URD Fuel Pump Kit Hard Start

I installed the URD Walbro 255 fuel pump kit this weekend. The truck takes 3 to 4 seconds of cranking before it starts now. Before the install it work start within 2 seconds of cranking. If I let the truck run for a little bit shut it off and immediately restart it the truck will start like it did before the fuel pump swap. I have had it running and have checks for leaks and everything seems fine but the truck cranks significantly longer before starting after the install. I am thinking a leak somewhere that is decompressing the fuel line, but I am not seeing any fuel dripping. Any ideas or similar issues from someone that has done this install? Thanks.
I will call URD Tuesday if I have time. Work is going to be a bitch this week.

 

Sounds to me that you have a problem with the intank line. Either it is pinched/bent, not tightened properly, or split.

Has happened quite a few times during other people's installations.

 

Glad to know....

 

Yea thats what Gadget said today when I called. The truck died just after leaving work today. I had a friend tow it back to where I work and will drop the tank and see whats up in the parking lot sometime soon. I have alot going on so it may be a day or two before it gets fixed. Gadget said the clamps sometimes cut into the hose inside the tank if they are to tight. It sucks because it now has 1/2 tank of gas. I am glad I did not fill it all the way up like I usually do.

 

I would order a spare Gates submersible hose, 12", just to be on the safe side.

 

How long was the pump installed before the line split? Did you over tighten the clamps on the fuel pump?

How do you pressure test the lines?

Did you have a blockage in the fuel filter? That would be an easy fix.

 

Fixed. Intake line hose clamp was loose. My fault. If anyone in the Phoenix plans to do this mod PM me and I will help. I have dropping the tank down to science now.

 

I'm about 3 weeks away from installing, im in Tempe!

 

I am in Gilbert. I will PM you my Phone # and address. Come over to my place and we will get her done. I have a tranny jack that will help with removal and install. I also have a tool for removal of the big plastic ring on top of the tank. Should only take 2 hours or less to get it done.

 

Awesome I would really appreciate that especially since you have hands on experience doing it!

 

Glad to help. Try to have your fuel level low when we do the install.

 

Lol 21 gallons of fuel to lower, doesn't sound fun. I'll make sure it's close to E

 

And the reason why forums can be so awesome. If the 320 is around the same price ans the 255, why not get the larger?

If they are two far different, the 255 will still be more than adequate.

 

Anyone know or have a photo of the fuel tank outlet fitting. Curious if it is quick disconnect or molded on.

Thanks

I don't have a picture, but the cap which the lines on the outside of the tank attach to, are molded.

 

Thanks.

So for my add on fuel filter, I'll plan to use the oem fuel lines, mount the filter, then build the line from the filter to the oem chassis tube as quick disconnect.

As you mentioned to me before, I should still drop the tank and remove the oem filter.

Consider too, this is not to increase performance, rather obtain better maintenance serviceability.

I want to say the stock filter and pump are one unit. So you will need to change the pump if you want a filter outside the tank. Someone correct me if I am wrong.
