Haisley's BIG injection lines Q's

[BWillard]

I was looking on Haisley's website at the bigger injection lines and thought somebody else on here might be using them on a 24V. Other than the obvious, what effects will they have at an idle? Rough idle? Will it be too much or, because of "pop-off" pressure, they will have no effect at idle? It says that . 120 lines are not recommended for 24V's because they will not idle! I would like to talk to them about it, just figured I'd ask here first.

I don't believe you'll be a happy camper with larger lines. . you'll expierence an idle issue for sure. . our little VP can't keep the lines full... great for P Pumped motors but not 24 V's IMHO

If you must, only go the 1st step size or you'll not be happy. . also don't do cross over tubes and lines at the same time or you'll play he ll figuring out what going on

 

[BWillard]

Willyslover, I follow what you're saying, but why do you experience this? You're not upping pressure, you're upping volume! Others have said that the VP44 is capable of high HP. I am definately a P-pump guy, but I thought a VP44 could pump a good bit of fuel through it before it wouldn't keep up. Does anyone know what size the stock lines are in comparison?

I had the . 093 lines and . 093 tubes on my truck for about 50 miles. It sounded awesome at idle, but would frequently die when I pushed the clutch in when coming to a stop. I had the origional lines put back on and left the tubes in.

Awww.. .come on, Dan...



A few stalls every now and then is an easy sacrifice for a lopey idle!

Maybe the . 093 tubes with the . 084 lines would be the ticket I think I might try the tubes anyway.



ROADWARRIOR, How much of a lope do you have now, and do you think you gained anything with the tubes?

THATS WHAT I TOLD HIM!!

 

[mdivincentis]

Would I get a lopey idle on my 12v with some . 093 lines?

Matt,



It didn't seem like it when I lost power brakes and steering coming down a off ramp pulling a trailer.



The . 084 lines may be the ticket, haven't tried them yet. I only get a slight lope with the tubes and only when goosing the throttle in neutral or pushing in the clutch. I could tell they added some power.

Correct me if I'm wrong but if you increase the ID of the line or tube you increase the volume but reduce press, delaying injection timming. Opposite affect if you reduce the ID.



The VP44 can produce more pressurer than the P7100 but the P7100 will flow more than the VP44. Average pop pressure on 12V injectors is 260 bar and 24V are at 300 bar.



I can see bigger lines helping at the higher rpms but hurting at the lower side. Pick your sweet rpm range and see what comco will help you there, bigger is not always better. Be nice, I been away from TDR for a while, not up to speed on every thing.



P. S.

Where is Spell CK?

i just got a set of ss. 120 to install on my toy i will tell you how they work out.

I'd like to try the bigger lines before I had to pay for them. Just to make sure they were gonna work. Also, with the lopey idle, is there any problem in the winter time when it gets really cold?

Damn, Dan! I might have to re-think installing them there parts if'n I was you too...

Well, I put in the . 093 tubes last Friday and haven't made up my mind... ...completely if I like them yet. First, let me say that I do think it made a small power improvement. I DO have a little more smoke (which doesn't bother me) on 1x5 than I did before. Second, if it does give a lope, it is very little..... hardly noticeable. I do have one thing I'm concerned about. When I opened the pack of tubes to do the install, I noticed that the one tube had a messed up end on it... . right where it seats in the injector I figured that it wasn't enough to cause any problems though. So here is the situation, If in fact one would get fuel in the oil (if it was to leak past the injector), what would it do to your oil pressure? I know what would happen to the cylinder walls. I have checked and re-checked the oil level and it might be a little high, but the last time I changed oil, I poured in what I always do and did not final check it on the stick because it started pouring down rain. Anyway, heres what's going on, My oil pressure at startup is fine then it starts creeping up to the line above 40 within 10 minutes or so When I start the truck up again it goes to 40 as normal, and goes up again after some time??? Yesterday, it was fine all day Could it be a sender and just coincidence? Other than that, the truck runs fine, sounds good, doesn't miss, and I smell no fuel in the oil. Any thoughts?????

 

[BPonci]

Sounds like a coincidence to me. If you have fuel dilution in the oil your pressure drops due to thinner oil.

 

[P Madrid]

A damage connector tip leads to an Inj miss or poor fuel metering. The copper washer at the inj tip and O-ring on the body is what keeps the fuel in the head passages, if those were not disturb you should not be getting fuel in the oil.



A dripping Inj will dilute the oil.

FWIW I've tried . 093 and . 084 lines and lost hp with both. The truck ran like crap with both also.

 

[jtisdale]

Wouldnt fuel in the oil cause the oil pressure to increase? Willard, have you sampled your oil to see it indeed you are getting fuel in the oil?

Everyone I have talked to have said the bigger fuel lines create a little more hp in the mid range and on the top end, along with the nice lopy idle.

 

[diesel4power]

If the end of the tube didn't seat correctly you would probably know because your engine would run rough or be hard to start. I once very slightly nicked up the ends of about 3 of the 6 tubes doing an injector install and the truck would not start for nothing. New tubes fixed the problem.

Well, I really watched the oil guage on the way home tonight and this is what happened... ... at startup, it went directly to 40psi as normal, as I started down the road as the temp came up it was rock steady at 40 psi! About ten minutes into my trip, a car switched lanes right in front of me :-{} and when I let off the go pedal to avoid the tearing off of the backend of his car, BAM!,oil pressure started to climb to the next line on the guage and stopped dead For the rest of my trip home it stayed right there, never fluctuating, never going back down! When I got home waited a couple minutes, checked the oil... ... right where it was before Then I started it back up just to see where the guage would go, and it went straight up to the higher mark #@$%!



So I got to re-thinking about this, and when I was going for the #6 tube, I was kinda tuggin' on the harness a wee bit for clearance for the 19mm wrench to fit on the line. I just wonder if that oil sender wire doesn't go through there! Does anyone have comfirmation of this and maybe the color of the wire?
