Geno's Transfer Pump

[BarlowCummins]

Hi everyone, my transfer pump is on its way out and I am going to buy Geno's replacement transfer pump. My question to you guys is how hard is it to replace and does anyone have a set of instructions? I have searched the forums and can't seem to come up with anything.

Thanks, Corey

They are easy to change. 4 socket head cap screws (5 mm allen wrench IIRC), unplug the wiring harness and disconnect the fuel line. I cut the old fuel line off of the old pump and slit the hose to get the factory fuel line connector off and re-used it. It is probably an hour job tops.



PM me your email and I can send you some pictures of the dual lift pump bracket I just put on. It shows the dual pumps but you can get the idea. I had the easiest time going at it from underneath the truck.

Takes about 1/2 hour (a little longer if the O ring doesn't seat the first time--- Grrr). Instructions are included. I'm on #2 lift pump. I think FASS is my next mod.

I ordered mine from Geno's and installed about 6 months ago in under 30 minutes; not a hard job at all. It came with an inline filter which i will probably be removing this weekend.

FYI the filter supplied is more of a strainer to protect the pump. Freightliner used them on the older B and C series engines for years. You may never have to replace it.

It will only strain out small stones

i think the easiest access is to remove the front tire and fender well. i couldn't reach laying under the truck, and ended up laying over the motor and working by feel. then i found out later it probably would have been easier to go in through the wheel well

I plan on removing it this weekend to see what trash might have collected inside.

I did it the first time by removing the wheel well liner but I left the tire on. Removing the tire would probably help a lot. Then I got to try from underneath the truck thanks to a misalignment and a leaky o-ring the first time around! I think it really is a matter of personal opinion on this one. Both ways seem to work well and provide good access.

I unfortunately had to change mine on a rock driveway in the dark with a lousy flashlight. I just couldn't see anything from the bottom or get in a position without a sharp rock sticking me somewhere.

 

[BarlowCummins]

Thanks for all the replies guys. I will be ordering the pump this week and your pointers have giving me some confidence for changing th pump.

 

[BarlowCummins]

Well I got the new pump on and my fuel pressure has jumped from 7psi to 9-10psi. Has anyone had this happen to them? I have always had 7psi since I put the guage on a few years ago.



Thanks Corey

Fuel / Transfer Pump

My question is,, does any know how may factory pumps have failed, has a poll ever been taken to find out.

I would hate to be out in the High Desert of Southern Oregon and have it go gunny bags.



I cannot decide if I want to go with the factory type Geno has or the FASS

or just get the factory type and carry it along If mine should go out.

How many miles did it take to need two lift pumps ??

How many miles did it take to need two lift pumps ??

I had ~55k miles when the lift pump went. Now be advised, this only happened a few months ago as we don't drive the truck all that much. Bought the truck Memorial Day of '04. The original pump made it just under 5 years. Truck only has 60k on it now.

Since I knew the problem was coming, I carried a spare with me in the truck for about a year prior to it taking a dump. I spend a lot of time camping in Nevada and would kick myself if it crapped out 100 miles from anywhere. Luckily, it took a dump in the driveway as my wife was leaving for work. My wife wouldn't use the term "lucky. " :-laf I got home from work and had it going again right quick. Now I'll probably just get an Air Dog since they're CARB certified here in CA and smog checks are coming in 2010.

If I'm you and toolin' around anywhere in the truck, notwithstanding the boonies of eastern Oregon, I'd definitely be carrying a spare. Also, have you owned your truck since new? Does it still have the factory pump? If it's used it may have been converted to intank prior to you getting it. Just a question... good luck.

I bought my 03 with 79k mi and replaced my original style lift pump at 154k as preventative measure. No indication it had ever been replaced. I went with the GDP Walbro pump, which worked well (one pump failure in 377k more miles). But, if the original pump had been available I would have probably just bought one, replaced my existing pump, and carried the old pump as a spare.

This has been a good thread for me as I have been thinking about the pump.



Most of our trips with the 5th wheel are in out of the way places where there is dang sure no cell phone service and no tow trucks handy.



I went out and looked under the hood at the pump and from underneath and have made my mind up. Will go with the FASS pump from GENO's garage.



My fishing buddy has a big shop and I'm sure he will help me install it.



Thanks for all of your input, this is such a great forum.



I Remember when we had the 95 Dodge and the Killer Dowel Pin came up on the TDR and the kit that got mailed around made it an easy repair. .
