Summit lift pump installed. Great FP now.

[tmacc]

I've been trying to decide which way I was going to go regarding pumps. Steve St. L's pusher or a 15 lb. pump back by the tank. After seeing HVAC reply to a post I decided to get the Summit G3134 pump and abandon the stock lift pump all togther. After I ordered the pump I saw a post by Amianthus(sp?) about his Summit pump. He also gave me some feed back that was very helpful.



Ron Prothro(Wiredawg) and Larry Willard gave me hand. We also installed Ray's BB in Ron's truck in preperation for his looonngg awaited Westach gauges and drilled out Larry's BB.



I used the Cummins pigtail to trigger a relay to run to new pump. Nothing new there. I used a Weber adapter to run the new fuel line to the filter housing. I used Parker pushlok fittings and fuel line from the tank to the filter housing. When we got everything hooked up and fired up the truck it pegged the 16 PSI Westach FP gauge. During the test drive we couldn't get the needle to move. After hooking up Ron's Mech gauge, it read 25psi. The directions w/ the pump say not to adjust it, but Amianthus said he adjusted his, so we adjusted it to 15-16PSI. Haven't taken it for a test ride after adjusting because the pump was (is) leaking around the 3/8" NPT fitting on the output side of the pump. We tried another fitting to see if that was the problem. Same thing. Weeping around the fitting. Finally wound up putting some Copper RTV on it and I'm letting it set up. It looks like the threads aren't cut deep enough into the pump for the fitting to tighten properly. We'll see.



Leak non with standing, I am happy to have decent FP for a change. The stock pump would go down to 2-3PSI at WOT. I'll post road test results tomorrow after the RTV sets up.

Good post tmacc, hope it lasts for ya. Hard to beat for a $100. 00 if it does. I see that you adjusted yours, just curious if it uses the same type of deadhead adjustment that the Mallory pumps use ???

Tmacc really enjoyed giving you and wiredawg hand, and many thanks for drilling out my banjos. Hope you got the leak fixed now.

Larry, Thanks for your help. Sure turned into a long day, Eh. I think I'll be called Summit in the morning for a replacement. It seems to be leaking around the cover plates on the bottom. Might be leaking around the adjustment screw too. Bummer. It's late, I'll deal w/ it tomorrow. Might have to tie a diaper to it to get to the jobsite tomorrow.



Scott,

I'm not familiar will what a Mallory looks like other than pictures, so I can't answer your question. According to HVAC this pump is internaly bypassed. I think that means it drips on the ground or something. LOL Really, if I can get the leak(s) fixed and it lasts, It's a great deal. Just might have to hang a catch bucket under it. Good thing it's 4x4.

I always use teflon sealant on threads. Copper and aluminum are a bad mix; guaranteed corrosion!:--)

 

[tmacc]

OK, Here's an update.

jsimpson, I used Gasoila on the threads first and it didn't work. Twice really. Needed something that had some body to it and the Permatex is what I had on hand. I'm very familiar with galvanic reactions. I'm going to use some yellow teflon tape when the new pump comes.



Well, When I started the truck this morning it was really leaking bad. I thought I was going to have a mess when I got to the job site 45mi away. However, when I got there it was pretty dry. Just a little damp. I think it's leaking around the input port now, but I think the gaskets on the inspection covers were leaking this morning. Don't know why it stopped. Heat maybe. The Thyokol syndrome. Wasn't that cold this morning.



I called Summit and they are sending a new pump next day. Great company to deal w/. They even credited my card for the Carter that I was going to send back. (Sold it this weekend. I've called them to straighten that up)



Now for the good stuff. This thing Rocks!!Oo. I'm reading 16. 5psi at idle, 16psi at cruise and I can't get it below 13. 5psi at WOT and I tried. Really, I tried alot. I've got the pump set up w/ 3/8"pipe/-6 male flair adapters on the pump and -6 female flair/3/8" barb to the fuel lines. I have a cutoff valve between the pump and the tank, so I can change the pump out in less than 30 min. and half of that time is getting tools together. W/ some marine electrical connectors, one can keep a spare around in case this thing takes a dump and have it in w/ two wrenches and a 7/16" socket for the mounting bracket.



So, there you go. I'll keep you posted when the new pump comes.

Sounds like a great set up Tom. Rubberneck also had a problem with the Summit pump leaking, glad to hear that Summit is taking care of you.



Real smart move putting a shutoff valve before the pump. I didn't, but plan on the same this summer.



I use paste called TFE Paste made by Master Plumber for all of my fuel line fittings. Works well with the smaller fittings, I tried it on my aux. tank last fall and it failed at the drain plug (diesel seeped right through). Huge mess, ended up pumping 110 gal. into a buddies fuel oil tank ( he was happy) to fix the problem. I have never had a leak with the paste on the smaller -AN and NPT fittings.

[tmacc]

Well!? Where's FedEx???

Got some of the yellow teflon tape and marine corrosion resistant connectors. Got some of the TFE paste too, but after re-reading Scott's post, I think I'll stick w/ the yellow tape and the Gasoila teflon paste. BTW, none of the Permatex products are gasoline resistant. Wonder if that includes diesel?



Now if the darn pump would just show up. I just found out that Fed Ex has til mid-night to deliver normal next day air. Bummer!



Scott,

The only draw back to having a cutoff in the line is the pump is that much further from the tank. Probably another 8" or so. Considing what an improvement the new fp numbers are, I'm not sure the extra distance makes much difference though.

 

[Bigsaint]

Tom, I don't think 8" will make a difference. As long as you are below the tank with the pump mount you should be good to go. Check Summits site, maybe they have a way you can track the order??? Hoping you get the pump soon



I just ordered an Earls -8AN bulkhead shut off valve that they listed as being only 2 3/4" long. That coupled with a 3/8"NPT to -8AN fitting should only equal out to a bit over 3". Are you using something different??? I'm planning on trying a pump that looks real interesting very soon (read next week if all goes as planned). Watch for the post, the pump has allot of promise.

Scott,

Still no pump. No one was home, so driver did not leave it. Unbelievable! I'm basically in the country. It's not like someone walks by our house. Must be a new driver or something. Hopefully tomorrow. Have no idea what happen on Tues.



The ball valve sounds about what I have. By the time you add fittings and some hose to avoid sharp bends... . It adds up. Like I said though, with these pressures, I'm not concerned.



Looking forward to hearing about this new pump your planning on using.

[hammersley]

Wow - I say wow there guys....

Hey finally something that seems to work, but I almost feel like I'm in a middle of a brain surgery lecture. Can you folks do another first rate step by step setup on what you're doing so we can duplicate this procedure. I especially like the ability to change the thing fast if she fails. You know I never would have believed that fixing a fuel delivery problem like this would be so hard! I am simply amazed. Honestly if there was something I thought we had solved in vehicles it was fuel delivery. Live and learn.

 

[rubberneck]

WELL MAYBE, BUT NOT REALLY

well, i hope you have better luck with that summit pos than i did. I tried one on my truck and we installed one on another truck within a weeks time of each other. Mine started leaking first from the bottom cover plate and then started puking fuel out between the motor and the pump body. Good thing it wasnt a gasser electric pump motors and gas dont mix well i bet The other guys started doing the same with in two days of mine. Not to mention the stupid thing was so loud. Sounded like a weed wacker mounted under my cab. i know some others have had luck with the summit pump, but we did not. hope you have better luck. For what it is worth, both my truck and the other guys were switched to the mallory 140 pump, and his is already taking a dump. so we are still on the search. when my mallory (notice i said when not if) goes (. ) (. ) up, im going straight to the aeromotive a1000 (the red log as brandon calls it) and a return regulator with gravity feed. Im sick of this wimpy pump crappp

 

[Bigsaint]

Well, I didn't plan on posting until it was in... but BigBob asked for input... . https://www.turbodieselregister.com/forums/showthread.php?s=&threadid=38994



I don't know if it's a end all solution to our woes, but it beats the crap outta replacing a pump and or brushes every 3-6 months if it works out. I, too, am sick of this weak link.

Finally got the pump today. What a C**** F*****!

Got it installed. No leaks on my 10 mile test drive. The other one was leaking after less that 5 miles. FP is 17ish idle. Hard to tell since my Wetach is a 16 psi gauge. Cruise is 16ish and WOT is 15psi. I can't seem to adjust this one. May be a good thing. Took me a little long to install than 30 min since I had to install new adapters.



rubberneck, My first pump leaked from the same cover plates. I did notice that the rubber gasket, on the new pump seems to be more evenly "squished" around the cover. I thought I felt the phillips screws may have been stripped on the old one. I hope I have better luck than you and your friend. I thought that w/ Nowell having one on for a year, this might be a good thing. We'll see. If I have to, I can hook up the stock pump w/ a minimum of hassle. They are noisy, but only at idle.



Scott, I saw that post a little while back too. Can't wait to hear all about it. BTW used the TFE paste and yellow tape. Don't know if that was overkill or not, but it doesn't leak.



Hammersley, I have to give up the 'puter now. Teenage daughter has her arms crossed and is tapping her foot. I'll post more details tomorrow if no one else does.



I'll keep everyone posted on the longevity. I'll keep my fingers cross.
