibly damage it. A Mallory 250 pump is a continous pump that you can run 24 hrs. a day. BG has came out with some new pumps that are continous!

Same thing happened to me! I had bought a used 220 with a BG 2-port regulator. After talking to BG, I wound up running a Clay Smith mechanical and the BG regulator, which leaked from the begining. Since I had already plumbed in the BG, I bought a brand new BG and it doesn't hold pressure consistantly. The freaking gauge is all over the place!
I'm not impressed with BG or thier customer service department :( .

They make two different 220 pumps, one has the by pass built in to the fuel pump body and needs a return further down the line. The one with the built in by pass is suppossed to be continuous.
I didn't want to bag on them since it's a used pump when I bought it but their customer service does suck big time.

The best pump money can buy is only 100 bucks.
These things never fail.

Got one on the bench. Boats rigged with a return at the tank and a gauge at the dash for the electric pump so I need to keep it or an =. If this isn't the problem and I do need a t-tank I'll feed the tank with the Clay Smith mechanical.:D :D

That's what I heard too. I've got no complaints so far(1/2 a season of run time).
