arent they all built the same? All using stock housings? or no? I do remember when I installed my buschur one there really was no wrong way to install it. it was all pretty self explanatory.


EDIT: nevermind, i see the other pumps are way different looking. mine is using stock housing modified tho with barb fittings.

 

I'm starting to wonder if you know what you are talking about half the time.
First you say all double pumpers can't be run with low fuel. Now you say you had that problem likely due to bad o2. Now you realize the thread you read is using different pumps...come on now.

Op. Did you install the blaqops kit your self? Was it a TIGHT squeez? I know when I installed mine, it was really really tight. I had to bend the sending unit floater a little bit because there was no was in hell it was going in if I didn't. Did you have to bend it also? Maybe that's why you are having problems with your fuel level.

 

ok and your point is? I was unaware the blaqop's was different from other pumps.. sue me? Im sorry i try to help so much on this forum that sometimes I am wrong.

From MY experience and a few of my friends the pump i run will sputter if ran to low on fuel. But as I said the o2 sensor being dead sure as hell doesn't help any of that!

If you have nothing good to post dont post at all. You can research through all of my posts, im a very helpful person on this forum and will continue to be.. I am here to help people not talk down on them.

 

i dont know about all the double pumpers having this issue...ive tuned and raced my car with far less than 1/4 tank before and never had any starvation issues with my br double pumper.......

 

mine hasn't done it anytime recently, but i do recall it doing it in the summer time a few times. I guess it was more so the o2 sensor then the pump. Just seemed odd it occurred more when i was very low on fuel, unless it was in my head.

I remember when I installed it the floater arm got stuck and i had to take it back out again.

 

You don't need to get all butthurt. We are all here to help which is what makes this community so great. I'm just saying it helps to know what you are talking about if you are trying to help some one.

By the way, don't think there is much difference in the location of the pumps between the buschur kit and blaqops since they use stock hangers. They use walbro 255's so I don't see how some kits will run like crap on low fuel while blaqops dont.

But I do agree on the o2 sensor. That should be the first thing checked.
Op, did you have trouble routing the sending lines from the hanger? Maybe one got kinked.

 

Are the buschur kits a tight squeeze as well? Or was it easy to slip the hanger back in without bending the floater.
(by bending I mean just slightly to where it will go in, nothing permanent.)

 

really tight fit. I remember i had a hell of a time with it. At first when I installed it the gas gauge didnt work so i removed it then reinstalled it, then the gauge worked.

I just thought it was partially the pumps fault because i had 2 other friends on the pumper ask me if i have any sputter when i get really low in fuel.

I wonder if its possible that the double pumpers do not register the correct fuel levels and when its a quarter tank its almost empty in reality. I wonder.......

But after I changed my o2 sensor all the spudder went away. Car shifted like butter then as well. The o2 really made the car run like crap to say the least. I posted a o2 sensor thread regarding that as well. My car seemed to not like the walker o2 sensor, so i switched it ot a denso and it ran 10x better. Not sure if I had a defective o2 or what.

 

If anything it would be because the floater is caught up on something. I WISH I could look in there somehow with the hanger in place. I just felt sketched out on how hard it was to drop the hanger back in place. I remember I had to bend the floater a little and twist it in a weird angle. Iv always wondered if the floater is resting in there with no obstructions or if it is hitting anything.

 

Ya I remember I had to bend mine also to the point I got alittle scared. I wanted to be as easy on it as I could. The biggest ***** of the entire install was getting the hoses on tho once the thing is in there. I remember I had to take the entire thing out again just because of the stupid hoses.

 

at what power level do the double pumpers even come in? like to avoid this issue if possible but if not at least im gettin something out of this thread to consider

 

Don't let this thread scare you from buying a double pumper.. if it was that bad it would no longer be on my car. 470whp~ on e85 and im not sure about pump gas. im guessing 650.

 

well my goal is 650whp or so and im looking to do it on 93 and possibly meth

 

Sorry for the late post guys. I had a friend that owns a shop install it when I upgraded a bunch of stuff at the same time. I'll double check it and let y'all know.

TCOMP I never replaced the 02 sensor. And yes i've been running E85 only for the last 1.5 years. I didn't think that could cause the problem but I'll look into possibly replacing it.

I was looking ot buy the BlaqOps unit new but they were out of town until November so I luckily found it used. It was one of the original kits and the guy who owned it before I believe was running a Walbro 255 and a 270 (I think) at the same time......I know its def. not a 255 X2. I didn't think it would make a huge difference.

 

for those of you that are running pump (93) and E85 how are you switching between your two maps dont you have to run your tank low to do so ? i have a full blown double pumper not yet installed tho.
