electric fuel pump relay problems!!

[Moremph]

I was curious as to what kind of relays everyone is using with thier superduty fuel systems. I can not seem to keep a relay in my truck. They last a couple months and then they stick on. They get corroded inside and freeze up. what are you guys using, I have been using the standard 30 amp relays, like used in most automotive applications


Thanks Travis

i went though 4 before i got a good one,like every 2 to 3 months it was going out,its been 6 months since last mine went out.but thats the same relay i run.i keep one in the tool box just in case

im running the same relay that the superdooties run i used that blank relay spot in my under hood fusebox

Same one for over a year, almost a year and a half.
Need one? I bought a large qty and got a good price, about 1/8 of retail. If you want one I will gladly send it to you.

plain ol' generic relay, haven't had a problem in over a year. of course now I'm going to be stuck tomorrow morning [img]/ubbthreads/images/graemlins/tongue.gif[/img] (although technically I have a spare because of having dual pumps [img]/ubbthreads/images/graemlins/grin.gif[/img] )

any chance your wiring on either side of the relay is a little rough? not getting a good ground or something?

I just picked up a S.D. pump. Now I need to figure out how to do the wireing. Could somebody explain how to wire the pump useing this method?????

Also I am glad to read early that I should carry spare relays. Anything else?????

open teh underhood fuse box teh last place in it has no relay , jsut remove teh fuse box and wire thsi spot up.

I have a bunch of supposedly good ones at work, we get em from kenworth suppose to be better then the generics. haha. but thanks anyway rick.

swh22 how do you have your duals set up. one to each head, or compounding?

Hay Travis, I'm using the standard relays on my twin pump setup 1 relay for each pump. I do notice every now and again one of the relays will stick on and keep the pump/pumps running after I've shut down the truck. I just pop the hood and give it a tap and it stops. It's only done it 2-3 times and hasn’t done it in over a month now.

I have them in parallel, right now I am only running one pump (the other is unplugged at the relay and capped at the pump outlet) and don't have a problem holding 50psi. I wanted to do it all at once rather than try to add a second pump in a year or two when I really need it. Plus I found two cheap ones on ebay when I was gathering parts.

I have a one-way valve that I am going to install in the second pump, then I can un-cap it and plumb it into the "T" that I have after the two pumps. Then I'll put a switch on my dash to turn on the second pump when I need a little extra juice. Might just get to it this weekend. But probably won't NEED the second pump until I go to Stage II's or bigger.

Let's see if this comes through...

that is exactly what i have been noticing to with the relays, walk by the truck and here the fuel still running!!

No, I have a 5/8" pick up going into a filter housing then splitting into 2ea 1/2" line then into 2 ele pumps then into another filter then 2 lines going up to the motor, 1 for each head.
I have some pic's in my sig.
