Suggestions for in-tank fuel pump?

I need 45 PSI any suggestions for an in-tank fuel pump? My Volvo external proved it could not handel 95-100* BHCC temps. I dont like taking the strap out.

I used their external I believe they have internal pumps too. Why not use a stock GM pump?

I bounced that off Butch at BHCC, he indicated the mounting syst for the GM F body pump would not be easy to adapt over. But then again how many of use choose to do things the easy way !

I would use a stock GM AC Delco for the engine you have in the truck, when you do it document how, all of us running EFI in the heat need this...............bad! BTW here, Autozone, can get AC pumps, in fact the local store stocks them because the shops prefer them. cheaper than the dealer and a lifetime warranty.

One of these guys should be able to do it.

Toy4Todd just recently put a GM pump into his Cruiser tank (78 40). I'm not sure how easy it went in, but you might PM him or his email is toy4todd@yahoo.com

So do you think I can exchange my current Autozone , Volvo pump for a GM F Body pump! Yes the life time warranty is good. When ever I buy parts form those guys they ask about my 740 Turbo Volvo….. "ah ya its good". I just leave out the part about it being bolted to the underside of an FJ-40.

Ok I will be the ginipig on this one. Just like some of the guys I wheel with.. “send Mark in first, if the water sucks up his truck we can go around”

Not too hard to put a GM pump in a cruiser tank. I had mine set up this way until I gave up on the tank location. Then I moved the same set up to the Beetle tank under the bed. Cut the top out of a stock GM tank so you keep the flange, cut a 4" hole in the top of the tank you want to use, weld the flange over the hole. Now you have a GM pump and sending unit in the other tank. Be sure to use the deepest part of the new tank as you want to pull out of the lowest area and the GM set up is often pretty long.
An alternative would be to use a surge tank with a welded on GM flange if your stock tank is not deep enough. That option might even keep the pump cool when the fuel is low in the main tank.

Hey Mark, I think I went through 2-3 of those Volvo pumps myself when I owned this POS:
http://www.collegeinternetsolutions....images/me1.jpg

I remember the Volvos (like most electric HP fuel pumps) use a pre pump that is low pressure, before the high pressure. The HP one will run alone for sometime, but if there isn't decent pressure it before then it will crap out at some point early. Hence why I went through 2-3 of them. I pulled about 4 from the JY one day for $20, it was cheaper and easier replacing them every 20K or so than dropping the tank and replacing the pre pump. They always have the same symptom of crapping out too. The car/truck turns off randomly usually under throttle. The conditions cause 'intermittent' failure.

Those Volvo pumps will hold up for years and years, they need the right conditions tho. The heat probably just brought it out more easily. It also could be something related to Autozone though. You should have seen the 22RE timing chain kit they sold me

I do run a pre-pump that feeds a surg or header tank the HP pump feeds from. The main problem is the HP pump just gets too hot and shuts down. The second day it did this at BHCC I pack a shop towel with ice and shoved it between the HP filter and pump. Worked well, so well that just today I discovered dried up towel in the same spot! This is pump two, the first a JY sucker bit it in about three months. I replaced it with the life time sucker from AZ.

Ballard, I thought about that as well. I just have to deal with all the tank liner (Kreem) I put inside my tank I built. Arrrrg! Also a tank fresh from having fuel in it. !

now, here's a thought...build a separate high-pressure resevoir (like a quart or two) and incorporate the internal high-pressure pump in there...supply it with a low-pressure pump outside the tank. That not only solves the cooling of the HP pump but also gives you reservoir for extreme camber situations

hhhhmmmmm

YUP got it. It works for extreme camber situations. Now it is not two qts. more like a pint. (mmmmm a pint sounds good right now ) This is fed by the low pressure pump and also has the motor return line feeding into it. The HP pump draws from the lowest point on the tank and the highest point has the one and only RTN to the fuel tank. Works great and I would not run it another way. But remaking this would allow for an easier install of the HP pump. The only issue would be building it large enough to allow for good cooling.

Your discussing this jinxed my truck(FJ40 with TPI) yesterday on a trip out 8E to Sunrise highway for some camping... the JY high pressure fuel pump just got too hot and it quit pumping on sunrise highway. I run the same sort of setup wiht a LP pump pumping to a 1.5 quart reservior and the HP pump(the same pump in Volvos, Audis, Nissans, BMW's etc) draw from there...

Had to ice it down and it started working again for about another 30 minutes...was fine on the return trip, but it is all down hill...so less engine compartment heat.

Right. That's what I was talking about with the surge tank. If you use the GM pump, you could use the GM flange as well for easy servicing, If you use an aftermarket pump you would need a way to access that pump like a screw on cap or an access plate.

DOH! *&**#$$%* fuel pumps! The other option is to build a cooler jacket for the pump then pump ice H20 through the jacket or set up AC just for the HP pump or.....

Ballard, good thinking on putting it on the surg tank.

I am heading over to my friends shop(BMW stuff) and look at what is around for in tank pumps, as my surge tank is easily big enough to house a submerged pump... will post up later...

[wngrog]

Mark,

To me, going through one pump in 2 years tells me I just don't need to wheel when its 100 degrees

I am sticking with the external pump and adding a cooler between the tank and the pump!
