bg users beware

WARNING BG USERS

After extensive discussions with Richard at BG and my local shop we have deduced possible and highly probable causes in the BG 220HR failure
1. pump must be gravity fed, using pickup tube will cause failure
2. must use 10 an line to pump minimum. We will use 12 an.
3. Regulator must be used in conjunction with a tee (not in line, cap the p/o side)
4. Regulator must be at least at the input of the fuel filter
5. Outlet of the regulator needs to be 10an hose (even though the output is 8an) 10an return hose imperative

Final and foremost BG sweats to me if it would have a good life in any other plumbing situations they would have printed it on the instruction sheet.

Points of Interest BG 200 HR

*is a sliding vane pump (look inside for yourself)
*Obviously it’s not a gear rotor design
*Motor is not fuel cooled

BG and my local shop firmly believe the pump will fail soon unless installed in other method, it must be plumbed according to BG instructions.

Currently, I plan on blue printing the exact fuel system and send it to BG and ask their opinion.

We may try a fuel injected fuel pump and regulated-this is a dangerous proposition as we need to find a victim for this. F. I. life pump=100 p. s. i-please don’t anyone try this without discussing it with us first. I am thinking outloud. Other than the proper BG pump plumbing the F. I. pump may be one of only a few options.

The Mallory 4150 still might be a viable option, however the only member we know of using this pump is our beloved Teflon Superhero HVAC. HVAC never has anything go wrong. HVAC=good premium grade karma.

Our intention is to install the BG on Wiz 1’s truck with his top-secret fuel filter. I will be plumbed in accordance with BG instructions and it will be checked over by BG Tech, just for grins.

More to Follow

P. S. I will start a page on my website for discussion of this. If any one wants to add statements and results let me know, I will cut and paste if anyone likes.

wish I would've talked to this guy first--
man I toyed(in my mind)with the gravity feed thing and should've done it--just haven't quite figured out how I would==so now I'll reopen that door-along with the replumbing--
good job Brandon, eventhough I'm depressed with your findings, but hey I took the shot so now we'll move on and can only think that my problem will help others to wait until this can be worked out ---chris

 

[Bad340fish]

Have you guys tried just the good ole Holley blue pump??? I do not recall seeing it mentioned before. I have one in my car(YES i know its not a diesel) Its not gravity fed and I regulate it with NO return at 9PSI so in turn the pump is pushing alot more than that because I can hear it work against the regulator when the car is off. I imagine in a semi loaded situation as in the VP44 setup it will last a long time. Mine is only about two years old but I know of alot more of them that are way older than that. Just thought I would throw my . 02 in... Good luck guys

Brandon,

Your hero and master of good karma,
HVAC is in my shop right now, his dual disc clutch is toasted, i will post a couple pictures of it,

csutton,
to gravity feed your fuel pump all you need is a bulk head fitting.
I've had one on my truck for a while as i am doing some testing with mopar muscle, between us we've probably covered about 10 different combinations, most of pumps you guys are playing with are off drag and street and strip cars,these pumps never in their application see more than 20 hours of operation a year. On a typical drag car, the pumps are never running for more than 2 minutes at a time, in nascar not usually more than a few hours at a time.

Bill--now don't you go and soup up HVAC's truck too much-he,he,he--I figured Mopar Muscle would be up to something and now you too--that's sneaky(just kidding) but it's great, as this thing needs to get figured out and the more involved the merrier or easier--according to Brandon and his talk with the BG guy, the 220hr has been in a couple of street cars for 7 years and still going---so if that's the case and it can be plumbed right this sounds like a very good option unless one of the lesser($$$$) pumps can do the same---have fun with the RED ROCKET and this weekend---tell HVAC I said howdy--

BAD340FISH--I'm using the black Holley 815 right now and it drops at least 7 psi @ WOT with the PE off(11psi to 4psi) and even more with it on--what model # is the blue Holley cuz I think the black model is supposed to be better thus the blue isn't the answer either--

this whole issue of pumps will take another turn once the gravity feed system is worked out, is what I think, as all electric pumps like to be gravity fed---- chris

Reading through several of the fuel pump threads and seeing the attempts to find a solution brings up a question. Has anybody tried replacing the sending unit/fuel handling module with one from a gasoline injected unit and using TB low pressure (12-15 PSI)in-tank pump. I understand that it will not be a direct swap as there were no TBI 2nd generation trucks, but the LP pump should fit in the same place as the HP pump.
I would think that there are enough wrecked 2nd gens to supply the module for a reasonable price, and the pump should be as close as the local parts store.
Pump access is obviously somewhat of an issue, but then again in-tank fuel pumps aren't something that goes bad on a regular basis. Additionally, inside the tank is the safest place for them, from both a physical damage and fire standpoint. Isn't this is the way GM does it on their diesel trucks?
As someone here has said - pumps are made to push, not pull.
Comments?

bill you are a dog... ... ... ... .....
come clean what is the current steup you are running right now... ... ... ... .....
I still got my secret weapon as I live in Modesto he he he he eth
seriuosly what is the current setup, you are running, especially the bulkhead
we will be doing this to wiz1's truck very soon as soon as all the fittings are gathered
ps how cold is it in canada, I want to know if hvac still wears shorts in arctic climate???????

I agree that a gravity feed is the best. My BIG concern is the durability of the plastic tank with a -10, -12 bulkhead fitting screwed into it. Plastic doesn't inspire the same confidence as would steel or aluminum. Any reports about possible tank cracking due to drilling for a fitting? I just ordered my Mallory Comp 140 pump and I'm getting ready to run new lines prior to "other" accessories.

[csutton7]

I'm going for it and if it cracks well I won't be happy but it will give a reason to buy a bigger tank--probably shoud do that any way---I've got to much tied up into the fuel system to stop now---more fuel!!!!!chris

The bulkhead fitting you want i believe is the style designed to go in plastic fuel cells, instead of screwing in to the plastic, it has a washer and nut installed from the inside. I have relocated pick ups on plastic fuel cells for my off road car, they drill real easy, and no splitting, cracking. The plastic of the dodge tanks looks to be a similar material to me. I found that using the appropriate size hole saw instead of a drill works best.

Chris, I wish you luck with the tank mod. Rubberneck, I've also dealt with fuel cells. The 12 gallon one in my camaro is about 1/4 thick and very well supported so it doesn't flex. Anyone that's seen the stock tank when full knows it bulges/flexes a lot. I "think" this flexing might lead to cracking around the hole for the bulkhead fitting. Only time and a test case (Chris), can answer this question.

Figures DC would go cheap here too. Oh well like chris said, might be a good excuse to get a bigger tank. Phil

chimming in from the north country ... . bill and i have been hashing this one out and i need to check a couplee more things so as not to be branded a YES man ... but the big lines are OVERKILL ... anyone got there fuel pump instruction sheet handy ????? especially a MALLORY ???? read what it says about VOLUME .

after reading it myself today , dodge has the fuel system designed PREFECT for a STOCK cummins that system is also good for a moderately BOMBED cummins .

all i will say right now is increased fuel pressure is because you have a restriction ... the injection pump is that restriction .

we all have spent way to much time and some way to much MONEY fixing something we think is broke , it ain't .
